Genetic dissection of powdery mildew resistance in interspecific half-sib grapevine families using SNP-based maps

Genetic dissection of resistance to anthracnose and powdery mildew in Medicago truncatula.

Medicago truncatula was used to characterize resistance to anthracnose and powdery mildew caused by Colletotrichum trifolii and Erysiphe pisi, respectively. Two isolates of E. pisi (Ep-p from pea and Ep-a from alfalfa) and two races of C. trifolii (races 1 and 2) were used in this study. The A17 genotype was resistant and displayed a hypersensitive response after inoculation with either pathoge...

Regalia-Induced resistance in powdery mildew-infected grapevine plants correlates with the induction of chalcone synthase

genetic analysis of powdery mildew resistance in some barely lines

powdery mildew, caused by blumeria graminis hordei, is currently the most serious foliar disease of barley in worldwide and reduced barley yield. the use of resistant cultivars is an efficient, economical and environmentally way to control of powdery mildew in barley. in this research a half diallel design was used for genetic analysis of resistance to powdery mildew (bgh) in barley. six barley...

Optimal haplotype reconstruction in half-sib families

In the goal of genetic improvement of livestock by marker assisted selection, we aim at reconstructing the haplotypes of sires from their offspring. We reformulated this problem into a binary weighted constraint satisfaction problem. Our results showed these problems have a small treewidth and can be solved optimally, improving haplotype reconstruction compared to previous approaches especially...

selection of drought-tolerant half-sib families in sugar beet

one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...
