چکیده

به­ منظور تعیین ارزش زراعی و مصرف (VCU) شش رقم و ژنوتیپ جدید پنبه حکمت، ارم3، شایان، شایان کلاستر، اس492 وn-sk (b-23)  در مقایسه با ارقام شاهد متداول کاشت بختگان و گلستان در استان فارس (داراب) در سال­ های1393 و 1394 عملکرد وش، وزن غوزه، تعداد غوزه هر بوته، زودرسی، وزن صد دانه، کیل، طول، ظرافت، استحکام، یکنواختی و کشش الیاف ارزیابی شدند. نتایج نشان داد رقم حکمت از بیشترین عملکرد وش (4177 کیلوگرم در هکتار)، تعداد غوزه در هربوته (19/5)، شاخص زودرسی (94 درصد)، کیل (35/8) و شاخص ظرافت الیاف (4/2 میکرونر) برخوردار بود. رقم بختگان دارای بالاترین وزن صد دانه (11/26 گرم)، وزن غوزه (5/5 گرم) در سال1394، طول (28/85 میلی­ متر)، یکنواختی (86/8 درصد) و کشش (6/5 درصد) الیاف بود. همچنین بیشترین استحکام الیاف (31/8 گرم بر تکس) به ژنوتیپ n-sk (b-23) تعلق داشت. بنابراین رقم حکمت و ژنوتیپ ارم3 به ­لحاظ عملکرد وش و زودرسی از برتری نسبت به سایر ارقام و ژنوتیپ­های جدید و ارقام شاهد بررسی شده برخوردار بودند. بنابراین به­ طور بالقوه دارای قابلیت تجاری­سازی و معرفی به­ عنوان ارقام تجاری در استان فارس بودند.

چکیده [English]

In order to compare value of cultivation and use (VCU) of six new cotton cultivars and genotypes, Hekmat, Eram3, Shayan, Cluster Shayan, S492 and n-sk (b-23) with Bakhtegan and Golestan common cultivated cultivars in Fars province (Darab research station) during 2014 and 2015 years, seed cotton yield, boll weight, boll number per plant, earliness, 100 kernel weight, gin turn out, fibers length, fitness, strength, uniformity and elasticity s were evaluated. Results revealed that Hekmat cultivar had the most seed cotton yield (4177 kgha-1), boll number per plant (19.5), earliness (94 %), lint percent (35.8%) and fibers fitness (4.2 Micronair). Bakhtegan cultivar had the most100 kernel weight (11.2625 gr) and boll weight (5.5 gr) in 2015, fiber length (28.85 mm), uniformity (86.8 %) and elasticity (6.5 %). Also the most fiber strength (31.8 grtex-1) belonged to n-sk (b-23) genotype. Therefore, Hekmat cultivar and Eram3 genotype for seed cotton yield and earliness were superior to studied new cultivars and genotypes and control cultivars and had potential ability for commercialization and introduction as new commercial cultivars in Fars province.
