Genetic Background and Breeding Analysis of a New Wheat Variety Hemai317
摘要
Abstract
To breed new high-yield,stab-yielding,disease-resistant and lodging resistant wheat(Triti-cum aestivum L.)varieties that meet market demands for production application,the high-yield and widely adaptable variety Jimai22 was used as the female parent,and the large-spike and lodging resist-ant variety Zhoumai24 was used as the male parent for hybridizing and matching.By combining germ-plasm resource evaluation,field generation selection and genetic background analysis,the gene re-combination and aggregation that controlled excellent traits were strengthened.The new wheat variety Hemai317 was bred by using the selection method of'focusing on high-yield,disease resistance and lodging resistance as the main goals,balancing other secondary goals,and eliminating inferior varie-ties to preserve the superior ones',through pedigree method and single-spike-spike row-spike line op-timization selection method.It participated in the high-yield group regional trials and production trials of wheat varieties in Shandong Province from 2019 to 2022.The genetic background of Hemai317 was analyzed by using pedigree relationship and FISH.The results showed that the average yield of the 2-year regional trial was 8 658.0 kg/hm2,which was 2.3％higher than that of the control Jimai22.The average yield of the production test was 9 853.5 kg/hm2,which was 6.6％higher than that of the control Jimai22.The disease resistance was identified as highly resistant to stripe rust and powdery mildew,and moderately resistant to sheath blight.Hemai317 effectively integrated the important bloodlines of wheat varieties from the two major regions of Shandong and He'nan,and combined nu-merous excellent traits such as high yield and wide adaptability,disease resistance,lodging resist-ance,and large and numerous ears.It was suitable for cultivation in high-yield plots in Shandong Province.Meanwhile,compared with Jimai22,there were differences in 9 signal loci between He-mai317 and Jimai22,which showed rich genetic diversity at the chromosomal level.关键词
