Stable quantitative trait loci (QTL) are important for deployment in marker assisted selection wheat (Triticum aestivum L.) and other crops. We reported QTL discovery using a population of 217 recombinant inbred lines multiple statistical approach including multi-environment, multi-trait epistatic interactions analysis. detected nine consistent linked to different traits on chromosomes 1A, 2A, 2B, 5A, 5B, 6A, 6B 7A. Grain yield were 2B.1 5B across three or four models GenStat, MapQTL,...
Wheat streak mosaic virus (WSMV) can cause significant yield loss in wheat ( Triticum aestivum L.) the Great Plains of North America. A recently identified WSMV resistance gene, Wsm2 , was mapped to chromosome 3BS germplasm line ‘CO960293–2’. Effective genetic markers tightly linked gene will enhance selection WSMV‐resistant lines through marker‐assisted selection. We have using a high‐density map developed from 90K Infinium iSelect single‐nucleotide polymorphism (SNP) array with recombinant...
Abstract Moderate to severe drought (water stress) at the reproductive stage is common in U.S. Southern High Plains ( SHP ), where wheat grown as a major winter crop. The objective of this study was better understand physiological basis tolerance elite cultivars. A 2‐yr glasshouse conducted using three cultivars TAM 111, 112 and 304) two water treatments (wet: adequate dry: water‐limited). Overall, 111 used more for cumulative evapotranspiration ET ) had tillers greater root mass shoot...
Irrigation for commercial and residential turf is becoming limiting, water scarcity one of the long-term challenges facing turfgrass industry. Potential root development profile characteristics provide important information regarding their drought resistance mechanisms developing drought-resistant cultivars. The objective this study was to determine potential two bermudagrass species zoysiagrass using experimental lines evaluated in were: African ( Cynodon transvaalensis Burtt-Davy), common...
ABSTRACT Mapping single nucleotide polymorphisms (SNPs) in wheat ( Triticum aestivum L.) can help to develop high throughput molecular markers for important traits. The 90K Infinium iSelect SNP array was used screen three recombinant inbred line (RIL) populations derived from crosses, CO 960293‐2/'TAM 111’ (CT), ‘TAM 112’/TAM 111 (TT), and ‘Halberd’/'Len’ (HL). objective of this study compare validate the chromosomal locations mapped SNPs wheat. A set 152, 124, 180 RILs were CT, TT, HL....
Two drought-tolerant wheat cultivars, ‘TAM 111’ and 112’, have been widely grown in the Southern Great Plains of U.S. used as parents many breeding programs worldwide. This study aimed to reveal genetic control yield components two cultivars under both dryland irrigated conditions. A mapping population containing 124 F 5:7 recombinant inbred lines (RILs) was developed from cross TAM 112/TAM 111. set 5,948 SNPs 90K iSelect array double digest restriction-site associated DNA sequencing...
Viral diseases transmitted by wheat curl mite (WCM, Aceria tosichella Keifer) have been a persistent concern to farmers and researchers for at least six decades. Yield losses caused mite–virus complexes up 100% the field level reported in several states of Great Plains. This study was conducted evaluate resistance hard winter ( Triticum aestivum L.) germplasm lines cultivars WCM. Four sets from 2014 trials were screened, including 40 Northern Regional Performance Nursery, Southern Texas...
In the U.S. Great Plains and other parts of world, Wheat streak mosaic virus (WSMV) disease is one most important biotic stresses affecting wheat ( Triticum aestivum L.) productivity. Breeding for cultivars with resistance provides a socioeconomic environmentally sustainable approach combating WSMV. The use markers as proxy quantitative qualitative traits widely applied in crop improvement programs. Among available markers, single nucleotide polymorphisms (SNPs) are routinely used plant...
