摘要: seedling-vigor is important for crop establishment. There have been reported quantitative trait locus (QTL) analyses on related morphological traits. However, physiological understanding of these detected QTLs rather limited. In this study, we employed a recombinant inbred population to detect traits and seedling-vigor. Germination rate seedling growth were measured quantify Total amylase activity, α-amylase reducing sugar content, root activity seed weight determined. Correlations observed between the QTL analysis reveals that intervals RG393-C1087-RZ403 chromosome 3, C246-RM26-C1447 R830-R3166-RG360-C734b 5, interval Waxy 6 are four main chromosomal regions controlling Several activities, content localized in similar as The results suggest under control pleiotropic and/or closely linked QTLs. implications basis discussed.
