甘蓝型油菜隐性上位互作核不育双低杂交种皖油14的选育

Breeding of Wanyou 14, a recessive epistatically genic male sterile hybrid rapeseed (Brassica napus) with double low

皖油 14(原C0 2 2 )是利用隐性上位互作核不育育成的甘蓝型油菜杂交种 ,具有丰产、稳产、优质 (高含油、低芥酸、低硫甙 )、抗 (耐 )病等特性。安徽省区试平均产量 2 6 6 1kg/hm2 ,比对照秦油 2号增产 7.2 % ,比对照中油82 1增产 2 2 .9%。全国 (长江下游区 )区试平均产量 2 149kg/hm2 ,比对照中油 82 1增产 12 .6 %。抗 (耐 )病性优于秦油 2号和中油 82 1。芥酸含量为 0 .36 % ,硫甙含量为 31.2 μmol/g ,含油量达 44 .3 %。

Wanyou 14, a recessive epistatic GMS hybrid in Brassica napus, collected high yield, stable yield, high quality (high oil content and double low) and disease resistance together. It showed yield of 2 661kg/hm2 which outyielded the control Qinyou No.2 by 7.2% and Zhongyou 821 by 22.9% in Regional Test of Anhui pro vince during 1994-1996, and yield of 2 149kg/hm2 which outyielded the control Zhongyou 821 by 12.6% in National Regional Test (downstream region of Yangzi River) during 1997-1999. Wanyou 14 had higher disease resistance than Qinyou No.2 and Zhongyou 821. The cultivar possessed good quality with low erucic acid content of 0.36%, low glucosinolate content of 31.2μmol/g meal and high oil content of 44.3%.
