饲用皮燕麦种间杂交育种研究初报

Primary investigation of hybridization breeding research of several oats

采用成对杂交法,对几种皮燕麦的生育期、产草量、种子产量、杂交成功率、杂交结实率、杂交后种子变化等进行了比较分析,初步确定"早熟低产籽×晚熟高产籽"中巴燕3号×青永久450,青永久144×青永久089较为理想的组合;"低产籽高产草×高产籽低产草"青永久178×青永久450和青海甜燕麦×青海444较为理想,青海444×青引2号较为合理。

The several oats were crossbreed by applying biparental cross. The growth stage,the grass yield,the seed yield,the success rate of crossbreed,the ripening rate of crossbreed and the seed character were compared to their parent strain. It turned out that Avena sativa cv. Bayan No. 3 × Avena sativa cv. Qingyongjiu 450 and Avena sativa cv.Qingyongjiu 144 × Avena sativa cv. Qingyongjiu 089 is adaptive in 'Low seed yield and prematurity × High seed yield and the late maturity'grouping; Avena sativa cv. Qingyongjiu 178 × Avena sativa cv. Qingyongjiu 450,Avena sativa L.cv. Qinghai × Avena sativa L. cv. Qinghai No. 444 and Avena sativa L. cv. Qinghai No. 444 × Avena sativa L. cv.Qingyin No. 2 is adaptive in 'Low seed yield and high grass yield × High seed yield and low grass yield'grouping.
