Qovoqcha (Cucurbita pepo L.) nav namunalarida generativ organlarning shakllanishi va fenologik rivojlanish xususiyatlari

Abstract

This article examines the formation of generative organs and the features of phenological development in 12 varietal samples of zucchini in 2026. The study analyzed observation data based on the 10 and 75 percent thresholds of the budding, flowering, and fruiting phases. Differences were identified among the varietal samples in the onset and mass progression of generative development phases. The early or relatively late observation of flowering and fruiting processes in certain varietal samples indicates that phenological traits are variety-dependent. The obtained results can be used for the comparative evaluation of zucchini varietal samples, the selection of promising varieties, and the identification of varieties adapted to local soil and climatic conditions.
