PHENOLOGICAL DEVELOPMENT STAGES OF COMMON WHEAT (TRITICUM AESTIVUM L.) F2 HYBRIDS UNDER LAND CONDITIONS

Abstract

This article presents the results of the analysis of the phenological development stages of F₂ hybrids of common wheat (Triticum aestivum L.) grown in arid conditions. During the research, the duration of the germination, heading and grain ripening phases of the hybrids was analyzed. Based on phenological observations, it was found that there are significant differences between the hybrid forms and the standard variety in terms of development rate, duration of the growing season and the degree of early maturity. The results obtained are of great importance in creating varieties that are adaptable to arid regions, drought-resistant and have a short growing season. Based on the results of the control experiment conducted on common wheat F2 hybrids, a hybrid that entered the early heading and early ripening phases was selected.
