چکیده مقاله :

برخی صفات فنولوژیک، مرفولوژیک، عملکرد و اجزای عملکرد دانه ژنوتیپهای نخود با کشت پاییزه تحت شرایط دیم، طی آزمایشی در ایستگاه تحقیقات کشاورزی و منابع طبیعی اردبیل در سال زراعی 90-1389 مورد مطالعه قرار گرفت. 15 ژنوتیپ مقاوم به سرما در قالب طرح بلوکهای کامل تصادفی در چهار تکرار مطالعه گردید. صفات تعداد روز تا گلدهی، غلافبندی و رسیدگی، ارتفاع بوته، تعداد شاخه، تعداد غلاف پر و خالی، تعداد دانه در بوته، وزن صد دانه، عملکرد بیولوژیک، شاخص برداشت و همچنین عملکرد دانه تک بوته مورد مطالعه قرار گرفتند. نتایج تجزیه واریانس نشان داد که صفات مورد مطالعه به استثناء تعداد غلاف خالی در بوته، به طور معنیداری تحت تاثیر تیمارهای آزمایش قرار گرفتند. ژنوتیپهای (Flip98-138C*Sel99TER85074)*SEL99TH15039 و CA9783007*Sel99TER85534 به تریبت بیشترین و کمترین تعداد روز تا گلدهی را داشتند. بالاترین ارتفاع بوته متعلق به ژنوتیپ Flip 97-118 C بود و کمترین مقدار آن متعلق به ژنوتیپ Local varirty بود. همین ژنوتیپ بیشترین تعداد شاخه را داشت. ژنوتیپ CA9783007*Sel99TER85534 بیشترین تعداد غلاف پر و دانه در بوته را دارا بود، درحالیکه کمترین تعداد دانه در بوته متعلق به ژنوتیپ Djam بود. بالاترین وزن صد دانه از ژنوتیپهای (ILC4291*Flip98-129 C)*S 98008 و S99326*SEL99TH15042 به دست آمد. بالاترین عملکرد دانه تک بوته از ژنوتیپ CA9783007*Sel99TER85534 به دست آمد، همین ژنوتیپ بالاترین زیست توده تک بوته و شاخص برداشت را نیز داشت. همبستگی مثبت و معنیدار بین تعداد غلاف پر و دانه در بوته، وزن صد دانه، عملکرد زیست توده و شاخص برداشت با عملکرد دانه مشاهده شد.

چکیده انگلیسی:

A study of some phonological, morphological traits with yield and yield components of chickpea genotypes in Fall planting under dry farming condition was carried out through an experiment at Agricultural and Natural Research station of Ardabil in 2010-2011. The experiment was carried out in a randomized complete block design with 15 chickpea genotypes with four replications. Characteristics were days of anthesis, poding , maturity, plant height, number of branches, number of fertile and non-fertile pod, number of seed per plant, 100-seed weight, biomass yield , harvest index and seed yield per plant. The results of variance analysis showed that all of studying traits except non-fertile pod per plant were significantly affected by experiment treatments. ( Flip 98-138C*Se 199 TER 85074)*SEL99TH15039 and CA9738007*SEL99TER85534 genotypes had maximum and minimum days to anthesis, respectively. The highest plant height belonged to Flip97-118C genotype and Local variety had the lowest value. This genotype had the highest branches per plant. CA9783007*SeL99TER 85534 genotype had the highest fertile pod and seed per plant, although the lowest seed number per plant belonged to Djam genotype. The highest 100-seed weight was obtained from ( ILC4291*Flip98-129C)*S98008 and S99326*SEL99TH15042 genotypes. This genotype had the highest biomass per plant and harvest index, too. There were positive and significant correlations between number of fertile pod and seed per plant, 100-seed weight, biomass and HI with seed yield.
