초록
Association analysis was conducted to identify quantitative trait loci (QTL) of yield potential traits, days to heading date, culm length, spike length and kernels per spike, in genetic mapping population (94 F10 recombinant inbred line) produced from a cross between two Korean wheat cultivars, Taejoong with a large kernel number line carried with the longer spike length and higher kernel number per spike and Keumkang. Yield potential traits, days to heading date, culm length, spike length and kernels per spike were evaluated in 2017 and 2018 in upland condition. Days to heading date was biased late heading date (skewness=-0.3), and spike length was biased short spike length (skewness=0.7). A genetic map was constructed with 57 microsatellite marker loci and two QTLs were detected for spike length. The first QTL on chromosome 2A, qSL-1 was detected by Xcfd5 and Xpsp3050 and explained 20.7% of phenotypic variation. The second QTL on chromosome 5B, qSL-2 was detected by Xwmc656 and Xwmc415 and explained 40.8% of phenotypic variation. Those QTLs were applied to validate relationship between genotypes of QTL and 29 Korean wheat cultivars cultivated for nine years, from 2010 to 2018. Korean wheat cultivars were classified into 6 types according to the genotypes of Xcfd5-Xpsp3050 and Xwmc656-Xwmc415. The same genotypes to Keumkang showed higher frequency and short spike length than that of Taejoong in Korean wheat cultivars.
Abstract
Association analysis was conducted to identify quantitative trait loci (QTL) of yield potential traits, days to heading date, culm length, spike length and kernels per spike, in genetic mapping population (94 F10 recombinant inbred line) produced from a cross between two Korean wheat cultivars, Taejoong with a large kernel number line carried with the longer spike length and higher kernel number per spike and Keumkang. Yield potential traits, days to heading date, culm length, spike length and kernels per spike were evaluated in 2017 and 2018 in upland condition. Days to heading date was biased late heading date (skewness=-0.3), and spike length was biased short spike length (skewness=0.7). A genetic map was constructed with 57 microsatellite marker loci and two QTLs were detected for spike length. The first QTL on chromosome 2A, qSL-1 was detected by Xcfd5 and Xpsp3050 and explained 20.7% of phenotypic variation. The second QTL on chromosome 5B, qSL-2 was detected by Xwmc656 and Xwmc415 and explained 40.8% of phenotypic variation. Those QTLs were applied to validate relationship between genotypes of QTL and 29 Korean wheat cultivars cultivated for nine years, from 2010 to 2018. Korean wheat cultivars were classified into 6 types according to the genotypes of Xcfd5-Xpsp3050 and Xwmc656-Xwmc415. The same genotypes to Keumkang showed higher frequency and short spike length than that of Taejoong in Korean wheat cultivars.
