GENETIC ANALYSIS OF YIELD, PROTEIN, OIL AND OTHER RELATED l'RAITS IN SOYBEAN

Published on

Combining ability analysis was carried out for yield, protein and oil content and other
traits related to productivity in a half diallel set involving seven parents. The estimates
of sca variances were higher than gca variances for all the seven characters. Values
of the ratio ;ai 2 indicated that for traits like protein content, grain yield and days
2ag + as
to maturity, non-additive gene effects were predominant. The mean values of parents
reflected their combining ability effects in general and genotypes KHSb-2 and DS 74-62
were good general combiners for yield and yield contributing characters. The high
performing crosses for yield involved parents with High x Low and Low x Low gca
effects. Based on the results, suitable breeding strategies are suggested.
