Description : Banana and plantain (Musa spp) are important foreign exchange earners in Guyana and the Windward Islands of the Caribbean. Black Sigatoka Disease (BSD) also referred to as black leaf streak disease is one of the most destructive diseases of banana and plantain and is present within the region. In Guyana within two years following its introduction in 2008, the industry was totally decimated, recording a 100% decline, turning the country to a net banana importer. Also, from 2009 ? 2012 the disease spread in the Windward Islands causing as much as 100% decrease in the export of banana. The disease is caused by the ascomycete fungus, Mycosphaerella fijiensis (anamorph Pseudocercospora fijiensis) and is aggressive, challenging to control and results in enormous crop damage if left uncontrolled. In an effort to develop an integrated management approach to the disease the Caribbean Agricultural Research and Development Institute (CARDI) with financial assistance from the Caribbean Development Bank (CDB) is evaluating five FHIA banana and plantain accessions and eight IITA plantain accessions for tolerance to BSD. The evaluation is presently conducted in four Caribbean countries, Dominica, Guyana, St Lucia and St Vincent and the Grenadines. In each country, four distinct agro- ecological zones were selected for the trial evaluation blocks and using a randomized block design, four blocks were established in each country. Five FHIA accessions: FHIA-01, FHIA-03, FHIA-18, FHIA-21 and FHIA-23 are being evaluated in Dominica, St Lucia and St Vincent and the Grenadines whereas, plantain accessions: PITA-17, PITA-21, PITA-22, PITA-23, PITA-24 and PITA-26 are to be evaluated in Guyana for tolerance to the disease. Cavendish are used as regional controls and as borders rows to increase disease pressure. The disease parameters evaluated are youngest leaf spotted (YLS), disease development time (DDT), leaf emission rate (LER), disease severity at 6 months, bunch emergence and harvest, and index of standing leaves. Agronomic data; days from planting to flowering, bunch weight, number of hands in bunch, average weight of hands and average number of fingers per hand and bunch, as well as organoleptic characteristics of both cooked and ripe fruits are also evaluated. The early data collection, of the FHIA only accessions, show trends in the disease tolerance and agronomic performance as well as their adaptability in the different agro-ecological zone. The trends indicate better disease tolerance of FHIA varieties with higher leaf counts before, at bunching and at harvest. The organoleptic test shows a preference to FHIA 03 and FHIA 21. La banane et le plantain (espèces de Musa) sont les acquéreurs de devises étrangères importants en Guyane et en Îles du Vent des Caraïbe. La maladie noire de Sigatoka (schéma) également désignée sous le nom de la maladie noire de filet de feuille est l'une des maladies les plus destructives de la banane et du plantain et est présente dans la région. En Guyane dans un délai de deux ans après son introduction en 2008, l'industrie a été totalement décimée, enregistrant une baisse de 100%, tournant le pays à un importateur net de banane. En outre, à partir de 2009-2012 la propagation de maladie en Îles du Vent causant pas moins de la diminution de 100% de l'exportation de la banane. La maladie est provoquée par le champignon d'ascomycète, fijiensis de Mycosphaerella (fijiensis anamorph de Pseudocercospora) et est agressive, contestant pour commander et les résultats dans l'énorme culture endommagent si laissé incontrôlé. Dans un effort de développer une approche intégrée de gestion à la maladie l'institut agricole des Caraïbes de recherche et développement (CARDI) avec l'aide financière de la banque de développement des Caraïbes (BDC) évalue des adhésions de banane et de plantain de cinq FHIA et huit adhésions de plantain d'IITA pour la tolérance au schéma. L'évaluation est actuellement effectuée quatre pays des Caraïbes, Dominique, Guyane, St Lucia et Saint-Vincent-et-les Grenadines. Dans chaque pays, quatre agro zones écologiques distinctes ont été sélectionnées pour les blocs d'essai d'évaluation et employant une conception de bloc randomisé, quatre blocs ont été établis dans chaque pays. Cinq adhésions de FHIA : FHIA-01, FHIA-03, FHIA-18, FHIA-21 et FHIA-23 sont évalués en Dominique, au St Lucia et au Saint-Vincent-et-les Grenadines tandis que, des adhésions de plantain : PITA-17, PITA-21, PITA-22, PITA-23, PITA-24 et PITA-26 doivent être évalués en Guyane pour la tolérance à la maladie. Cavendish sont employés en tant que contrôles régionaux et comme rangées de frontières pour augmenter la pression de la maladie. Les paramètres de la maladie évalués sont la plus jeune feuille repérée (YLS), le temps d'élaboration de la maladie (DDT), le taux d'émission de feuille (LER), la sévérité de la maladie à 6 mois, émergences et récoltes de groupe, et index des feuilles debout. Données agronomiques ; des jours de la plantation à la floraison, du poids de groupe, nombre de mains dans le poids de groupe et moyen des mains et du nombre moyen de doigts par main et groupe, aussi bien que les caractéristiques organoleptiques des fruits cuits et mûrs sont également évalués. La collecte de données tôt, des adhésions de FHIA seulement, exposition tend dans la tolérance de maladie et la représentation agronomique aussi bien que leur adaptabilité dans la zone agro-écologique différente. Les tendances indiquent qu'une meilleure tolérance de maladie des variétés de FHIA avec une plus haute feuille compte avant, à se rassembler et à la récolte. L'essai organoleptique montre une préférence à FHIA 03 et à FHIA 21.

