COMPARATIVE EFFICIENCY OF 4 SELECTION METHODS FOR DERIVING HIGH-YIELDING LINES IN MUNGBEAN [VIGNA-RADIATA (L) WILCZEK]

The comparative efficiency of four selection methods, viz., honeycomb (HC), pedigree selection (PS), single-seed descent (SSD) and the bulk method (BM), was assessed in three crosses of mungbean. The lines deri ved by each method, along with check varieties, were yield-tested in a compact family block design in F-5 and F-6 generations during summer and kharif of 1990. On the basis of the mean of the lines, the range, the number of superior lines over the best check, and the proportion o f the top 10% lines in all the crosses and generations, the honeycomb method exhibited superiority over PS, SSD and BM for yield per plant a nd its component traits. PS, SSD and BM did not differ from each other . The honeycomb and SSD methods were found suitable for deriving super ior lines for seed yield and pods per plant in mungbean.
