GENETIC ASSOCIATION AMONG MORPHOLOGICAL TRAITS OF LEPIDIUM DRABA

Abstract

Lepidium draba is a weed plant usually grown where the conditions are moist like road side, ditch banks, rang lands and pastures. It is a fast growing weed plant that competes with crop plants for water, mineral nutrients, light and plays as a hiding place for insects. The prescribed study was carried out to evaluate morphological traits of Lepidium draba under four different locations. It was found from results that plant fresh weight and moisture contents were relatively higher for under studied locations. There was a strong and significant correlation among fresh weight, dry weight, moisture contents and plant height. From regression analysis it was predicted that plant dry weight and moisture contents played an important role in improving fresh plant weight. GGE biplot showed location 4 as best environmental area for propagation of Lepidium draba. It was suggested from current study that the plant population of Lepidium draba to minimize yield losses in crop plants and reducing competition between Lepidium draba and crop plants.