Description : Plant genetic resources are instrumental in the adaptation of agriculture to social and environmental change. They are the backbone of research and breeding programs aimed at the development and transfer of new crop varieties best suited to consumers? needs and tastes and to new farming systems. To this aim, plant germplasm collections have been constituted worldwide. Securing such collections requires substantial human and financial investments that can prove difficult to maintain on the long run for small countries and territories such as most Caribbean countries. In Guadeloupe and Martinique, INRA and CIRAD have constituted large plant germplasm collections of tropical crops over several decades. They joined forces in 2010 to create the Tropical Plant Biological Resource Center of the French West Indies (CRB-PT), which is affiliated to both institutions. In this paper, we describe CRB-PT?s collections, services provided to end users and research programs as well as scientific and technical networking strategy. Les ressources génétiques d'usine sont instrumentales dans l'adaptation de l'agriculture au changement social et environnemental. Elles sont l'épine dorsale de la recherche et les programmes d'élevage ont visé le développement et le transfert de nouvelles variétés de culture adaptées aux besoins et aux goûts des consommateurs et à de nouveaux systèmes d'exploitation agricole. À ce but, des collections de matériel génétique d'usine ont été constituées dans le monde entier. La fixation de telles collections exige les investissements humains et substantiels qui peuvent être difficile à maintenir sur le long terme pour de petits pays et territoires tels que la plupart des pays des Caraïbes. En Guadeloupe et Martinique, l'AICN et les CIRAD ont constitué de grandes collections de matériel génétique d'usine de cultures tropicales au-delà de plusieurs décennies. Ils ont joint des forces en 2010 pour créer le centre de ressources biologique de plante tropicale des Antilles françaises (CRB-PT), qui sont affiliées aux deux établissements. En ce document, nous décrivons les collections de CRB-PT, services fournis aux utilisateurs et les programmes de recherche aussi bien que la stratégie scientifique et technique de mise en réseau.

Description : Breeding new interspecific banana hybrid varieties with pests and disease resistance characters is instrumental for the development of pesticide-free agroecological banana farming systems. Such breeding relies on the combined use of Musa acuminata and M. balbisiana parents. Unfortunately, infectious alleles of endogenous Banana streak virus (eBSV) sequences are present in the genome of M. balbisiana genitors. Upon activation by biotic and abiotic stresses, these infectious eBSVs lead to spontaneous infections by several species of Banana streak virus (BSV) in interspecific hybrids harbouring both M. acuminata and M. balbisiana genomes. In this work, we show that M. balbisiana diploid genitors available for breeding host at least one infectious eBSV. We also show how we segregated infectious and non-infectious eBSV alleles in seedy M. balbisiana diploids through self- pollination or chromosome doubling of haploid lines. We report on the successful breeding of M. balbisiana diploid genitors devoid of all infectious eBSV alleles following self-pollination and on the potential of breeding additional M. balbisiana diploid genitors free of infectious eBSVs by crossing parents displaying complementary eBSV patterns. This work paves the way to the safe use of M. balbisiana genitors for breeding banana interspecific hybrid varieties with no risk of activation of infectious eBSVs.

Description : The Sargassum seaweed [Sargassum natans and S. fluitans] can be classed as a perennial invasive weed problem in all the Caribbean islands. It has been shown to affect fisher-folks, sea bathers, and tourists. It is proving to be costly to remove; in addition to its offensive odour which hampers the clean-up operations. The University of Trinidad and Tobago at the BAFT campus is engaged in series of activities to find suitable uses of the seaweed as animal feed, and as soil medium and ameliorant. This study aimed at evaluating the suitability of the seaweed as a growing media for the production of sweet peppers [Capsicum annuum var. annuum] using different percentage of the weed (0, 25, 50 and 100%) with soil under greenhouse conditions. The crop growth and development and yield were monitored. The results indicated that the plant height [Y pl ht = 16.6 + 0.3 DAT - 0.11 TRT] and leaf number [Y no.lvs = 0.90 + 1.04 DAT - 0.206 TRT] increased as age of the crop increased, but decreased with the increase in percentage of seaweed/ soil mixture. A similar response was observed for the flower buds and fruits numbers and percentage soil mixture. The medium had no effect on the crop transpiration and net photosynthesis rate [PN] , photosynthesis active radiation[PAR] , and stomatal conductance. A nutrient analysis of the medium was also conducted.

Description : Under tropical and sub-tropical climates, a sustainable development of agriculture is challenging because of the pest pressure with favorable weather conditions. Implementation of appropriate cropping systems including growing cover crops and crop rotation plays a critical role, which can break up the food chain and life cycles of field pests. Some field trials have demonstrated that among all tested summer cover crops, sunn hemp (Crotalaria juncea L. cv. Tropic sun) can grow vigorously during the rainy summer, cover the land quickly and densely, and it can produce a large quantity of biomass in two to three months. More importantly, sunn hemp can suppress soil root-knot nematodes via releasing some nematicides through its roots and through the decomposition of plant residues. Therefore, growing cover crop â? ? sunn hemp during the crop off season and rotating with valuable vegetable crops in the growing season has become a promising cropping system under the subtropical climate. Such a result may have a potential to be implemented in Caribbean countries to improve the sustainable development of agriculture.
