Results of varietal testing of peking cabbage with a repeated planting in Uzbekistan

Peking cabbage is widespread in the countries of South-East Asia. For Uzbekistan, it is a little-known culture. In connection with this, the variety testing of 8 hybrids and 2 varieties of this foreign selection culture was carried out. By results of researches it was revealed that hybrid Seo Jin F1and Monoko F1 are the most productive and early ripening. The difference in the yield of these two hybrids with other tested varieties and hybrids in most years of study was quite reliable and exceeded the NDS. However, the seeming on the initial scale of large additional costs when using the identified high-yielding hybrids are more than pay off due to a high surplus yield. The highest yield was generated by hybrids Seo Jin F1, Monoko F1 and Jang Won F1, which formed the largest heads. By weight and number of heads, the commodity and non-commodity yields and the average weight of the head were determined. Field experiments were laid on the experimental and investigational base of the research institute of plant growing located in the Qibray district of the Tashkent region.
