对8种玉米雄性不育细胞质来源的 Mo17不育系和 Mo17自交系与埃及205等7个自交系按不完全双列杂交配成63个杂交组合的籽粒产量进行了研究,同时也探讨了有关的11个农艺性状。结果表明,玉米异细胞质 Mo17雄性不育系和 Mo17自交系所配杂交种的籽粒产量无明显差异,各杂交种的穗长等11个农艺性状的表现亦基本一致。因此,在玉米杂种优势利用中就可以利用同一杂交种的细胞质类型。
The grain yield of eight hybrid maize CMS lines derived from male sterile cytoplasm and Mo17 inbred lines and Egypt 205 and other seven inbred lines based on incomplete diallel crosses were studied. At the same time, The related 11 agronomic traits. The results showed that there was no significant difference in grain yield between hybrids of Ma17 and Mo17 inbred lines, and the performance of 11 agronomic traits such as spike length of all hybrids was also consistent. Therefore, it is possible to utilize the cytoplasmic type of the same hybrid in the utilization of maize heterosis.
