Studiul unor trăsături asociate cu productivitatea la hibrizi experimentali de floarea-soarelui. In: Conferința “Genetica, fiziologia şi ameliorarea plantelor”. Ediția 7, 4-5 octombrie 2021, Chişinău. Chişinău: Tipogr. "PrintCaro", 2021, pp. 198-201.

The analyses of Pearson correlation coefficients showed significant, but low, positive correlations between yield and number of full seeds per calatidium, weight of total seeds per calatidium, weight of 1000 seeds and hectolitre weight. There were also observed positive correla- tions between plant height and number of leaves.rosunflowerhybridsproductivity indicesArticle
