The biology and ecology of cotton (Gossypium hirsutum) in Australia

Comparison of oil and fatty acid composition of seed, shoot and in-vitro regenerated organs of cotton (Gossypium hirsutum L. var. Sahel)

Cotton (Gossypium hirsutum L.) is a source of edible oil and fatty acids (FAs). In this study, embryos’ explants were cultured in MS medium with different concentration of  plant growth regulators (phytohormones) include BA, IAA, IBA, 2, 4- D and NAA, to finding the relationship of hormone and organogenesis with oil and FAs content. Oil was extracted with chloroform and methanol. FAs o...

CYTOGENETIC STUDY OF GAMMA IRRADIATED LINES OF COTTON (GOSSYPIUM HIRSUTUM L.)

A cytogenetic study was performed on M4 generation of gamma irradiated lines of Shirpan cultivar of tetraploid cotton (Gossypium hirsutum L.). A significant difference was observed in cytogenetical characteristics such as the number and type of quadrivalents as well as percentage of cells showing abnormality among the irradiated and non irradiated lines. Cytomixis and post- pachytene diffuse st...

Effect of Kinetin on Multiple Shoot Induction in Cotton (Gossypium hirsutum L.) cv. NIAB-999

Estimation of genetic parameters for quantitative and qualitative traits in cotton cultivars (Gossypium hirsutum L. & Gossypium barbadense L.) and new scaling test of additive– dominance model

A complete diallel cross of nine cotton genotypes (Gossypium hirsutum L. & Gossypium barbadense L.) viz Delinter, Sindose-80, Omoumi, Bulgare-539, Termez-14, Red leaf (Native species), B-557, Brown fiber and Siokra-324 having diverse genetic origins was conducted over two years to determine the potential for the improvement of yield, its components, oil and fiber qual...

Leaf area relationships to plant vegetative characteristics in cotton (Gossypium hirsutum L.) grown in a temperate sub-humid environment

Measurement or estimation of leaf area is essential for understanding crop responses to experimental treatments. The objective of this study was to develop regression models for estimating leaf area of field-grown cotton (Gossypium hirsutum L.) from measurements of leaf dry weight (LDW), vegetative components (stems and leaves) dry weight (VDW) and plant height (PH). Three cotton cultivars (Del...
