Abstract

Aim. Characterization of recombinant inbred lines F7 Luzanivka odeska/Odeska chervonokolosa by polyphenol oxidase (PPO) genes using KASP technologies and detection of the associations of allelic differences in Ppo genes with agronomically important traits of common wheat. Methods. Competitive allele-specific PCR (KASP). Phenological observations, elements of yield structure. Results. The polymorphism of the parental genotypes and the population of recombinant inbred lines for Ppo-A1 and Ppo-D1 genes was evaluated. A polymorphism between parental forms on the Ppo-D1 gene was detected. A comparison of the data of KASP-analysis of lines with the results of evaluation of lines by eight agronomic traits of wheat was carried out. Conclusions. Differences in the alleles of the Ppo-D1 gene did not affect the traits duration of a period prior to heading, plant height, productive tillering, grain number per spike, thousand-grain weight, productive tiller number per unit area and grain yield. An increase in the grain weight per spike was observed in lines with a favorable Ppo-D1a allele. The selection of genotypes with the Ppo-D1a allele, which corresponds to the low activity of the PPO enzyme, does not have a negative effect on the agronomically important characteristics of wheat.
