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...
Drought is one of the limiting factor in common bean, development of common bean varieties that adapted to drought situations is the main focus for improving food crops. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under drought stress and non-stress conditions. The field work was conducted at Melkassa Agricultural Research Center during the off-season that lai...
Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...
Abstract: This research was conducted to investigate the effect of sowing date on growth and yield of five rapeseed (Brassica napus L.) cultivars. The experimental design consisted of four randomized complete blocks (CRDB) in a split-plot arrangement. Four convetional sowing dates (11 September, 27 September, 12 October and 27 October) as main plots and five rapeseed cultivars (RGS00...
introduction the plant hormones such as salicylic acid and gibberellin can affect the quantity and quality of crops. external application of plant growth regulators as a strategy for improving salt tolerance in plants is discussed. foreign salicylic acid can regulate antioxidant enzyme activity and increase plant resistance to abiotic stresses. salicylic acid reduction due to ethylene through t...

Genetic diversity is the base of plant breeding. Hence, 33 M7 soybean mutant lines, which were evolved by γ ray from cultivar L17 irradiated with doses of 150, 200 and 250 Gray (absorbed dose), with L17 cultivar and two commercial cultivars (Clark and Williams) were evaluated in view of some morphological traits (number of leaves/plant, pods/plant, seeds/pod, seeds/plant, 100-seed weight, dry w...
Drought stress is one of the most important environmental stresses affecting plant growth, yield and crop production around the world. It is believed that arbuscular mycorrhizal fungi are used for protecting plants against drought damage.Vesicular-arbuscular mycorrhizal fungi have been used in recent years to cope with water stress in many plants. In this study, the relationship between water d...
introduction safflower is native to iran, and is cultivated for high adaptability, low water requirement, resistance to drought and useful unsaturated fatty acid (ashri et al., 1977). identification of effective agronomic traits and relationship between them are important aims under water stress conditions. among these characters, grain yield is the most important trait that is genetically poly...
