黍稷种质资源粒色分类及其特性表现

黍稷种质资源的粒色是黍稷的主要农艺性状。粒色分类表明,黄粒种质比例最高,白粒种质次之。特性鉴定表明,白粒种质的优势最大,黄粒种质次之,说明白粒种质进化程度最高;但黄粒种质适应性和生育期又比白粒种质优势大,以至造成在分类中黄粒种质比例大于白粒种质的结果。红粒、褐粒、复色粒和灰粒种质也各自有自身的特色,在黍稷生产中发挥着不同的作用。

Seed Color Classification of Broomcorn Millet Germplasms and Their Performance Characteristics

Seed color of broomcorn millet germplasm is broomcorn millets＇main agronomic traits.Seed color classification shows that the particle has the highest percentage of germplasm,white grain germplasm followed.But feature identificationh indicates that white grain germplasm has the biggest advantage and yellow grain germplasm follows,which suggests that grain germplasm has the highest evolution degree,but yellow grain germplasm has bigger advantage in adaptability and growth period,than the white grain germplasm.It results bigger germplasm proportion in yellow grain germplasm than the white medium in classification.The red,brown,and grey multicolor grain germplasm also have their own characteristics and play their different roles in broomcorn millet production.
