通过对化学诱导雄性不育系和细胞质雄性不育系两个授粉系统所测配的杂交品种进行比较,利用化学诱导雄性不育系选育的杂交品种比细胞质雄性不育系选育的杂交品种含油量高,而且呈显著性差异,在产量上细胞质雄性不育系选育的品种在产量上较高,但在亩产油量上化学诱导雄性不育系选育的品种较高;同时在制种方面,化学诱导雄性不育授粉系统比细胞质雄性不育授粉系统的制种产量高,而且方便,经济。在测配组合利用方面,化学诱导雄性不育系授粉系统亲本来源广泛,组合测配自由,遗传变异范围广,容易选育出优势强的杂交组合。
By comparing the hybrids tested by two pollination systems of chemically induced male sterile lines and cytoplasmic male sterile lines, the hybrids bred by chemically induced male sterile lines were higher than the hybrids bred by cytoplasmic male sterile lines High oil content, and significant differences, the yield of cytoplasmic male sterile line breeding varieties in the yield higher, but the chemical yield per mu yield of chemical-induced male sterile lines breed higher; at the same time in Seed production, chemical-induced male sterile pollination system than cytoplasmic male sterile pollination seed production, and convenient and economical. In the field of test-mix utilization, the chemical-induced pollination system of male-sterile lines has a wide range of sources, free combination test, wide range of genetic variation and easy breeding of superior hybrid combinations.
