Genetic analysis of yield, protein, oil and other related traits in soybean
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 indicated that for traits like protein content, grain yield and days 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
Studies on Harvest Index in Soybean
According to Vogel et 01. (1963) the r.i.ght approach to increase the seed
yield is the improvement in total biological yield and/or harvest index. Further,
harvest index is a highly conservative and stable character (Spaeth et 01; 1984,
Mercellos, 1987) and accounts for 95% variation in seed yield alongwith growth
rate (Takeda et 01., 1979). These factors empha"ize the importance of harvest
index in identifying the most efficient genotypes with superior biological and seed
yielding abilities (Sharma et af., 1987). But the study of genetic architecture of
harvest index is essential before embarking upon selection based 011 it. In the
present study heterosis, combining abil ity and gene effects for harvest index were
investigated..........
