在生态条件不同的15个试点对9个白菜型冬油菜品种(系)的抗寒性、产量、经济性状、生育期表现等进行了研究。结果为白菜型冬油菜在北方地区越冬率最高达到95.0%,生长发育正常,且表现出良好的适应性和经济性状,产量为167.9~198.5kg/亩,生育期244~295天。试验结果表明在北方地区发展白菜型冬油菜生产是可行的。经过本次试验为北方地区筛选出了越冬率高,综合性状优良,生育期适宜的陇油6号、陇油7号、陇油8号、陇油9号优良品种(品系)。
The cold resistance, yield, economic traits and growth period of 9 cabbage-type winter rapeseed cultivars (lines) were studied in 15 experimental plots with different ecological conditions. The results showed that the overwintering rate of cabbage-type winter rape reached 95.0% in the north, with normal growth and development, and showed good adaptability and economic traits. The yield was 167.9 ~ 198.5kg / mu and the growth period was 244 ~ 295 days. The results show that it is feasible to develop cabbage-type winter rapeseed production in northern China. After this experiment, we selected the excellent varieties (lines) of Longyou No.6, Longyou No.7, Longyou No.8 and Longyou No.9 with the overwintering rate, good comprehensive characters and suitable growth period for the northern area.
