Title	Identification of quantitative trait loci (QTLs) controlling heading time in the population generated from a cross between Oriental and Occidental barley cultivars ( Hordeum vulgare L.)

Abstract	This study was conducted to identify QTLs controlling heading time of barley. A total of 89 recombinant inbred lines (RILs) generated from a cross between the Oriental-type winter cultivar Azumamugi and the Occidental-type spring cultivar Kanto Nakate Gold were examined. Two field experiments consisting of one spring sowing and one autumn sowing and a greenhouse experiment under 24 h illumination were conducted. Two genes for the spring habit and 5 QTLs controlling heading time were identified. The genes for the spring habit, sgh1 and Sgh2 , were located on chromosomes 4HL and 5HL, respectively; 4 QTLs were mapped close to the heading time genes identified in the previous studies on chromosomes 1HL, 2HS, 2HL and 7HS; and one was a new QTL detected on chromosome 7H
