Phytophthora blight (PB) caused by nicotianae is a highly destructive disease in sesame ( Sesamum indicum L.). In this study, we used linkage mapping and genome-wide association study (GWAS) to identify quantitative trait loci (QTL) candidate genes associated with PB resistance. The QTL 90 RILs of the Goenbaek × Osan cross using genotyping-by-sequencing detected significant QTLs for resistance ...

Mungbean (Vigna radiata (L.) R. Wilczek var. radiata) yield is dramatically constrained by powdery mildew (PM) caused Sphaerotheca phaseoli (Z.Y. Zhao) U. Braun (1985), which considerably prevalent in the cool-dry season of production South, East, and Southeast Asia countries including Thailand. Exploitation varieties resistant to disease crucial meet sustainable production. A population 64 F2:...

Tef (Eragrostis tef [Zucc.] Trotter) is a tiny-seeded cereal with huge importance in Ethiopia. Creation of variability by hybridization and the subsequent selection RILs very important towards variety development. In order to identify superior genotypes, evaluation was performed on eight environments using three times replicated randomized complete block design. The result revealed that genotyp...

Quantitative trait loci (QTLs) associated with eating quality, grain appearance quality and yield-related traits were mapped in recombinant inbred lines (RILs) derived from closely related rice (Oryza sativa L. subsp. japonica) cultivars, Yukihikari (good eating quality) and Joiku462 (superior eating quality and high grain appearance quality). Apparent amylose content (AAC), protein content (PC...

Most agricultural traits are controlled by quantitative trait loci (QTLs); however, there are few studies on QTL mapping of horticultural traits in pepper (Capsicum spp.) due to the lack of high-density molecular maps and the sequence information. In this study, an ultra-high-density map and 120 recombinant inbred lines (RILs) derived from a cross between C. annuum'Perennial' and C. annuum'Demp...

In this study, one rice population of recombinant inbred lines (RILs) was used to determine the genetic characteristics of seed reserve utilization during the early (day 6), middle (day 10) and late (day 14) germination stages. The seedling dry weight (SDW) and weight of the mobilized seed reserve (WMSR) were increased, while the seed reserve utilization efficiency (SRUE) decreased, during the ...

Quantitative approaches conducted in a single mapping population are limited by the extent of genetic variation distinguishing the parental genotypes. To overcome this limitation and allow a more complete dissection of the genetic architecture of complex traits, we built an integrated set of 15 new large Arabidopsis thaliana recombinant inbred line (RIL) populations optimized for quantitative t...

Environmental factors during juvenile growth such as temperature and nutrition have major effects on adult morphology and life-history traits. In Drosophila melanogaster, ovary size, measured as ovariole number, and body size, measured as thorax length, are developmentally plastic traits with respect to larval nutrition. Herein we investigated the genetic basis for plasticity of ovariole number...

A set of 585 informative single-nucleotide polymorphism (SNP) loci was used to genotype both a panel of diverse accessions and a set of recombinant inbred lines (RILs) bred from the cross Zhongpin03-5373 (ZP; resistant to SCN) × Zhonghuang13 (ZH; susceptible). The SNP loci are mostly sited within genic sequence in regions of the soybean [ (L.) Merr.] genome thought to harbor genes determining r...
