Selection of White Cabbage Variety Samples Those are Cultivated in Uzbekistan Conditions

There were 8 varieties and 6 F1 hybrids in total 14 white cabbage sorts were used in this study. The variety Saratoni has been used as a standard for comparison with them. According to the 4-year research data, the average weight of the cabbage head was 3, 2 kg, and compared to that cabbage heads were larger in Geant F1 for 128, 1 %, Kozak F1 121, 9 % and in W61-19 1 for 128, 1 %. The average yield of white cabbage samples has been various during 2007-2010. The yield has been 95, 7 in standard variety and in comparison to that the yields have been higher in Geant 1 (131, 2 t/ha) 137, 1 %, Kozak F1 (124, 8 t/ha) 130, 4 % and W61-19 F1 (129, 6 t/ha) or 135, 4 % higher than standard variety. Productivity indicators were significantly higher than HCP05 (1, 8-3, 9 t) and the accuracy of the experiments was higher for 1, 7-4.3 %.
