QTL analysis of chlorophyll contents in rice under different water supply
To make an genetic analysis of chlorophyll contents inheritance under different water supply, the parents and 247 RILs were respectively planted under water stress and non-water stress, and chlorophyll contents were continually measured on the same leaf at seedling and after anthesis, respectively....

| Summary: | To make an genetic analysis of chlorophyll contents inheritance under different water supply, the parents and 247 RILs were respectively planted under water stress and non-water stress, and chlorophyll contents were continually measured on the same leaf at seedling and after anthesis, respectively. Under different water supply, a total of 13 QTL for chlorophyll contents was detected to have significant additive effects at different growth stages. Among the QTL detected, 6 QTL were detected under water stress, explaining 4.74% to 19.86% of the phenotypic variation, 7 QTL detected under paddy field, explaining 4.92% to 14.02% of the phenotypic variation. No QTL was detected in the same interval under water stress and non-water stress. Meanwhile, 7 QTL were detected for stress sensitive index, of which 2 QTL, qkhChl-2a and qkhChl-6, explained 25.29% and 38.70% of phenotypic variations at the first measurement of seedling and anthesis. The alleles for increasing trait values were from Zhenshan 97B. |
