Abstract
Background: Identification of transgressive recombinant inbred lines (RILs) that can be use as pure-line cultivars is the prime objective of a breeder in self-pollinated crops including groundnut.
Aim: Thus, identification of such promising segregating generations assumes importance. This can be achieved by predicting the transgressive RILs that could be derived from advanced generations of segregating population.
Materials and Methods: In our study we predicted and validated transgressive RILs derived from cross TMV 2 × GPBD 4 for five quantitative traits based on estimates of mid parental value [m], additive genetic effects [a] and additive genetic variance [σ2A].
Results: the frequency of transgressive RILs was higher for all the five traits. Primary branches per plant had highest frequency of predicted transgressive RILs with minimum population size of 6.95. Narrow difference between the predicted and realised frequency of RILs was seen.
Conclusion: Our results indicate that this approach could be the efficient in selecting the best breeding population out of many number of crosses made.
Keywords: Additive genetic effects, additive genetic variance, minimum population size, transgressive segregation
