A comparison of two breeding procedures in two crosses of mungbean (Vigna radiata (L.) Wilczek)

Two breeding methods, single-seed descent (SSD) and bulk (B) were compared in the segregating generations of two crosses (HG 19 x Black Neelalu (BN) and ML 5 x BN) of mungbean, Vigna radiata (L.) Wilczek. Yield trials were grown in F₃, F₄ and F₅ generations. There was no evidence for a directed shift in mean performance for days to maturity, No. of branches and seeds/pod. There were sporadic differences in variance and CV estimates of bulk and SSD populations most likely due to sampling error. The estimates of heritabllity and genetic advance were moderate to high, indicating that improvement through selection would be feasible. There was no consistent difference in the expected genetic advance from the three SSD and the bulk populations.
