空间诱变创制不结球白菜晚抽薹新种质及新品种艳春的选育
Development of A New Late-bolting Germplasm and Breeding A New Cultivar Yanchun of Pak-choi by Using Space Mutation
摘要
Abstract
In order to develope a new pak-chi germplasm,and use it to breeding new cultivars.In this study,a new late bolting pak-chi germplasn SP67 was developed by space mutation,and a new cultivar Yanchun was breeded by using space mutation combined with traditional breeding methods.Morphological observations showed that Yanchun is erect,compact plant type,vigorous growth,glossy green outer leaves,wide-long green petiole,cold resistance and high disease resistance,late bolting and high quality.The average yield of Yanchun is 2 750 kg·666.7 m-2 at 35 days after seeding,and it's suitable for cultivation all over the country.Breeding of Yanchun showed that the mutagenic effect of pak-choi is very apparent through space mutation and can promote the improvement of agronomic characters and it's great significants to supply of pak-chi in spring.关键词
