耐热青菜杂交新品种‘闵青101’的选育

摘要

利用国内优良的种质资源,通过有性杂交技术和系统选育方法,选育出优良的雄性不育系03-11A和自交系07-3-4-1,通过组合的选配,培育出青菜新品种‘闵青101’.‘闵青101’耐热、抗病,适宜夏秋季栽培,特别适合夏季生产,播种后15～40 d可采收,30 d平均产量可达22.5 t/hm2.%Minqing 101' ,a new pak-choi variety,was bred by hybridizing the male sterility line 03-11A with the inbred line 07-3-4-1 which were selected by sexual hybridization and systematic breeding of superior domestic germplasm resources. The experimental results showed that this variety was tolerant to heat and resistant to disease and was suitable for planting in both summer and autumnCespecial-ly in summer).It could be harvested at 15~40 days after seeding and its average yield could be up to 22.5 t/hm2 at 30 days after seeding.
