早熟与中熟油菜品种的性状差异比较

Comparison of the Characters of Early and Middle Maturity Rape Varieties

为了明确早熟与中熟油菜品种农艺和产量性状的差异,利用参加国家油菜品种区域试验的早熟和中熟品种的区试结果,对早熟与中熟油菜品种间的各性状进行差异分析比较。结果显示:在农艺性状方面,早熟与中熟油菜品种的生育期、株高、一次有效分枝数存在极显著的差异,其中生育期的差异最明显,有效分枝部位和主花序长差异不显著;在产量性状上,主花序角果数、单株有效角果数、千粒重存在极显著的差异,其中主花序角果数的差异最显著,每角粒数差异不显著;在抗逆性方面两者差异不显著;在品质性状方面,硫苷和含油量存在显著的差异性,介酸含量差异不显著。

The results of the regional area test of early and middle maturity rape varieties were used to clarify the character differences of early maturity and middle maturity rape varieties. Results show that there were significant differences in growth period,plant height,the number of effective branch of the first time between early and middle maturity rape varieties. The difference of the growth period was the most significant. While the difference between effective branching position,main inflorescence length were not significant. About the yield traits,there were significant differences in the number of main inflorescence pods,the number of effective pods per plant and thousand grains weight between rape varieties with different maturity stage. The difference of the number of main inflorescence pods were the most significant,and the difference in grain number per pod was not significant. There was no significant difference in resistance traits between the two group varieties. There were significant differences in glucosinolate and oil content,but the difference in medium acid content was not significant.
