利用染色体片段代换系定位水稻叶片形态性状QTL
QTL Mapping for Leaf Morphological Traits of Rice Using Chromosome Seg-ment Substitution Lines
摘要
Abstract
Leaf morphology is an important component of ideal plant architecture in rice. Therefore, identification of genes asso-ciated with leaf morphologic traits is helpful to shape rice ideal architecture and reach the aim of super high-yield. A set of chro-mosome segment substitution lines (CSSLs) derived from Guanglu'ai 4 (recipient) and Nipponbare (donor) were employed to detect quantitative trait loci (QTL) for the length and width of top three leaves (flag leaf, the second and third leaf from top). We also examined the correlation between the leaf traits and grain yield per plant, indicating that except for flag leaf width, other leaf traits were significantly and positively correlated with grain yield per plant. One-way ANOVA and Dunnett's test were used to detect QTLs related to size of rice top three leaves. Thirteen and seven QTLs, for leaf length and width, respectively, were identi-fied. Among them, eight and four QTLs had positive effects, respectively. Identification of these QTLs provides useful informa-tion for improving rice leaf morphologic traits.关键词
