Maqolada, g‘о‘zaning О‘zbekiston navlari va tizmalari hamda nav namunalarida tola chiqimi va uzunligining shakllanishi keltirib о‘tilgan. Tadqiqotlarda tola chiqimini oshirishda о‘rganilgan Xitoy nav namunalarining barchasi donorlar hisoblanadi, shu bilan qatorda T-3077 va T-3079 tizmalarining afzalligi qayd etilgan. Mikroneyr bо‘yicha о‘rganilgan navlar, tizmalarning, Xitoy nav namunalarining barchasi, tolaning solishtirma uzilish kuchi bо‘yicha Sirdaryo-1 va Sayxun navlarining ustunligi, Xitoy nav namunalari orasidan XT-653 va XLZ-52 nav namunalarining ustunligi, tolaning uzunligi bо‘yicha Sirdaryo-1, S-5707, S-5712 navlari va T-3079 tizmasi, XT-651 va Zenhen-1402 nav namunalarining ustunligi, bir xillilik indeksi bо‘yicha barcha navlar, tizmalar va nav namunalarning talab darajasida shakllanganligini yoritilgan.
