Evaluation of adaptation and grain yield stability of durum wheat (Triticum turgidum L.) genotypes in temperate agro-climate zone of Iran
Identification of adapted genotypes with high grain yield is the most important goal in durum wheat breeding programs. To study adaptation and grain yield stability of durum wheat genotypes, 18 durum wheat promising lines with two commercial durum and bread wheat cultivars were used. The durum wheat genotypes were evaluated in four locations; Isfahan, Karaj, Kermanshah and Neishabour in tempera...
متن کاملThe Impact of Climate Change on Grain Yield and Yield Variability in Iran
In this paper, we have examined the effect of climate variables on the yield average and variability of major grain crops (rice, maize, and wheat) in Iran from 1983 to 2014. For this purpose, we made use of the Just and Pope Production Function crop yields panel data. The results revealed that the influences of climate variables were different in the crops. The time trend positively influenced ...
متن کاملComplex agro-ecosystems for food security in a changing climate
Attempts to increase food crop yields by intensifying agricultural systems using high inputs of nonrenewable resources and chemicals frequently lead to de-gradation of natural resources, whereas most technological innovations are not accessible for smallholders that represent the majority of farmers world wide. Alternatively, cocultures consisting of assemblages of plant and animal species can ...
متن کامل“Agro-meteorological indices and climate model uncertainty over the UK”
Five stakeholder-relevant indices of agro-meteorological change were analysed for the UK, over past (1961–1990) and future (2061–2090) periods. Accumulated Frosts, Dry Days, Growing Season Length, Plant Heat Stress and Start of Field Operations were calculated from the E-Obs (European Observational) and HadRM3 (Hadley Regional Climate Model) PPE (perturbed physics ensemble) data sets. Indices w...
متن کاملEvaluation of Grain Yield, Agronomical Traits and Drought Tolerance Indices in Some Bread Wheat Cultivars
In order to study genetic variation and effect of drought stress on grain yield, some agronomical traits and 13 drought tolerance indices, an experiment was conducted on nine cultivars at Shahid Bahonar University of Kerman research field. The experimental layout was conducted in a randomized complete block design with three replications under two complementary irrigation and dryland condi...
