The third most important food crop worldwide, potato ( Solanum tuberosum L.) is a tetraploid outcrossing species propagated from tubers. Breeders have long been challenged by polyploidy, heterozygosity, and asexual reproduction. It has assumed that tetraploidy essential for high yield, the creation of inbred not feasible, propagation seed tubers ideal. In this paper, we question those assumptions propose to convert into diploid line–based true seed. Although conversion magnitude...
Abstract As one of the world’s most important food crops, potato (Solanum tuberosum L.) has spurred innovation in autotetraploid genetics, including use SNP arrays to determine allele dosage at thousands markers. By combining genotype and pedigree information with phenotype data for economically traits, objectives this study were (1) partition genetic variance into additive vs. nonadditive components, (2) accuracy genome-wide prediction. Between 2012 2017, a training population 571 clones...
The extent of linkage disequilibrium (LD) is an important factor in designing association mapping experiments. Unlike other plant species that have been analyzed so far for the LD, cultivated potato (Solanum tuberosum L.), outcrossing species, a highly heterozygous autotetraploid. favored genotypes modern cultivars are maintained by vegetative propagation through tubers. As first step LD analysis, we surveyed both coding and noncoding regions 66 DNA fragments from 47 accessions single...
The yellow pigment in potato ( Solanum L. sp.) tuber flesh is caused by various carotenoids that may protect against cancer, cardiovascular disease, and macular eye degeneration. objectives of this research were to 1) identify quantify the present 11 diploid clones from a hybrid population phureja ssp. Juz. & Bukasov-S . stenotomum Bukasov two tetraploid cultivars (the yellow-fleshed `Yukon Gold' white-fleshed `Superior'), 2) determine relationship between intensity carotenoid content....
The development of germplasm with resistance to common scab and cold-induced sweetening is a high priority for the potato ( L.) industry. A mapping population was developed from mating two individuals diploid family generated by crossing susceptible cultivated clone US-W4 highly resistant wild relative Bitter) '524-8'. Progeny were evaluated in replicated field trials. Tubers scored percentage surface area lesions, lesion type, sweetening, average tuber weight, dry matter. Plants vine...
Early blight, caused by the fungus Alternaria solani, is one of most economically important foliar diseases potatoes worldwide. In this study, 217 tetraploid old and modern potato cultivars were evaluated for resistance to early blight in field experiments Pennsylvania 2016 2017. Relative area under disease progress curve (RAUDPC) was calculated based on visual assessment during growing season each year. RAUDPC ranged from 0.0090 0.7372 0.0215 0.7889 2017, respectively. Significant...
ABSTRACT Potato ( Solanum tuberosum L.) is one of the world's most important crops. Using a tetraploid population, we developed linkage map using amplified fragment length polymorphism and simple sequence repeat (SSR) markers, searched for quantitative trait loci (QTL) via interval mapping single‐marker analysis variance. Quantitative were detected flower color, foliage maturity, tuber skin texture, dry matter content, specific gravity, yield. Most groups anchored to chromosomes SSRs. The...
Genome-wide single nucleotide polymorphism (SNP) markers coupled with allele dosage information has emerged as a powerful tool for studying complex traits in cultivated autotetraploid potato (Solanum tuberosum L., 2n = 4× 48). To date, this approach been effectively applied to the identification of quantitative trait loci (QTLs) underlying highly heritable such disease resistance, but largely unexplored patterns inheritance. In study, an F1 tetraploid russet mapping population (162...
Abstract Early blight disease, caused by Alternaria solani Sorauer, is a serious disease of potato foliage and tubers that occurs in most potato‐growing regions world‐wide. Developing new cultivars with resistance to early may reduce losses the field storage, lessen need for fungicide applications. A total 280 clones, derived from 72 maternal half‐sib families diploid random‐mated hybrid population Solarium phureja × stenotomum were examined blight. The clones evaluated replicated trial 2...
Abstract Potato tuber blight is a disease caused by the oomycete Phytophthora infestans (Mont.) de Bary. Due to significant economic impact of this disease, introgression durable resistance into cultivated potato one top priorities breeding programmes worldwide. Though numerous loci against devastating have already been mapped, most detected are contributing towards foliar while specific information on limited. To identify genetic components and its relationship plant maturity we...
