The main objective of this research was to evaluate fifteen durum wheat (Triticum durum) genotypes selected from joint project of Iran/ICARDA for drought tolerance using several indices. The trials were conducted under moderate levels of drought stress for three cropping seasons (2004-2006) in four locations in the highlands western of Iran. The combined ANOVA for grain yield over years and loc...

in order to evaluate the utilization ability of drought resistance indices such as: yield index (yi), yield stability index (ysi), stress susceptibility index (ssi), tolerance (tol), mean productivity (mp), geometric mean productivity (gmp) and stress tolerance index (sti) in sunflower hybrids, three separate experiments were conducted as randomized complete block design at the research field o...

Breeding for environmental stress is one of the most important goals in plant breeding. Among stresses, drought stress has high influencing on limitation of maize production. Therefore, in order to find the best drought tolerant hybrids, 38 maize hybrids were planted in two separate experiments: one with optimum irrigation (control) and another with water stress at grain-filling stage in Moghan...

Drought is one of the major problems affecting crops production, including corn, in many parts of Iran. In order to detect drought tolerant grain corn hybrids, an experiment with twenty corn hybrids was conducted during 2006 in Qom Province, Iran, using a complete randomized block design with four replications, under optimal moisture and drought stress condition. Results showed diversity among ...

     Drought is one of the major environmental limiting factors in the global agriculture. Exploiting of crop yield potential and increasing yield stability of them in drought and drought-prone regions can be guaranteed to feed the world’s growing population. For this purpose, in order to assess the late season drought tolerance genotypes and determining of tolerant them using stress tolerance ...

the first step in identification of genes which control traits in stress and no stress conditions is localization of chromosomal related to traits. in order to locate the genes controlling drought resistance and screening quantitative indices of drought resistance in wheat, substitution line series of hope into the genetic background of chinese spring (cs) were tested in a randomized complete b...

in eastern austria, alfalfa is usually grown as a rainfed crop in crop rotations in organic farming systems, where yearto- year rainfall fluctuations cause different levels of drought stress. to identify the suitability of different alfalfa genotypes and drought tolerance indices, 18 contrasting alfalfa genotypes were evaluated under irrigated and rainfed conditions at the research station of t...

Drought stress is an important limiting factor for plant growth.  Using selection indices, it is possible to identify cultivars with high yield in normal and stressed conditions.  So, the genetic analysis of drought tolerance indices can play important role in plant breeding programs. In order to identify molecular markers linked with drought tolerance indices in sunflower, 72 recombinant inbre...

drought stress, especially drought at terminal stages, plays an important role in reduction of yield in field crops such as common beans. 50 genotypes of common bean including 3 control genotypes (dehghan, bahman and naz) were used to evaluate and identify the tolerant genotypes. this experiment were performed in a randomized complete block design (rcbd) with three replications under two condit...
