| 摘 要： | 对油研系列品种油菜菌核病的抗(耐)性鉴定结果表明,4个油研品种的平均发病株率、平均病情指数分别为 24．02％、11．83,平均产量为123．10kg／667m2。相关分析表明,初花至终花的经历天数与田间发病株率、病情指数均呈显著正相关,发病株率与病情指数呈极显著正相关,田间发病株率、病情指数与产量间相关均不显著。

| Abstract: | The results show that the average disease incidence rate and disease index of four Youyan varieties are 24. 02% and 11. 83 respectively, the difference is not significant compared with those of Zhongyou 821, Rongyou 4 and Qinyou 7. The average yield of four Youyan varieties is 123. 10 kg/667m2 , which is higher than the yield of CK and Qinyou 7 and the yield of Youyan 9 and Youyan 11 is significantly higher than the yield of CK. There is a significant positive correlation between the days from first flower to finishing flower stage and disease incidence rate, disease index and a very significant positive correlation between disease rate and disease index. There is no significant correlation between yield and disease rate, disease index. |
