GENETIC ANALYSIS FOR MORPHOLOGICAL TRAITS OF EUPHORBIA HELIOSCOPIA

Abstract

Euphorbia helioscopia is a weed plant that grow in the filed of cop plants and caused yield losses through competition for water, mineral salts and nutrients. It is also grown as medicinal plant to extract various drugs. Prescribed study was conducted to access the genetic variability for morphological traits of Euphorbia helioscopia under four different locations/environmental conditions. It was found that the higher and better performance was predicted under location 4 a compared with other locations. Higher and significant correlation was recorded between fresh weight, leaf area and plant height. Regression analysis predicted that higher contributing traits were fresh inflorescence weight and dry weight. It was suggested from results that the plant population of Euphorbia helioscopia should be controlled to minimize yield losses in crop plants.
