چکیده
Abstract Conservation agriculture (CA) practices are becoming more important in Mediterranean rainfed areas due to their potential minimize climatic risk, reduce soil erosion, and improve quality water availability. Due minimum disturbance crop residue retention, the environment for growth development can differ between CA conventional tillage (CT) practice. However, breeding targets improving yield performance system remain poorly explored. The objective of this study was assess elite genotypes barley, chickpea, lentil, wheat grown under CA, a promising alternative agricultural practice conditions. A three-year field study, with contrasting rainfall pattern, conducted International Center Agriculture Research Dry Areas’s research Morocco evaluate × genotype interaction its consequence wheat. Thirteen each were planted both CT systems. Wheat chickpea produced significantly higher grain (+62% +43% chickpea) than CT, while lentil barley performed equally Significant effect frequent lentil. Increased mainly dry year, associated harvest index (HI). For species influenced by amount distribution (75–88% variation), little importance. overall results suggest that specific program wheat, may not be efficient. Few interaction, especially years, indicated target on increasing HI, tolerance drought (high years), wet year) help system. Varieties wider adaptability considering tolerance, stability, adoption context environment. Integrating trade-off analysis stability gradient national certification scheme varieties efficient developing programs type

Evaluation of grain yield and repeatability of drought tolerance indices for screening chickpea (Cicer aritinum L.) genotypes under rainfed conditions
In order to identify drought tolerant chickpea genotypes, an experiment was conducted in the west of Iran, during 2007-2009 cropping seasons. Several selection indices were used to illustrate genotypic differences in response to drought stress. The results of combined analysis of variance showed that year, genotype, stress conditions and their interaction effects were highly significant. Correl...

Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...
