摘要

Youyan 817, a hybrid rape variety with 0. 2% erucic acid content and 28. 35μmol glucosinolates/(g/cake) , bred from 850A(a recessive nucleic male sterile line with yellow seed, low erucic acid content and low glucosinolates content) X HF16-1400 (a restorer line with low erucic acid content and low glucosinolates content) was approved by Zhengjiang Crops Variety Examination Committee and State Crops Variety Examination Committee in 2009 and 2010 respectively. The average yield, oil yield and oil content of Youyan 817 in regional tests of the upper reaches of Yangtze River reached 174. 62 kg/667m2, 79. 2 kg/667m2 and 45. 32%, 6.6%, 9. 34% and 1% higher than Youyan 10 respectively.%以黄籽双低隐性核不育系850A与双低恢复系HF16-1400为亲本配制了黄籽双低高油分杂交油菜油研817.该组合在长江上游区域试验中,平均产量和产油量分别达174.62 kg/667m2和79.2kg/667m2,较对照(油研10号)分别增产6.6％和9.34％;平均含油率为45.32％,比对照(油研10号)高1百分点,是油研10号作对照6年来第1个含油率稳定超过其的品种;芥酸含量0.2％,硫甙含量28.35μmol/g饼.该组合于2009年12月和2010年分别通过浙江省品种审定委员会审定和国家品种审定委员会审定.
