Fig. 1From: Natural variation at qHd1 affects heading date acceleration at high temperatures with pleiotropism for yield traits in riceEffects of qHd1 on heading date (a) and 1000-grain weight (b) detected in the multiple sowing-date experiment. I, III and IV in (b) refer to the trials with sowing date of 28 Apr, 20 May, and 15 Jun in (a), respectively. In all the trials, 50 lines of each genotype in the CJ1 and CJ2 populations were tested. Values are represented as means ±SD. NIL-ZS97 and NIL-MY46 are near isogenic lines with Zhenshan 97 and Milyang 46 homozygous genotypes at qHd1, respectivelyBack to article page
