摘要
针对当前慈溪蚕豆田间花色、株型、荚型和豆粒大小等性状不一致、种质混杂、种性退化严重、产量下降的现状,该研究征集慈溪大白蚕种质资源,通过隔离繁育、单株选择等方法进行提纯复壮.结果表明,开展慈溪大白蚕选育的本 2 株系紫花紫茎、种皮青白,百粒重为 134.0 g,667 m2 产量为 223.2 kg.在植株形态、结荚特性、籽粒大小和产量上基本恢复了该品种的原有性状.品种提纯复壮工作取得了预期的成效.
Abstract
In view of the current situation of inconsistent flower color,plant type,pod type and bean grain size in the field,mixed germplasm,serious degradation of germplasm and declining yield of Cixi broad bean in the field,we collected germplasm resources of Cixi Dabaican and purified and rejuvenated them through isolated breeding and single plant selection.The results showed that the line of Ben 2 of Cixi Dabaican had purple stems and green white seed coats with the 100-grain weight of 134.0 g,and the yield of 667 m2 was 223.2 kg.The original traits of this variety were basically restored in terms of plant morphology,pod-setting characteristics,grain size and yield.The work of purification and rejuvenation of varieties has achieved the expected results.
