研究了甘蓝型油菜杂交组合96F044D、96F045D、96F057D不育株及正常可育株根系伤流量、单位面积角果皮生产力和经济性状。万群体中不育株率以及3个杂交组合与常规油菜H045作对照的临界不育株率。结果表明不育株与正常可育株根系伤流量、单位面积角果皮生产力差异不显著,经济性状差异显著。相同不育系配制的杂交组合不育株率差异不显著,3个杂交组合的不育株率显著小于临界不育株率,杂种优势表现明显。
The root traumatic flow rate, pericarp per unit area productivity and economic traits of 96F044D, 96F045D, 96F057D sterile lines and normal fertile plants of hybrid rape were studied. The rate of sterile plants in the population, and the rate of the critical sterile plants in the three hybrid combinations as compared to the conventional R045. The results showed that there was no significant difference in root traumatic flow rate and per unit area of pericarp between sterile and normal fertile plants, and the economic traits were significantly different. The rate of sterile plants in the same sterile line was not significantly different. The rate of sterile plants in three hybrid combinations was significantly less than that of the critical sterile plants, and the heterosis showed obvious performance.
