V. Ya. Yuriev of NAAS popup.description2 Object of studies - microgametophytic breeding of sunflower. Aim - to establish correlations between the traits of resistance of sunflower sporophyte and microgametophyte to the effect of unfavorable abiotic factors (especially, to temperature stress) and to propose these traits to use in microgametophytic selection of resistant genotypes. Methods - field, laboratory, selective, genetical, statistical. The procedure of evaluation of sunflower lines for heat resistance of mature pollen is elaborated (a patent for the useful model is received). In course of the studies imperfection of the existing procedure for evaluation of sporophyte resistance to temperature stress is stated. The procedure is improved the application has been submitted to receive a patent for the useful model. The necessary crosses for the study on the nature of inheritance of investigated traits have been fulfilled. A collection of the lines - sources for high heat-resisttance has been multiplied for handing over to NCPGRU Product Description popup.authors Макляк Катерина Миколаївна Сатаров Олександр Зайнулович Токар Ігор Володимирович Юшкіна Людмила Лазарівна popup.nrat_date 2020-04-02 Close
