Evidence for Introduction Bottleneck and Extensive Inter-Gene Pool (Mesoamerica x Andes) Hybridization in the European Common Bean (Phaseolus vulgaris L.) Germplasm
Common bean diversity within and between Mesoamerican and Andean gene pools was compared in 89 landraces from America and 256 landraces from Europe, to elucidate the effects of bottleneck of introduction and selection for adaptation during the expansion of common bean (Phaseolus vulgaris L.) in Europe. Thirteen highly polymorphic nuclear microsatellite markers (nuSSRs) were used to complement c...
متن کاملSegregation and Recombination in Inter-Gene Pool Crosses of Phaseolus vulgaris L
Variation for segregation ratios and recombination rates was analyzed in crosses involving 13 common bean (Phaseolus vulgaris L.) genotypes from different gene pools and races. The segregation of RFLP, isozyme, and phaseolin markers belonging mostly to linkage groups D5 and D7 was analyzed in 11 F2 populations derived from Middle American x Andean, and Andean x Andean crosses. An average level ...
متن کاملEpistasis in intra- and inter-gene pool crosses of the common bean.
Epistasis has been shown to have an important role in the genetic control of several quantitative traits in the common bean. This study aimed to investigate the occurrence of epistasis in intra- and inter-pool gene crosses of the common bean. Four elite lines adapted to Brazilian conditions were used as parents, two from the Andean gene pool (ESAL 686; BRS Radiante) and two from the Mesoamerica...
متن کاملAbortive Seed Development in Common Bean (phaseolus Vulgaris L.)
INTRODUCTION Embryo defective mutants in Phaseolus vulgaris obtained by Ethyl methanesulfonate (EMS) induction were studied to determine the structural and molecular basis of seed abortion in this species. In the wild-type, the classical pattern of seed development showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue, and seed coat. On the contrarily, EMS mutant ...
متن کاملGene/QTL discovery for Anthracnose in common bean (Phaseolus vulgaris L.) from North-western Himalayas
Common bean (Phaseolus vulgaris L.) is one of the most important grain legume crops in the world. The beans grown in north-western Himalayas possess huge diversity for seed color, shape and size but are mostly susceptible to Anthracnose disease caused by seed born fungus Colletotrichum lindemuthianum. Dozens of QTLs/genes have been already identified for this disease in common bean world-wide. ...
