摘要
双低油菜湘油11号于1987年通过品种审定,该品种种子含油量40%以上,油中芥酸含量0.47%,饼中硫代葡萄糖甙含量0.24%,种子产量比常规推广品种增产10%以上。抗病性较强,全生育期210～220d。湘油11号采用杂交育种法育成,在亲本选择上除注意品质性状和产量性状外,还注意到品种对光温反应特性,并设计出改良五圈制育种程序进行选育和鉴定。
Double low rapeseed Xiangyou No.11(Brassica napus) was licenced)in 1987. Oil content in the c.v. seed is 40%. Erucic acid content in the oil-is 0.47%.Glucosinolate content in the meal is 0.24%. The increase of the seedyield is over 10% compared with recommended conventional rapeseed varities.Its resistance to desease is better. The duration from seedling to ripening is 210~220 days. Attention has been paid to the selection of parents according to their res-ponse to temperature and daylength beside their quality and yield charecteris-tics, A modified 5-nursery breeding program has been designed.
