Historically, the primary objective of cotton (Gossypium hirsutum L.) breeding programs was to improve the quantity and quality of cotton fiber. Because of the added value of cottonseed and its many uses, including a feed and human food source, there is interest in developing cotton breeding programs that focus improvement efforts simultaneously on cotton fiber and seed. Genetic analysis of cot...

Information on the economic characters was derived from ninety-two varieties of soybean. Analysis of variance was carried out for the data recorded on plant height, nodes plant, branches plant, 100-seed weight, days to 50 % flowering, days to maturity, grain yield, oil and protein content. Results revealed highly significant differences among varieties for all the characters. High heritability ...

ewline"> Castor (Ricinus communis L.) is an oilseed species, which in southern Italy iscultivated as annual during the spring-summer period under irrigation, but in mosttemperate areas such as those of eastern coast of Sicily, it could be grown as semiperennial with no irrigation, by the adoption of autumnal sowings. A fieldexperiment was conducted in southeastern Sicily with the aim of assessi...

Seed oil is important not only for human and animal nutrition, but also for various industrial applications. Numerous genetic engineering strategies have been attempted to increase the oil content per seed, but few of these strategies have involved manipulating the transporters. Pyruvate is a major source of carbon for de novo fatty acid biosynthesis in plastids, and the embryo's demand for pyr...

sowing date is an important determinant of yield in canola. cultivation of winter rapeseed cultivars in semi arid regions of iran however it has high potential for production, but, mentioned cultivars are late maturity and this late maturity cause to that silique formation and seed filling periods mature in the same time with hot and dry weather condition. in contrast, spring rapeseed cultivars...

in order to investigate of the effects of water stress on seed yield and gas exchange and to evaluate the relationship between source and sink in sunflower azargol variety, a split-plot factorial field experiment was conducted in 2008. in this experiment, water stress (no irrigation from 30 days after sowing till ripening) and irrigation (irrigation at -3 bar soil water potential) were consider...

in order to evaluate the physiological indices in relation to the screening of spring safflower genotypes for drought tolerance and productivity, seed and oil yields and yield components were measured for five genotypes including local arak, local esfahan, sina, kh23 – 57 and goldasht. the study was conducted in a loam soil in east azarbaijan, iran, during three successive years (2005-2007)...

in order to assess the performance of two soybean cultivars produced in two regions including karaj and moghan to drought stress at reproductive stages and also the impact of drought stress on yield and its components, oil and protein percent, an experiment was conducted as a split factorial based on complete randomized block design in three replications in agriculture faculty of tarbiat modare...

Thirty mutant lines selected from 3 widely adapted genotypes of sesame viz. Rama, SI 1666 and IC 21706 (ten from each of the three genotypes), developed by induced physical (γ-rays) and chemical (EMS) mutagens, were evaluated against their respective control genotype for yield and its important attributes in M4 generation to reveal the ramification of mutagens for disclosing the magnitude of va...
