Morpho-biological peculiarities of growth and development of the main culture of current (ribes vilgare l.) in Uzbekistan

This scientific article presents the results of a study on the growth and development of collection varieties of currants in order to identify the most promising for cultivation in Uzbekistan. Research has shown that the control variety Uzbekistan large-fruited and Elixir differ in hardness in the development of shoots in the above-ground part. 96,5-97.5 cm. Of the tested varieties of currant, the earliest onset of the flowering phase was observed in the Herod variety - March 23; in the others, somewhat later. The late start of flowering was possessed by the Siyuma variety, in which this phase began on March 27, that is, four days later. The mass flowering phase (75%), as well as its onset, occurred most early and more intensively in the Herod variety, 10 days later in the Uzbek sweet variety. The control variant, the Uzbekistan large-fruited variety, ended this phase five days later than the Uzbek sweet variety. Of the studied collection varieties of currants, the phase of the full set of berries most intensively for 30 days, as expected, was observed in the Herod variety. In the Elixir variety, the complete set of berries ended two days later, in the rest within 34-36 days.
