Genetic relationships between plant height and root morphology were investigated in a diverse set of wheat germplasm [199 double-haploid progeny derived from a cross between Avalon and Cadenza (Triticum aestivum L.), Rht near-isogenic lines (NILs), and accessions from the Watkins Collection] to investigate whether Rht genes controlling shoot height also control seedling root growth. A germinati...

Low temperature is a major limiting factor in rice growth and development. Mapping of quantitative trait loci (QTLs) controlling cold tolerance is important for rice breeding. Recent studies have suggested that bulked segregant analysis (BSA) combined with next-generation sequencing (NGS) can be an efficient and cost-effective way for QTL mapping. In this study, we employed NGS-assisted BSA to ...

BACKGROUND The objective of this study was to dissect into quantitative trait loci (QTLs) the large morphological and physiological differences between cultivated azuki bean (Vigna angularis) and a wild relative and to infer the commonalities of the QTLs for domestication-related traits across the Asian Vigna and with other warm-season legumes. METHODS Two linkage maps, for the BC(1)F(1) and ...

basal stem rot caused by sclerotinia sclerotiorum (lib.) de bary is one of the most important diseases of sunflower. quantitative trait loci (qtl) implicated in partial resistance to two isolates of s. sclerotiorum (ssu107 and sskh41) were investigated using f9 recombinant inbred lines (rils) from the cross between sunflower parental lines pac2 and rha266. experiments were conducted in complete...

The cross between Arabidopsis thaliana and the closely related species Arabidopsis arenosa results in postzygotic hybrid incompatibility, manifested as seed death. Ecotypes of A. thaliana were tested for their ability to produce live seed when crossed to A. arenosa. The identified genetic variation was used to map quantitative trait loci (QTLs) encoded by the A. thaliana genome that affect the ...

A linkage map of pea was constructed based on a 104 RIL population derived from the cross combination Wt10245 x Wt11238. The map, which consisted of 204 morphological, isozyme, AFLP, ISSR, STS, CAPS and RAPD markers, was used for interval mapping of the QTLs controlling the stem length and internode number of pea. In the characterization of a given QTL, we included an identification of its posi...

A meta-QTL analysis was conducted in Indian mustard to identify robust and stable meta-QTLs (MQTLs) by utilizing 1504 available QTLs, which included 891 QTLs for yield-related traits 613 quality traits. For traits, a total of 57 MQTLs (YRTs_MQTLs) were uncovered from the clustering 560 projected had 4.18-fold smaller confidence interval (CI) than that initial whereas, as many 51 (Quality_MQTLs)...

Upland rice plays a major role in the sustainable food security of the country. Early vigour trait is important in the drill-sown rice for weed suppression as well as initial establishment. The IR64/Azucena was used as a reference population to identify Quantitative Trait Loci (QTLs) for early vigour related traits. The Simple Sequence Repeat (SSR) markers flanking QTLs in IR64/Azucena and othe...
