AMMI Model to Estimate GxE for Grain Yield of Dual Purpose Barley Genotypes

Effects of Foliage Removal and Using Different Nitrogen Rates on Remobilization of Pre-anthesis Assimilates to the Grain in a Dual-purpose (Forage and Grain) Barley

In order to study the source limitation and contribution of pre-anthesis assimilates to grain in dual-purpose (forage and grain) barley, a field experiment was carried out in Iran, Ahvaz region. The experimental design was split plot in randomized complete block with three replications. Application rates of nitrogen at four levels (60, 120, 180 and 220 kg.ha-1 N) were as main plots, while sub p...

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Evaluation of yield of promising dual purpose grain- forage sorghum lines (Sorghum bicolor L. Moench) using drought tolerance indices

To evaluate and select the promising lines of dual purpose grain-forage sorghum under drought stress conditions, a field experiment assplit plot arrangements in randomized complete block design with three replications was carried out atresearch field station of Seed and Plant Improvement Research Institute, Karaj, Iran, in 2014 and 2015 growing seasons. Irrigation levels (60 mm, 120 mm and 180 ...

Breeding Value of Primary Synthetic Wheat Genotypes for Grain Yield

To introduce new genetic diversity into the bread wheat gene pool from its progenitor, Aegilops tauschii (Coss.) Schmalh, 33 primary synthetic hexaploid wheat genotypes (SYN) were crossed to 20 spring bread wheat (BW) cultivars at the International Wheat and Maize Improvement Center. Modified single seed descent was used to develop 97 populations with 50 individuals per population using first b...
