两个高产抗逆小麦新品种的KASP标记检测与分析
Detection and Analysis of KASP Markers for Two New High-yielding and Stress-resistant Wheat Varieties
摘要
Abstract
To further understand the genetic composition of important traits of'Luomai 76'and'Yanfeng 168',KASP markers were used to detect the functional genes related to plant height,adaptability,grain traits,stress resistance and quality.The results showed that both'Luomai 76'and'Yanfeng 168'carried the dwarfing allele Rht-D1b.'Luomai 76'combined three photoperiod-insen-sitive early-flowering genotypes Ppd-A1a,Ppd-B1a andPpd-D1a,while'Yanfeng 168'wasPpd-B1a,which had strong adaptability.Both varieties had high thousand-grain weight and good commercial quality.'Luomai 76'and'Yanfeng 168'combined 11 and 13 minor genes for high grain quality,re-spectively.Both varieties exhibited strong stress resistance.'Luomai 76'carried the major gene PHS-646 for resistance to preharvest sprouting,as well as three minor drought-resistance genes 1-feh-w3,CWI-4A and CWI-5D.'Yanfeng 168'carried two minor drought-resistant genes CWI-4A and CWI-5D.Both varieties exhibited a favorable quality profile.'Luomai 76'carried the high-molecular-weight glutenin subunit Glu-A1 genotype,whereas'Yanfeng 168'carried the strong-gluten genotypes containing Glu-A1 and Glu-D1.Both'Luomai 76'and'Yanfeng 168'carried the hard endosperm allele Pinb-D1b.Both varieties carried the high-yellow-pigment alleles:Ppo-A1a,TaZds-A1b,Psy-A1a,Psy-D1g and TaZds-D1a,which had high nutritional value.The identification of these favorable alleles in'Luomai 76'and'Yanfeng 168'provides a theoretical basis for further utilization and genet-ic improvement.关键词
