AFLP markers linked to resistance against Striga gesnerioides race 1 in cowpea (Vigna unguiculata).
Amplified fragment length polymorphism (AFLP) analysis was used in combination with bulked segregant analysis (BSA) to identify molecular markers linked to two cowpea (Vigna unguiculata (L.) Walp.) genes conferring resistance to Striga gesnerioides race 1. After AFLP analysis of an F2 population derived from a cross between the resistant cultivar Gorom and the susceptible cultivar Tvx 3236, sev...
متن کاملAn improved genetic linkage map for cowpea (Vigna unguiculata L.) combining AFLP, RFLP, RAPD, biochemical markers, and biological resistance traits.
An improved genetic linkage map has been constructed for cowpea (Vigna unguiculata L. Walp.) based on the segregation of various molecular markers and biological resistance traits in a population of 94 recombinant inbred lines (RILs) derived from the cross between 'IT84S-2049' and '524B'. A set of 242 molecular markers, mostly amplified fragment length polymorphism (AFLP), linked to 17 biologic...
متن کاملIdentification of AFLP markers associated with flowering time and ornamental traits in Chrysanthemum
Flowering period and longevity play important roles in determining the quality of commercial flowers. Marker-trait associations for eight flowering and 12 ornamental traits have been studied using a GLM and MLM analysis with a set of 2099 AFLP polymorphic markers in Chrysanthemum. The GLM model identified 453 markers for phenotypic traits whereas the MLM association analysis model revealed a t...
متن کاملAnalysis of AFLP Variation of Taro Population and Markers Associated with Leaf Blight Resistance Gene
The development of molecular techniques, in particular the use of molecular markers have been used to identify markers linked to useful traits and made great advances in recent years. Amplified fragment length polymorphism (AFLP) analysis was used to analyze the geographical differentiation, phylogenetic relationships and to identify molecular markers linked to taro leaf blight resistance genes...
متن کاملPhenetic relationships among different races of Striga gesnerioides (Willd.) Vatke from West Africa.
Striga gesnerioides is a root hemiparasite that primarily parasitizes dicotyledonous species, including cowpea (Vigna unguiculata L.) and other legumes. Based on the differential resistance response of various cultivars, landraces, and breeding lines, it has been proposed that several distinct races of cowpea-parasitic S. gesnerioides exist in West Africa. In this study, we used amplified fragm...
