PREDICTION AND VALIDATION OF THE FREQUENCY OF RECOMBINANT INBRED LINES SURPASSING PRE-DETERMINED STANDARDS FOR QUANTITATIVE TRAITS IN DOLICHOS BEAN(LABLAB PURPUREUS L. SWEET) VAR. LIGNOSUS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 18
Abstract
Development and use of an objective criterion for selecting a few potential crosses to maximize the frequency of superior pure-lines would help increase the pace and efficiency of any self-pollinating species with Dolichos bean being no exception to this. Probability of RILs that transgress the parental and/or any pre-determined rangecan be predicted based on additive [d], additive × additive epistatic gene effects [i] and additive genetic variance (σ2A) estimated in initial selfing and/or backcross generations derived from a cross. An investigation was conducted to predict and validate the frequency of F5 RILs derived from HA 10-8 × RIL 180 that surpass the limits of their parental phenotypes and of check variety, HA 4 for nine quantitative traits.A fairly good agreement was observed between observed and predicted frequency of RILs that transgressed higher scoring parent only for primary branches plant-1. On the other hand, good agreement was noticed between observed and predicted frequency of RILs that transgressed the lower scoring parent for dry pod yield plant-1 and 100-dry seed weight. The agreement between predicted and observed frequency of RILs that transgressed either of the parent was rather poor for plant height, primary branches plant-1, racemes plant-1, raceme length, dry pods plant-1 and dry seed plant-1. The poor agreement between predicted and observed frequency of RILs for these traits was attributed to linkage disequilibrium between the genes controlling these traits.
