中国黄淮海地区小麦品种抗寒性及其与VRN1基因型的关系
Cold Hardiness and Its Relationship with theVRN1Genotypes in Wheat Varie-ties in the Yellow-Huai-Hai River Valley Region of China
摘要
Abstract
Winter freezing injury is one of the major natural disasters in wheat production. The effect ofVRN1genes on cold hardness was analyzed with phenotypic data and the allelic variations of VRN-A1,VRN-B1,VRN-D1in 71 wheat varieties grown in Yellow-Huai-Hai River Valley region. The results indicated that the cold hardiness of wheat was correlated with other stress toler-ances, and strong cold hardiness was found in most varieties showing good salinity tolerance, drought tolerance or water-saving fea-ture in production and the National Variety Regional Trial. VRN1 is a critical locus in the genetic network of wheat cold hardiness. The presence of the dominant geneVRN1was often accompanied with a significant decrease in cold hardiness, and weak cold hardi-ness was usually detected in the varieties with two or threeVRN1 genes. Coexistence of recessive genes vrn-A1,vrn-B1, andvrn-D1 was found to be an indispensable prerequisite for strong cold hardiness. Therefore, thevrn-A1vrn-B1vrn-D1 genotype is suggested in wheat production and variety improvement in the northern part of Yellow-Huai-Hai River Valley region of China.关键词
