杂交种的最佳适应水平决定着各种作物杂种优势实际利用的可能性。近年来育种家注意到,在许多异花授粉作物上选育群体杂种的研究具有广泛前途。显然,群体杂种是作物栽培中利用优势的最经济方法。近年开始了选育高粱群体杂种的研究。据报道,将试验和选择相结合
The optimal level of hybrids determines the possibility of actual utilization of the heterosis in a variety of crops. In recent years, breeders have noticed that there is a wide range of future research on breeding group hybrids on many cross-pollination crops. Obviously, group hybrids are the most economical way to exploit advantages in crop cultivation. In recent years, the breeding of sorghum hybrids began. It is reported that the combination of testing and selection
