Study on the full sterile line and F1 seed production technique of Huyouza No.1(Brassica napus L.) with good quality and high yield

摘要

The production and purity of full sterile line Hu118A in the different isolation environments and the yield of commercial F1 hybrid seedin different ratios of parental lines were studied. It showed that the production and purity of full sterile line Hu1 18A was 770.4kg/ha and 98% in greenhouse with honeybee as the pollination medium, and that planting ratios 1:3 and 1:4 were found to give similar results and produced significantly higher seed yields than the ratio of 1:2, 1:5 and 1:6. So the high yield of F1 seeds Huyouza No. 1 could be obtained in high purity of full sterile line and planting ratio 1:4 or1:3.
