In recent years, in the world, scientific researches are being tcarried out to create new cultivars of the hot pepper (Capsicum annuum L.) isuitable for growing in unheated greenhouses, with a level of bitterness above n10 points, exportable, with good fruit quality, with a yield of 80-90 t/ha and also gto determine their optimal planting dates and schemes using innovative methods. Hot pepper is the main crop in the leading countries in the cultivation iof hot pepper, and it is also widely used in the industrial and pharmaceutical nfields. Therefore, creating high-yielding varieties of hot pepper suitable for cultivation in unheated greenhouse conditions is an important scientific gdirection. Selection of its varieties suitable for growing in unheated greenhouse rconditions and development of important elements of cultivation technology, as ewell as providing the population with fresh and new products throughout the eyear, is one of the urgent tasks of today. n The purpose of the study is to create hot pepper (Capsicum annuum L.) hcultivars with high yield and good fruit quality suitable for growing in ogreenhouses. u The methods of the study. The research in the greenhouse and slaboratory was conducting according to "Methodology of experimental work in evegetable and melon growing", "Methodology of conducting experiments in svegetable, melon crops and potato growing", "Guidelines for the study and .keeping the world collection of vegetable nightshade crops (tomatoes, peppers, eggplants))", "Guidelines for conducting experiments with vegetable crops in Yprotected ground structures (SRIVF)", and the statistical analysis of the results i e 171 o f DEVELOPMENT OF PEDAGOGICAL TECHNOLOGIES IN MODERN SCIENCES International scientific-online conference was carried out using the Microsoft Excel program and the dispersion analysis method of B.A. Dospekhov. The results of the study and their discussion. It is known that the planting dates has high influence on the productivity of vegetable crops, therefore it is necessary to know how to correctly choose the planting time in order to obtain high yield and good-quality harvest. During the ripening period of the fruits, in the control option of the experiment the cultivar "Sharq gavhari" produced the fruits per plant 125 pieces, when it was planted in the first option, the number of the plant fruits was 112 pieces, or 10.4% less than the control, and when planted in the second and fourth options, there was no significant difference from the control, that is, 116–128 fruits or 0.2–7.2% more than the control. The weight of fruit of hot pepper was 19 g in the control variant, 14.3– 15.4 g in the first and second variants, or 18.9–24.7% lighter than the control. Total fruit weight was 2.3 kg in the control option, it was 1.6 kg or 30.4% in plants planted in the first option compared to the control, when planted in the second variant the indicator was 1.7 kg or 26.1% lighter than the control. In the fourth option it was found to be 2.6 kg or 13% heavier than the control.
