New Wheat Variety'Kexing 3302':Detection and Analysis of High Quality and Yield Related Genes
摘要
Abstract
The aim is to understand the molecular genetic basis of high quality and high yield of new wheat variety'Kexing 3302'.'Kexing 3302'was used as the test material,and molecular markers related to quality,dwarf,growth and development,and disease resistance were used for detection.The results showed that'Kexing 3302'contained high molecular weight glutenin subunit combination Ax1G330E,Bx7+By8,Dx5+Dy10,low molecular weight glutenin Glu-A1a,non-1BL/1RS translocation line,which were the genetic basis of high quality;four dwarf genes Rht1,Rht2,Rht8 and Rht24,which were the genetic basis of lodging resistance and high and stable yield of the dwarf;three recessive vernalization genes Vrn-A1b,Vrn-B1b and Vrn-D1b as well as photopericyclic gene insensitivity gene Ppd-D1a,which were the genetic basis of cold resistance and wide adaptability;and QYm.njau-2D locus and anti-stripe rust gene Yr10,which were the genetic basis of high resistance to yellow Mosaic virus and stripe rust disease.The genes of quality,dwarf,growth and disease resistance in'Kexing 3302'were consistent with the phenotype of high quality and yield,disease resistance,laying a foundation for the efficient utilization of the excellent genes of'Kexing 3302'in molecular breeding.关键词
