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...

The objectives of this study were to investigate whether seed biopriming through drought tolerant isolates of Trichoderma harzianum induces drought tolerance in wheat. Physiological and biochemical parameters were also monitored under greenhouse conditions to explore the mechanism underlying plant water stress resilience in response to Trichoderma inoculation.The impact of bioprospecting Tricho...

Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield, harvest index, leaf area index. Intere...

The effects of two water regimes (well-watered condition or drought stress) on root length,root surface area and root volume were tested on two peanut genotypes (the drought-resistantvariety HuaYu 22 (HY22) and the drought-sensitive variety HuaYu 23 (HY23)), measured 101days after sowing. The roots were sampled from the upper (0–40 cm) and deeper (40–100 cm)soil layers. Root diameter was measur...

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 order to evaluate terminal drought tolerance in different canola cultivars based on drought tolerance indices, an experiment was conducted based on randomized complete block design (rcbd) with three replications at experimental field of seed and plant improvement institute (spii), karaj in 2008-09. results using stress tolerance index (sti), geometric mean productivity (gmp) and mean product...

Response of six sunflower hybrids/ breeding lines viz., G-101, SF-187, Hysun-33, Hysun-38, 64A-93 and S-278 to drought stress imposed at germination and seedling growth stages was investigated in a laboratory experiment (25±3C). Five water stress levels of zero (control), -0.35, -0.6, -1.33, and 1.62 MPa were developed using polyethyleneglycol-6000 (PEG-6000). Complete randomized design with th...
