为大粒高含油油菜的育种提供参考,本实验以12个不同千粒重油菜种子为研究对象,按千粒重大小分成小粒,常规和大粒三个组,研究千粒重、皮壳率、含油量、发芽势与发芽率和生理生化指标,并研究不同性状之间的相关性。结果发现油菜千粒重与皮壳率表现出极显著的负相关关系,与含油量和SOD活性存在正相关,关系极显著;含油量与皮壳率和MDA存在显著负相关关系,与SOD存在极显著正相关关系;MDA与SOD之间存在极显著的负相关关系。千粒重最高的是12号,其含油量和SOD活性最高,MDA和皮壳率最低。大粒黄籽油菜表现出皮壳率和MDA含量低,含油量、POD和SOD活性高。油菜千粒重越大,皮壳率越低,含油量越高;黄籽油菜种...

To pro vide reference for breeding and popularization of large yellow seed rapeseed, we took 12 different 1 000-grain weight rapeseed seeds as research object, which were divided into small grain, regular and large grain according to the size of 1 000-grain weight. Their 1 000-grain weight, shell rate, oil content, germination potential and germination rate and physiological and biochemical indexes were studied, and study the correlation between different traits. The results showed that a significant negative correlation between the ratio of oily husk and 1 000-grain weight, and it was positiv...
