During the research, the prospects of a number of local and introduced seedless grape 12 varieties were evaluated on the basis of a "new model", which includes 25 ampelographic indicators 13 of OIV, and morphometric sizes of berries and bunches, including yield indicators, were studied. It 14 was revealed that the grape varieties differ significantly in their ampelodescriptor indicators. The 15 overall assessment of prospects, calculated from the score which was obtained for each descriptor 16 indicator, significantly differed by grade and changed in a wide range from 101.8 (Khyrcha 17 kishmish) to 162.5 (Sultany kishmish) points. It was determined that 1 variety is unpromising, 3 18 varieties are quite promising, 14 varieties are extremely promising in comparison with the control. 19 Researches have shown that the studied grape varieties also differ significantly in the yield 20 of the vine. So, this indicator ranged from 5.3 (Khyrcha kishmish) to 12.8 kg (Attica). Mathematical 21 and statistical analysis of the significance level of the average yield of the studied varieties 22 compared to the control (by U-factor) and the average growth compared to the control (∆ ,%) 23 showed that only three of the local varieties (Ag oval kishmish, Ag kishmish, Gara kishmish), and 24 six of the introduced varieties (Attica, Superior, Autumn Royal, Danuta, Centennial seedless, 25 Sultanina) have significant reliability compared to the control variety Asgeri. Compared with the 26 control, the average growth of the varieties of Kishmish Sogdiana, Kishmish Zarafshan, Sary 27 kishmish, Khyrcha kishmish, Gyrmyzy kishmish was zero or negative (0 and -29.4%), while other 28 varieties (Ag oval kishmish, Gara kishmish, Chahrayi kishmish, Attica, Superior, Danuta, etc.) had 29 a significant positive growth (5.6-88.2%).
