...bited comparatively more drought tolerance with less decrease in growth rate (18.70%); total dry matter (26.94%), 100-grain weight (23.45%) and grain yield (21.50%) as compared with all other treatments. It was concluded that water stress induced at grain filling stage showed a significant impact on wheat growth as compared with other growth stage stresses. Regarding genotypes, Faisal-2008 was least affected by water stress than other varieties.

...r hybrids having greater drought tolerance are the effective and inexpensive approach by plant breeders to manage with drought. A wire house experiment was conducted in Oilseeds Research Institute, Ayub Agricultural Research Faisalabad for the screening of genotypes against drought. Ten hybrids along with their 13 parental inbred lines were grown in polythene bags following factorial structured completely randomized design by three replications against three l...

...are considered to induce drought tolerance in plants. Field trials were conducted at Agricultural Research Institute Tarnab, Peshawar-Pakistan to study the effects of moisture stress and foliar application of chemicals at different growth stages on canola growth and phenology during 2015-16 and 2016-17. The experiment comprised of four moisture levels (optimum water, 10%, 20% and 30% reduced irrigation water), three chemicals (salicylic acid 0.5mM, potassium n...

...e) role in improving the drought tolerance in okra. Drought stress (three days (control), six days (mild stress) and nine days (severe stress)) and four doses of Se (0, 1, 2, and 3 mg L−1) were imposed after 30 days of sowing. Our outcomes showed that drought stress decreases the number of leaves, plant height, number of branches, stem dry weight, root dry weight, fruit diameter, number of fruit per plant and 1000 seed weight. Visually reduction in veget...

... selection criterion for drought tolerance. Significant association was observed between chlorophyll and proline content. Osmotic adjustment was significantly correlated with relative water content and cell membrane stability. According to obtained results, genotypes NARC-09, AUR-10, SA-75, Mexipak and AUR-09 were identified as drought-tolerant, hence can serve as a good source in wheat breeding programs to develop high yielding varieties for arid, drought and...

Six generations as P1, P2, F1, F2, BC1 and BC2 were prepared for both the crosses for the estimation of gene action under generation mean analysis and planted in a triplicated Randomized Complete Block Design (RCBD) under split plot arrangement. Most of the traits in both the crosses und...

Six generations as P1, P2, F1, F2, BC1 and BC2 were prepared for both the crosses to calculate heterosis and inbreeding depression for Randomized Complete Block Design under split plot arrangement. Highly significant inbreeding depression was recorded for all traits indicating a dominant type of...

Study of drought indices revealed that the highest DTE was presented by Punjab-2008 (84.13) followed by CH12/12, D-16004, CH-09/12, TG-1218 and TG-1221 (83.84, 80.10, 72.27, 69.93 and 69.31 % respectively) coupled with lea...

Under rainfed condition the activity of all enzymes increased among all genotypes. The chick pea genotypes, GGP-1260, PGP-1426 and PB-1 were observed as drought-tolerant ones on the basis of biochemical, morphological and physiological paramete...

Three weeks old seedlings of each wheat cultivar were challenged with drought stress by skipping irrigation. After the drought stress of two weeks, plants were subjected to morphological, biochemical and physiological investigations. Drought stress reduced the...

Correlation analysis showed that the strains possessing higher number of pods plant-1, more root length and maximum grain weight were comparatively least susceptible to moisture stress along with higher yield potential. Results regarding drought indices also indicated that rela...
