Abstract:

Heterosis of F1 and F2 generations yield of 22 cross combinations with soybean M type male sterile linesW931A as female parent had been tested .The results showed :average over -parent heterosis of all F1 generations yieldreached 48 .96 %, ranging from 3 .78 % to 132 .16 %.Among these combinations , average over -standard heterosis ofF1 generation yield of 19 combinations reached 31 .06 %.ranging from 6 .04 % to 66 .06 %.Over -standard heterosis andover -parent heterosis of F2 generations yield reached 8 .30 % and -6 .24 %respectively .The results also showed :heterosisof F1 generations yield was closely related to the geographical origin of restoring lines(male parent).Over -parentheterosis and over -standard heterosis of the combinations yield from south ecological area were stronger 22 .93 % and24 .83 % than that from Huanghuai ecological area respectively .Heterosis of F2 generation yield depressed obviously andwas unsuitable to be utilized .
