摘　　要：为培育适宜贵州两熟制地区种植的早熟油菜品种,解决其油菜—水稻茬口矛盾,以高油分黄籽双低不育系YD3361A为母本,双低恢复系YD1021R为父本配制育成杂交油菜新品种宝油早12。该品种2011—2013年在贵州省早熟组(B组)油菜区域试验中的平均产量为147.58kg/667m2,比青油131(对照)增产2.31%;产油量平均为60.8kg/667m2,比青油131提高6.51%。2012—2013年在贵州省早熟组油菜生产试验中的平均产量为136.11kg/667m2,比青油131增产4.2%;产油量为60.51kg/667m2,比青油131提高8.83%。宝油早12全生育期189.69d,具有早熟、油分高、优质、抗逆性强等特点,于2013年9月通过贵州省农作物品种审定委员会审定(黔审油2014001号),并命名为宝油早12。Baoyouzao 12,a new hybrid rape variety was bred from YD3361A,a sterile line with yellow seeds,double low and high oil content ＆#215; YD 1021R, a double low restorer to solve the rotation contradiction between rape and rice for double cropping areas in Guizhou.The average yield and oil yield of Baoyouzao 12 were 147.58 kg/667m2 and 60.8 kg/667m2 ,2.31% and 6.51% higher than Qingyou 131 （CK）separately in the early group （B group）of Guizhou rape regional tests during 2011-2013 and the average yield and oil yield of Baoyouzao 12 were 136.11 kg/667m2and 60.51 kg/667m2,4.2% and 8.83%higher than Qingyou 1 3 1 （CK ） separately in the early group of Guizhou rape productive test during 2012-2013.Baoyouzao 12 with 189.69 d growth period,early maturity,high oil content,good quality and strong stress resistance was approved by Guizhou Crops Variety Examination Committee in September,2013.
