Purification and rejuvenation technology of broad bean variety Cixi Dabaican
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.
