甘蓝型优质无花瓣油菜NF001的发现与选育

Discovery and Breeding of NF001,a Quality Rape Line with Apetalous(B.napus L.)

1998年春在有性杂交组合940×中双821Y的F2群体中发现缺辩植株，之后通过兄妹交、自交连续进行了4代的定向选择，育成了无辩性状稳定的双低甘蓝型油菜常规优质品系NF001。其群体无辩基因外显率达100％，全无辩花率达98．6％～100％，无辩度达99．6％～100％，芥酸含量1％左右，硫代葡萄糖甙含量25．3～28．6μmol／g饼，含油量40％左右，蛋白质35．8％～37．1％，是一个具有特异性状的优异种质资源，具有较高的潜在育种价值。

NF001 ,the quality rape line with apetalous, was bred from the sibling cross and self cross of the plants with lack petal found in F1 population of 940 × Zhongshuang 821Y after derective selection of four generations. Its apetalous plant rate, apetalous rate and apetalous degree are up to 100%, 98.6%- 100% and 99. 6%~100% respectively and the contents of erucic acid, glucosinolate, oil and protein are 1%, 25.3-28.6μmol/g, 40% and 35.8% -37.1% separately, which indicates that the line is the excellent germplasm resource with special characters in rape breeding.
