摘要
以"北京细香葱"采种田中发现的香葱不育株为不育源进行开放授粉,最后获得5个优良的单株种球,按株系播种。从不育株率高的株系中选择优良植株与对应的父本系进行混合授粉,回交转育连续5代,得到36A,其不育株率和不育度为100%,相应的父本称为36B。不育系36A表现出抽薹晚,抗病性强。以36A为母本配制的杂交组合2016-2017年平均每667 m^2产量为2434.6 kg,比对照品种增产15.93%,有效的解决了香葱制种问题,为创新香葱种质资源奠定了基础。
With the male sterile plants of‘Beijing Chives’as infertility source for open pollination,five excellent individual seed balls were obtained and planted according to the plant strains.Then excellent plants with high sterile plant rate were selected and mixed pollination with the corresponding male parent.The sterile plant rate and sterility of 36 A were 100% after 5 successive generations of backcrossing,which showed late bolting and strong disease resistance,and the corresponding male parent was called 36 B.The average yield of the hybrid combination prepared with 36 A as female parent was 2434.6 kg per 667 m2 from 2016—2017,15.93% higher than that of the control cultivars,which effectively solved the problem of chive seed production and laid a foundation for innovation of chive germplasm resources.
