摘要
【目的】解决圆叶型菜心核基因雄性不育系的选育和利用难题。【方法】以复等位基因遗传的柳叶型菜心核基因雄性不育系"GMS201"为不育源,在测交鉴定基因型的基础上,采用回交法转育性状,向圆叶型菜心品系"奇2"中转育核不育基因。【结果】育成了不育株率和不育度均为100%且园艺学性状与"奇2"相近的新核不育系"GMS202";新不育系克服了不育源材料"GMS201"花蕾条纹状白化和结籽不良的缺陷,并用其配制出2个强优势组合。【结论】用本试验设计的核不育系转育方案,可以实现菜心雄性不育性和其他园艺学性状的同时转育。
【Objective】 The study was done in order to solve the problems in the transfer and utilization of genic male sterile line in Flowering Chinese cabbage.【Method】 A multiple allele inherited genic male sterile line of willow-leaf Flowering Chinese cabbage,GMS201,was used as source of male sterility,and a round-leaf Flowering Chinese cabbage,"Qi 2",was used as target strain.Backcross was applied to transfer the male sterile gene based on genotype identification though test-crossing.【Result】 A round-leaf genic ma...
