Abstract: The Heterosis Utilization is the important method of raising the rapeseed production level. In order to improve the rape output and oil yield, Jiangsu Institute of Agricultural Science in the Lixiahe District used rapeseed cytoplasm male-sterile line, success to breed the new hybrid rapeseed variety, Yangyou NO.8. In the multi-site regional trail of Jiangsu provincial hybrid rapeseed, its performance prominent: The yield is high, the general output may reach 200kg/667m2; stability is good, the output amplitude is small during several years in the multi-site regional trail; Its quality is superior, conforms to the national double low standard; The resistance is stronger. It Is an outstanding hybrid rape new variety. In order to promote the variety application, correlation high production research was conducted, and propose the concrete cultivation measure.
