چکیده

بمنظور مطالعه عملکرد و اجزای عملکرد و پایداری هیبریدهای جدید خارجی ذرت دانه ای (Zea mays L.)، آزمایشی با 18 هیبرید تجاری (شامل 15 هیبرید خارجی زودرس و متوسط رس) و نیز 3 رقم هیبرید تجاری ایرانی (KSC704، KSC647، DC370) به عنوان شاهد در دو سال زراعی 88-1387 و 89-1388، در قالب دو طرح بلوک کامل تصادفی با سه تکرار در مرکز تحقیقات کشاورزی و منابع طبیعی خراسان رضوی به اجرا در آمد. نتایج این آزمایش نشان داد که هیبریدهای سینگل کراس EXP1 و دابل کراس 370 با عملکرد دانه 5/16 و 1/12 تن به ترتیب برترین و ضعیف ترین هیبرید ازنظر عملکرد دانه می باشد. هیبرید EXP1 همچنین ازنظر صفات تعداد ردیف دانه در بلال، عمق دانه، طول بلال و قطر ساقه نیز برترین هیبرید بود. بررسی همبستگی ساده نشان داد که عملکرد دانه همبستگی مثبت و معنی داری با صفات ارتفاع بوته، ارتفاع بلال، تعداد ردیف دانه در بلال، عمق دانه، تعداد روز تا رسیدگی فیزیولوژیک، طول بلال و تعداد برگ گیاه دارد. همچنین مشاهده شد که صفت درصد چوب بلال بطور منفی با عملکرد همبسته می باشند. تجزیه خوشه ای با روش Ward’s و با استفاده از اطلاعات بدست آمده از هر دو سال انجام گرفت. نتایج نشان داد که ارقام ذرت دانه ای به چهار گروه مجزا تفکیک شدند.

چکیده [English]

In this study 18 corn hybrids consist of 15 new early and mid mature foreign hybrids and three commercial Iranian corn hybrids (KSC704, KSC647 and DC370) as controls were evaluated at two RCBD with three replications at the Khorasan Razavi Agricultural Research and Natural Resources Center, during 2008 -2010. Results showed that hybrid EXP1 and DC370 with 16.5 and 12.1 t.ha-1 were the best and the worst hybrids, respectively. Also, the EXP1 hybrid was better than others for no. rows, kernel depth, ear length and stem diameter. The results of simple correlation showed positive and significant correlations between grain yield with plant height, ear height, No. rows kernel depth, days to physiological maturity, ear length and leaves no. Also, we estimated negative correlation between grain yield and cob percentage. Results of cluster analysis by Wards’ method based on two years data showed that these corn varieties can be divided in four clusters.
