Interspecific crosses between Glycine max (L.) Merr. and G. jormosana (L.) Merr. showed a wide variability for days to flowering, maturity and duration from flowering to maturity. The results indicate that the character days to flowering was governed by polygenes. Earliness in F2 may be due to the characters less number of days to flowering, and shorter period from flowering to maturity contributed by G. max and G. jormosana, respectively. Heritability of both these characters is high, showing less environmental influences.



Soybean, interspecific crosses, earliness, heritability.
