Performance of Different Cotton Varieties Under Two Row Spacings

Evaluation of seed cotton (Gossypium hirsutum L.) production and quality in relation to the different irrigation levels and two row spacings

The effect of row spacings and irrigation levels on the earliness of seed production of cotton was investigated under the Mediterranean environment of central Greece. This particular cotton growing area is exposed to risk of autumn rainfall that might cause low seed quality in fields allocated primarily for seed production. Two varieties of cotton, Celia and Hersi, were planted in two row spaci...

Performance of Selected Irradiated Cotton Varieties During M2 Generation

Dry seeds of four cotton varieties were irradiated with 0, 10, 15, 20 and 25 kR doses of gamma irradiation from Co source of gamma irradiation in 2012 at Nuclear Institute for Food and Agriculture (NIFA), 60 Tarnab, Peshawar, Pakistan. Three highly potential cotton varieties i.e. Gomal-93, Bt-131 and Bt-CIM-602 with irradiation of 15, 20 and 25 kR, respectively selected for the second year (May...

Indian Bt Cotton Varieties Do Not Affect the Performance of Cotton Aphids

Cotton varieties expressing Cry proteins derived from the soil bacterium Bacillus thuringiensis (Bt) are grown worldwide for the management of pest Lepidoptera. To prevent non-target pest outbreaks and to retain the biological control function provided by predators and parasitoids, the potential risk that Bt crops may pose to non-target arthropods is addressed prior to their commercialization. ...
