Quantitative trait loci for flowering time and morphological traits in multiple populations of Brassica rapa.
Wide variation for morphological traits exists in Brassica rapa and the genetic basis of this morphological variation is largely unknown. Here is a report on quantitative trait loci (QTL) analysis of flowering time, seed and pod traits, growth-related traits, leaf morphology, and turnip formation in B. rapa using multiple populations. The populations resulted from crosses between the following ...
متن کاملQuantitative Trait Loci in Brassica rapa
This paper briefly examines current methodology for developing genetic linkage maps and using them to find loci for quantitative traits (QTL). Maximum likelihood interval mapping is viewed as an extension of classical least squares methods when the trait of interest is normally distributed and located near a genetic marker. Some problems in finding multiple loci for a quantitative trait are exa...
متن کاملQuantitative trait loci for glucosinolate accumulation in Brassica rapa leaves.
Glucosinolates and their breakdown products have been recognized for their effects on plant defense, human health, flavor and taste of cruciferous vegetables. Despite this importance, little is known about the regulation of the biosynthesis and degradation in Brassica rapa. Here, the identification of quantitative trait loci (QTL) for glucosinolate accumulation in B. rapa leaves in two novel se...
متن کاملMapping of quantitative trait loci for the bolting trait in Brassica rapa under vernalizing conditions.
Premature bolting can occur occasionally during spring cultivation of heading Chinese cabbage in East Asia when the plants encounter low temperatures (vernalization), leading to economic loss. Breeding bolting-resistant cultivars is the best choice for solving this problem. We looked for QTLs responsible for varietal differences in the bolting trait in Brassica rapa under environmental conditio...
متن کاملQuantitative trait loci mapping of panicle traits in rice
In this study 90 individuals of recombinant inbred lines (RILs) were developed by crossing subspecies of japonica rice cultivar, ‘Nagdong’ and an indica type cultivar, ‘Cheongcheong’. These individuals were used to identify the quantitative trait loci of panicle traits using SSR markers. A genetic linkage map was constructed using one hundred fifty four simple sequence repeat ...
