多花多荚型高产蚕豆品种的选育

Breeding of Iaba bean of bigh yielding variety

蚕豆落花落荚十分严重，成荚率低，严重地制约蚕豆产量的提高。为了解决花荚脱落，利用国际干旱地区农业研究中心（ＩＣＡＲＤＡ）提供的花梗内具有独立维管束供应的蚕豆种质资源为亲本，通过杂交育种，对浙江省的蚕豆地方品种加以改良，经过７年的研究，于１９９３年选育成花梗内具有独立维管束供应的蚕豆新品系２个，表现荚多、粒多、粒重、单株产量高，明显优于浙江省地方品种。

Severe blossom and pod drop in faba bean and low pod sctting ratea seriously influence yicldixicrease pcr unit. A study on solving the problem of blossom and pod drop and irnproving Zhejiang's l0-cal varicties was made by using ICARDA'S Independent Vascular Supply type of faba bean gemplasm re-sourccs throjugh oross breeding. The best two Iines of IVS were developed at Zhejiang Academy of Agri-cultural Sciences in Hangzliou in 1 993 through seven years research. The numbcrs of pods and seeds perplant, 100-seed weight (g) , and seed yield per plant (g) were more than thosc of Zhejiang's localvanetles.
