Effects of Successive Selfing on Agronomic Traits of Brassica napus L.
摘要
Abstract
In this experiment, four Brassica napus L. lines as the test materials, the changes of major economic traits were studied after four years selfing, and the impact on Brassica napus L. by selfing were discussed . The results showed that selfing had significant impacts on the main economic characters of Brassica napus L. Plant height, branch height, effective branch, pods in the main inflorescence, pods of whole-plant and yield per plant were reduced as self-generations increased . The correlation coefficient between the major economic traits and selfing is from -0.979 to 0.289, and selfing with plant height, branch height, the number of pods of whole-plant, yield and other traits was a significant negative correlation, while the impact on seeds per pods and 1 000-seed-weight was smaller .关键词
