强优势高油分杂交油菜品种油研924的选育（英文）

The Breeding of Hybrid Rape Variety Youyan 924 with Strong Heterosis and High Oil

国家863计划油菜项目"强优势甘蓝型油菜杂交种的创制与应用"要求其育成品种产量或产油量比对照品种增产10%以上,或含油量比对照提高3个百分点以上。杂交油菜品种油研924在长江中游两年区域试验中,平均产量和产油量分别达2 695.95 kg/hm2和1 264.35 kg/hm2,比同组参试品种平均产量和产油量分别增产5.22%和13.4%,比对照中油杂2号分别增产10.06%和23.68%,达到强优势杂交油菜品种标准;两年平均含油率为46.63%,比同组所有参试品种平均含油量高3.44个百分点,比中游杂2号平均含油量高5.14个百分点,生产试验含油量达49.21%。是一个强优势高油分品种。芥酸含量0.25%,硫甙含量20.27μmol/g(饼)。国家区试汇总资料总体评价为产油量高,丰产性好,品质达双低标准,抗倒性强,抗病性较好,熟期适中。

The rape project of ＂Development and Application of Cabbage Type Rape Hybrids with Strong Heterosis＂ which belongs to National 863 Program aimed to breed the rape variety whose rapeseed yield or oil yield increased more than 10% compared with check （CK） variety, or oil yield increased more than 3 percentage points compared with CK. In the regional trial in the middle react,es of the Yangtze River for two years, the average rapeseed yield and oil yield of Youyan 924 which is a hybrid rape variety respectively reached 2 695.95 and 1 264.35 kg/hm2, which respectively increased by 5.22% and 13.4% compared with those of the other test- ing varieties in the same group, and respectively increased by 10.06% and 23.68% compared with those of Zhongyouza 2 which belongs to CK, thus reaching the standard of hybrid rape variety with strong heterosis; the average oil percentage of the variety in the two years was 46.63%,which increased by 3.44 percentage points compared with that of all the other testing varieties in the same group, and in- creased by 5.14 percentage points compared with that of Zhongyouza 2, and the oil percentage of it in the production testing reached 49.21%. Thus Youyan 924 is a variety with strong heterosis and high oil, moreover, its contents of erucic acid and glucosinolate are 0,25% and 20.27 μmol/g, respectively. From the data aggregation of national regional trial, it has the advantages of high oil yield, high yielding ability, reaching the standards of low erucic acid and low glucosinolate, strong lodging re- sistance, good disease resistance aqd moderate mature period.
