Study on Breeding of Double low Hybrid Kenyou 3 in spring Brassica napus L.

垦油 3号是利用细胞质雄性不育技术育成的甘蓝型双低春油菜三系杂交种。主要优点为高产、优质、抗逆性较强。1 995～ 1 998年产量鉴定及区域试验平均单产 2 1 33.6kg/hm2 ,比对照品种垦油 1号增产 1 6.5%,居参试品种第一位 ,1 999年参加省生产示范试验比垦油 1号增产 2 1 .2 %。较抗菌核病和其它病害 ,芥酸含量 0 .88%,硫甙含量 2 4 .8μmol/g,粗脂肪含量 43%以上。

Kenyou No.3(CMS040A×R32)was a three line hybrid which bred with cytoplasmic male sterile. Kenyou No.3 was vigorous in heterosis high yeild, high quality, tolerance to Scleroinia scleroliorum with 0.88% of erucic acid in its oil, 24.8μmol/g of glucosinolate content in its meal, above 43% of oil content. It was tested in Heilongjiang provincial district test in 1995~1998. The average yeild was 2133.6kg/hm 2。 It was 16.5% higher than check hybrid Kenyou No. 1. It was the first in all tested hybrids. It was tested in Heilongjiang provincial productive demanstration in 1999. The yeild was 21.2% higher than check hybrid Kenyou No.1.
