چکیده مقاله :
به منظور بررسی تنوع و روابط موجود بین صفات زراعی جو، آزمایشی با 100 خانواده از نسل سوم جو حاصل تلاقی دو رقم بادیا و کومینو در قالب طرح بلوک‌های کامل تصادفی با سه تکرار در مزرعه پژوهشی دانشگاه گنبد کاووس در سال زراعی 1394-1393 اجرا شد. خانواده های جو از لحاظ طول ریشک، تعداد سنبلچه در سنبله به معنی‌داری متنوع بودند. عملکرد دانه با وزن کل سنبله، تعداد بذر جوانه زده، ارتفاع گیاه، طول ریشک و عملکرد بیولوژیک همبستگی مثبت و معنی دار داشت و بیش‌ترین میزان همبستگی بین عملکرد دانه با وزن کل سنبله مشاهده شد. در تجزیه رگرسیون گام به گام صفات تعداد بذر جوانه زده، روز تا سنبله دهی، قطر دانه، تعداد دانه در سنبله، طول ریشک سهم بالا و مؤثری در عملکرد دانه داشتند. در تجزیه علیت عاملی، صفتی که بیش‌ترین اثر مستقیم را روی عملکرد داشت تعداد بذر جوانه زده بود. با تجزیه خوشه ای به روش وارد خانواده های مورد مطالعه در سه گروه طبقه‌بندی شدند و گروه سوم به عنوان گروه مطلوب برگزیده شد. در مجموع، مهمترین عوامل مؤثر بر افزایش عملکرد خانواده های جو، تعداد بذر جوانه زده و روز تا سنبله دهی بود و با تکیه بر این صفات می توان گزینش مناسبی در جهت بهبود عملکرد دانه جو انجام داد.
To study phenotypic diversity and relationship among agronomical traits of 100 barley F3 generation families derived from cross between Badia × Komino barely cultivars, an experiment was conducted based on randomized complete block design with three replications at research field of Gonbad Kavous University during 2014-2015. Barley families had significantly high diversity in terms of awn length, spikelet no/spike. Grain yield was positive significantly correlated with total spike weight, seedlings number, plant height, awn length and biological yield and the highest correlation was observed between grain yield and total spike weight. In stepwise regression analysis, traits of seedlings number, days to heading, grain diameter, grains per spike, awn length had high contributed to grain yield. In path analysis the trait that had the most direct effect on yield was seedlings number. Barely families were classified into three groups regarding cluster analysis using Ward method and the third group was chosen as desirable one. On the whole, The most important factors influencing on yield increment of barley families was seedlings number and days to heading and these traits could be suitable choices to be used in barley breeding improvement programs.
