| افزایش عملکرد در واحد سطح و همچنین معرفی ارقام جدید پنبه، یکی از مهمترین اهداف محققان میباشد. اهداف مهم دراین برنامه شناخت واریتههای برتر از نظر عملکرد میباشد. بدین منظور آزمایشی با ارقام تجاری و جدید پنبه شامل: ارقام جدید B557، T3، T2، SB35، و ارقام تجاری ارمغان، گلستان و ساحل در قالب طرح بلوک کامل تصادفی در ایستگاه تحقیقات پنبه کارکنده مورد بررسی قرار گرفتند. نتایج نشان داد که واریته T2 با 4/2159 کیلوگرم در هکتار بیشترین عملکرد را داشت. واریته SB35 با 6/1805 کیلو گرم در هکتار دارای کمترین عملکرد کل بود. گروهبندی صفت درصد زودرسی نشان داد که واریتههای B-557 با 8/75 درصد، واریته T2 با 6/74 درصد و واریته T3 با 5/73 درصد، به ترتیب زودرس ترین واریتههای مورد مطالعه در این تحقیق بودند. رقم ارمغان با 8/53 و واریته SB35 با 7/55 درصد، دیررسترین ارقام در بین واریتههای مورد مطالعه بودهاند. مقایسه میانگین وزن سی قوزه واریتههای مورد آزمایش نشان داد که از نظر این صفت، رقم گلستان با 2/172 گرم، رقم ارمغان با 1/162 گرم، رقم ساحل با 2/183 گرم، واریته SB35 با 9/172 گرم، واریته T2 با 1/177 گرم و واریته B-557 با 0/169 گرم دارای سنگینترین غوزهها بودهاند. | ||

| Yield increasing and also the introduction of new varieties of cotton is one of the main goals of researchers. The important goal of this research was recognition of superior varieties in terms of yield. New and cultivated cotton genotypes including new varieties B557, T3, T2, SB35 and commercial cultivars like Moghan, Golestan and Sahel were evaluated in a randomized complete block design in Karkandeh Cotton Research Station. The results showed that T2 variety with 2160 kg/ha had the highest yield and SB35 variety with 1806 kg/ha had the lowest yield. Variety of B-557 with 75.8 % and varieties of T2 and T3 with 73.5 and 74.6 % were the earliest genotypes, respectively. Late maturity among varieties belonged to Armaghan and SB35 varieties with 53.8 and 55.7 %, respectively. The highest and lowest bolls weight were related to Golestan cultivar with 183.2g and T3 genotype with 153/8g, respectively | ||
