For winter bread wheat the genotypes were identified on Vrd-gene system in 54 stocks and on Ppd-gene system in 76 stocks, for spring durum wheat they did on Vrn-gene system in 38 cultivars. The effects of Vrn and Vrd genes were evaluated on various agronomic traits. The periods of Ppd genes action were determined during ontogenesis of wheat Product Description popup.authors popup.nrat_date 2020-04-02 Close
