GENETIC VARIABILITY IN CIRSIUM ARVENSE UNDER DIFFERENT ENVIRONMENTAL CONDITIONS

Abstract

Weeds are the plants that grow at all of the unwanted places. The plant population of weeds have to be controlled to reduce competition among crop plants and weeds. The prescribed study was conducted to evaluate Cirsium arvense growth under different locations/environmental conditions. The results showed that there was a positive and significant correlation among fresh weight, dry weight, plant height, fresh inflorescence weight, moisture contents and leaf area which shows similar findings from stepwise linear regression. GGE biplot showed location 4 as most favourable place for smooth growth and development of Cirsium arvense. It was suggested that the plant population of Cirsium arvense should be controlled through manual, chemical strategies while the use of transgenic crop plants (resistant to glyphosate) may be an advantage to control weeds
