Prediction of seed-yield potential of common bean populations
Earliest possible prediction of seed-yield potential of autogamous crop populations increases breeding program efficiency by saving time and resources. Alternatives for obtaining seed-yield predictions were compared by evaluating four common-bean populations in F1 and F2 generations together with the parents. Mean components (m + a’ and d) and variances were estimated. The potential of each pop...
متن کاملPotential of wild common bean for seed yield improvement of cultivars in the tropics
Singh, S. P., Molina, A. and Gepts, P. 1995. Potcntial of wild coInmon bean for seed yield improvement of culdvars in the tropics. Can. J. Plant Sci. 75: 807-813. Thirty nine wild or weedy common bem (Plaseolus vulgarisL.) accessions, representing the two extremes of geographical range of distribution and domestication of cultigens in the Americas, were crossed to a highyielding, small-seeded c...
متن کاملVariability of Colletotrichum spp in common bean.
The Colletotrichum genus presents large genetic variability, as demonstrated by the occurrence of several pathogenic races and phenotypic traits. The objective of this study was to characterize 22 strains of C. lindemuthianum and Colletotrichum spp recovered from anthracnose lesions and bean scab, and to verify the relationship between species of the Colletotrichum genus, which inhabit anthracn...
متن کاملItalian Common Bean Landraces: History, Genetic Diversity and Seed Quality
The long tradition of common bean cultivation in Italy has allowed the evolution of many landraces adapted to restricted areas. Nowadays, in response to market demands, old landraces are gradually being replaced by improved cultivars. However, landraces still survive in marginal areas of several Italian regions. Most of them appear severely endangered with risk of extinction due to the advanced...
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 ...
