摘要
Abstract
Quantitative trait loci (QTLs) affecting total leaf number of the main stem,leafing rate at two different growth stages,heading date,and plant height in a recombinant inbred lines (RIL)population from the cross Lemont (japonica)×Teqing (indica) were investigated using a complete RFLP map with 182 marker loci.Eight QTLs for rate of leaf growth at two different stages,two QTLs for total leaf number of main stem,three QTLs for heading date,and four QTLs for plant height were mapped.Combined with previous studies on this cross,these results provided useful information on the nature of some detected QTLs.For example,QLn3,a main-effect QTL from Teqing that give 1.5 leaf more of total leaf number,9 days delayed heading,and 0.2 leaf increase each ten days during tillering stage in greenhouse condition was identified on chromosome 3 near the marker RG348.This QTL appeared to affect the basic vegetative period of rice plants since it was not affected by the daylength.On the other hand,QHd8 which affects heading date,plant height,and total leaf number of main stem appeared to be influenced by daylength.关键词
