Cassava is an important root crop to resource-poor farmers in marginal areas, where its production faces drought stress constraints. Given the difficulties associated with cassava breeding, a molecular understanding of drought tolerance in cassava will help in the identification of markers for use in marker-assisted selection and genes for transgenic improvement of drought tolerance. This study...
In order to evaluate drought tolerance indices in chickpea, determination of the best indicator of drought tolerance and identifying tolerant cultivars in water limited condition, a randomized complete block design (RCBD) with three replications and 20 chickpea genotypes was used under irrigation and rainfed conditions at research farm of College of Agriculture, Razi University, Kermanshah. Th...
This study was performed to investigate the effects of drought stress on agronomic traits, post-drought recovery, and survival of tall fescue genotypes in the Research Farm of the Isfahan University of Technology located in Lavark, Najafabad, central Iran. In this study, 67 tall fescue genotypes, including three groups of the early, medium, and late in terms of flowering were studied. All genot...
Drought is one of the major abiotic stresses affecting wheat yield. A recurrent selection program was conducted to improve the drought tolerance and yield of bread wheat using drought tolerant advanced breeding lines from a drought tolerant x susceptible cross (HI 1500 x HUW 510). The parental lines were evaluated for yield, biomass and harvest index (HI) in addition to the drought adaptive tra...
to evaluate genetic variation and to study of dry matter remobilization towards seed, 64 bread wheat genotypes were examined in two separated experiments using alpha-latic design of 2 replications during 2002–2003. significant differences observed for most traits in normal and drought conditions. there were considerable variations among genotypes for independent parameters of dry matter remobil...
Physiological basis of genetic variability in drought response and its association with yieldand related indices is not clear in Brassica. In this study 36 accessions belonged to sevenspecies of Brassica were evaluated under normal, moderate and severe stress environments.Physiological traits along with seed yield, seed yield components, oil content and two selectionindices (stress tolerance in...
Selection for drought tolerance typically involves evaluating genotypes for either high yield potential or stable performance under drought stress. In order to select drought tolerant land races of bread wheat an experiment was conducted in a randomized complete block design (RCBD) with three replications under two different rainfed and irrigated conditions during the growing season 2010-2011. ...
In order to study of agronomic, physiological characteristics, drought tolerance and to identify Agro-physiological traits associated with drought tolerance, 19 durum wheat genotypes consisting of 17 advanced breeding lines and two control cultivars (Saji and Zahab) were evaluated in a randomized complete blocks design with three replicated under both stress (rainfed condition) and non-stress ...
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...
