ABSTRACT Scarcity of good quality water is a limiting factor for irrigated agriculture, especially in semi-arid regions, which induces the use waters with high salt concentration crop irrigation. In view above, objective this study was to evaluate phytomass accumulation and production components colored cotton genotypes during different development stages, under conditions salinity, plants grow...

Genetic evaluation of segregating populations is one the primary activities cotton breeders. Seven genotypes were crossed in a line ? tester mating design. The population 12 F1, F2 and their parents tested Randomized Complete Block Design with three replications at Nazilli Cotton Research Institute T?rkiye during 2014/2015 cotton-growing season. genetic variability was significant for all chara...

Choosing suitable varieties and manipulating plant population are crucial management aspects in any cropping system that goals to improve yield, quality the balance between demand environmental resource availability. A two-year field experiment was conducted at Tehran, Iran, a split plot design replicated thrice examine effect of planting density (low, moderate high) on ten cotton genotypes. In...

Cotton plants contain suites of phytochemicals thought to be important in defense against herbivores, some of which are localized in pigment glands which contain gossypol and other terpenoid aldehydes. The simple genetic basis for the expression of these glands has led to the development of near-isogenic glanded and glandless genotypes. Glands may also be phenotypically induced by herbivory. We...

in order to study of combining ability and heterosis in cotton (gossypium hirsutum l.), six hopeful genotypes were crossed in a half-diallel scheme at gonbad research station. fifteen f1 hybrids along with six parents were grown in randomized complete block design with 3 replications, in 2004. combining ability estimates were calculated according to method 2, model 1 of griffing (1956a,b). rela...

Cotton is an important crop in the world and is a major source of oil for human consumption and cotton meal for livestock. Cottonseed nutrition (seed composition: protein, oil, and minerals) determines the quality of seeds. Therefore, maintaining optimum levels of cottonseed nutrition is critical. Physiological and genetic mechanisms controlling the levels of these constituents in cottonseed ar...
