甘蓝型油菜新品系的抗裂角性筛选与相关性状分析
Hubei Agricultural Sciences（2019）
Abstract
甘蓝型油菜(Brassica napus L.)的裂角落粒严重影响油菜的产量和机械适收性.利用改进后的随机碰撞法对122份甘蓝型油菜的自交系和杂交组合进行抗裂角性评价,发现抗裂角指数(Shatter resistant index,SRI)大于0.60的品系占4.1％.分析抗裂角指数(SRI)与角果长、宽、果喙的相关性,发现抗裂角指数与角果长和果皮厚呈极显著正相关,且相关系数较高.结合种子的品质性状分析,共筛选了3份品质性状优良且抗裂角性强的甘蓝型油菜新品系早熟圣光168、E-7039和E-7089.
