以粳稻魔王谷和籼稻CO39配组衍生的280个重组自交系为材料, 2015年和2016年对其粒形、剑叶形态、株高性状进行了相关性分析和QTL检测。剑叶长分别与粒厚和株高存在极显著负相关和正相关,剑叶宽与粒宽存在极显著正相关。检测到17个粒形QTL,分布于第1、第2、第3、第4、第5、第6、第7、第9和第10染色体上,贡献率为3.51%~48.65%;其中,第3染色体RM6080-RM6283区间对粒长和千粒重兼具显著作用,第5染色体RM8211-RM3381区间同时影响粒宽和粒厚。检测到12个控制剑叶形态性状的QTL,分布于第1、第3、第4、第6、第7和第9染色体上,贡献率为4.26%~38.40%;有5个多效QTL区间,其中,第4染色体RM252-SFP4_6区间同时...

In this study, 280 recombinant inbred lines (RIL) derived from a cross between japonica rice Mowanggu and indica CO39 were used to analyse correlations and detect QTLs for grain shape, flag leaf morphology and plant height in 2015 and 2016. The flag leaf length was significantly negatively and positively correlated with grain thickness and plant height, respectively. And there was a significant positive correlation between flag leaf width and grain width. Here, we identified 17 QTLs for grain shape traits distributed on chromosomes 1, 2, 3, 4, ...
