VARIABILITY AND HERITAGE OF MORPHOPHYSOLOGICAL SYMPTOMS IN BIOLOGICAL PLANTS IN THE PROCESS OF SELECTION OF SUNBULL PLANTS
Abstract
The total water content, dominance and flexibility coefficients in the leaves of F1- F2- F3 plants of hybrid combinations obtained from simple and complex hybridization to create a water-resistant selection material of sunflower from oilseeds were studied. This study showed that this trait is inherited differently in simple and complex F1, F2 and F3 hybrids under different water regime conditions, with F2 hybrid combinations varying depending on the dominance coefficients and water supply conditions in hp as well as the composition of the parent forms of hybrids. The plants showed that the total amount of water in the leaves depends not only on the conditions of water supply but also on the genotypic composition KEYWORDS: Sunflower, morphophysiological, heredity, hybrid, drought tolerance, yield, seed core, ripening, cohesion, variability, hybridological analysis.
