Abstract

Abstract:

To adapt to the demand about green high quality and efficient cultivar breeding of wheat, and industry improving for Ningxia Hui Autonomous Region, using 248 F_2∶5 pedigrees of Ningchun No.4 × Hedong black wheat as materials, their genetic map was constructed, and grain protein traits QTL (quantitative trait locus) were analyzed, so as to provide breeding intermediate materials and QTL for genetic improvement of wheat protein traits in this area. The results showed that a molecular genetic map of 21 chromosomes in wheat was constructed using 197 SSR (simple sequence repeats) markers, the total length was 2 342.63 cM with an average interval distance of 11.89 cM. The distribution of quality traits in F_2∶5 pedigrees were significantly separated. Average values of crude protein content (14.49%) and wet gluten content (30.96%) were between those of high-parent and low-parent, the average value of stabilization time (10.86 min) was over the high parents. The proportion of over mid-parent was 50.81%, 77.82% and 50.00% in crude protein content, stabilization time and wet gluten content, respectively; Proportions of ultra-high parents was 21.77%, 59.27% and 22.98%, respectively. There was significantly positive correlation among three grain protein trait indices. 36 QTL loci of grain protein traits were explored by 22 SSR markers, there were 14 QTL, 6 QTL and 16 QTL of crude protein content, stabilization time and wet gluten content, respectively, those involved in chromosomes 1A, 2A, 3A, 5A, 7A, 1B, 2B, 6B, 1D, 2D, 3D, 4D, 5D, 6D and 7D, maximum logarithm of odds (LOD) score of these 36 QTL was 14.9, the contribution rates to phenotype were from 3% to 6%, their additive effects were from -1.71 to 1.17, and QTL enrichment regions of grain protein traits existed in 11 marker loci.

Key words: wheat (Triticum aestivum L.), pedigree, genetic map, protein trait, quantitative trait locus
