摘要 1995年度8个点的试验结果,YD16平均单产343545kg/hm2,比对照种(中油821)增产1728%,增产极显著;田间菌核病株率平均为1889%,病指936,比对照分别降2178%和3777%。YD16在分枝习性、结果密度及角长粒多等方面。 In 1994, new strain YD16 from intergeneric hybridization between B.napus and Capsella bursa pastoris(L) Medica had been grown in eight regions. Results showed that the average yield of YD16 in eight plots was 3435 45 kg/hm 2, which was 17 28% higher than the comparison Zhong You 821. The seed yield of YD16 increased significantly. Investigation made in fields showed that the average rate of stem rot affected plants of YD16 was 18 89% and disease index was 9 36. The rate and disease index were reduced by 21 78% and 37 77% than the comparison, respectively. Compared with the comparison, the branch characteristics, pod density, pod length and seeds per pod of YD16 were improved greatly.
