Studies on the application of multi-ovary character to hybrid wheat II.Heterosis and utilization of multi-ovary wheat

Using 24 F 1 hybrids derived from three multi ovary wheat(Mow) and 8 wheat,the heterosis and utilization of Mow was study.The results were as follows:The heterosis of plant height,kernels per head,grain weight per plant,1000 kernels weight decreased in this order.Hybrid of MOW had very high heterosis in the grain weight per plant,there is a 32.71% increase of yield as compared with the average of both parent in 18 crosses,among 12 crosses increased 3.41-42.84%.The heterosis mainly showed higher kernels per head ,the application of Multi ovary wheat should strengthen the improving of other agronomic characteristics
