BACKGROUND Grain yield is a key economic driver of successful wheat production. Due to its complex nature, little is known regarding its genetic control. The goal of this study was to identify important quantitative trait loci (QTL) directly and indirectly affecting grain yield using doubled haploid lines derived from a cross between Hanxuan 10 and Lumai 14. METHODOLOGY/PRINCIPAL FINDINGS Ten yield-associated traits, including yield per plant (YP), number of spikes per plant (NSP), number of… CONTINUE READING

Ten yield - associated traits , including yield per plant ( YP ) , number of spikes per plant ( NSP ) , number of grains per spike ( NGS ) , one - thousand grain weight ( TGW ) , total number of spikelets per spike ( TNSS ) , number of sterile spikelets per spike ( NSSS ) , proportion of fertile spikelets per spike ( PFSS ) , spike length ( SL ) , density of spikelets per spike ( DSS ) and plant height ( PH ) , were assessed across 14 ( for YP ) to 23 ( for TGW ) year × location × water regime environments in China .

Quantitative Trait LociAnatomic structure is physical part ofChromosomes
Twelve ( YP ) to 33 ( PH ) QTLs were identified on all 21 chromosomes except 6D. QTLs were more frequently observed on chromosomes 1B , 2B , 2D , 5A and 6B , and were concentrated in a few regions on individual chromosomes , exemplified by three striking yield - related QTL clusters on chromosomes 2B , 1B and 4B that explained the correlations between YP and other traits .
