Significant positive correlationswere found between grain yield, panicle traits and the No.of peduncle vascular bundles. So, it is very important tostudy the inheritance of peduncle vascular bundle, whichis a quantitative trait.展开更多

The inhibited effect ofwater-soluble extract of 123 DH pure lines leaves on the let-tuce roots growth was investigated, and the QTLs analysis of rice allelopathy was carried out. Totally, four QTLs related to rice allelopathy were detected, and they were on chromo-somes 3, 9, 10 and 12, respectively. The LOD scores were3.40, 2.68. 2.75 and 3.08, respectively. Among them, additive effects of the QTLs on chromosomes 3 and 10 were 1.65 and 1.43, on chromosomes 9 and 12 were -1.44 and -1.58, re-spectively. Allelopathy characteristics of another three com-mon rice varieties were also studied.展开更多
