a camel research station was established in 1990 at the central desert land of iran named kavir-e-loot, to evaluate productivity performance of one humped camel. the data consisted of birth weights (bw), three (w3), six (w6), nine (w9) months and yearling (w12) body weight of animals and the pedigree was registered during a period of 14 years since 1991 to 2004. the body weight traits of birth,...

almost half of agricultural lands in iran are saline and it is one of the most important constraints in cultivated lands. wheat is the most important crop in saline lands in rotation of golestan province. since saline soils amelioration is so expensive, achievement of genotypes with tolerant and high yield potential is essential. 22 genotypes of selective wheat of recent experiments with three ...

abstract a field experiment was conducted to study the competitiveness of wheat cultivars against bromus japonicus at sistan agricultural research station during 2003. the experimental design was a randomized complete block assigned in factorial arrangement of treatments with four replications. six wheat cultivars comprised two natives (old cultivars; boulani and kalak-afghni), and four new-rel...

twenty-two bread wheat cultivars along with susceptible (sholeh) and resistant (azadi) control cultivars were evaluated for resistance to russian wheat aphid of two growth stages including seedling and stem elongation in greenhouse. five adult aphids per plant were used for infestation. leaf chlorosis at seedling and stem elongation stages and leaf rolling at seedling stage were measured. other...

in order to study the realationship between genetic diversity and different characteristics associated with grain yield in barley, 28 genotypes of barley cultivars contain seven cultivars and 21 hybrids were evaluated in randomized complete block (rcb) design with three replications. cultivars were valfajr, makuei, kavir, rayhan, gorgan, nusrat and nimroz. this study was carried out in research...

in order to compare morphophysiological traits between new and old cultivars of barley (hordeum vulgare l.) a greenhouse experiment was conducted in greenhouse condition in faculty of agriculture, ferdowsi university of mashhad in spring and summer 2011.the type of experiment was a completely randomized design with eight treatments (nosrat , youssof , fagr30 , nick) and four old cultivars inclu...

frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...
