Abstract

The present research was undertaken to estimate variation and heritability of some morphological and biochemical traits of introduced Ethiopian mustard genotypes. The experiment was carried out in randomized complete block design with three replications at the University of Agriculture Peshawar during 2011-2012. Analysis of variance showed highly significant differences among Brassica Carinata lines for studied parameters. Phenotypic coefficient of variation and genotypic coefficient of variation ranged from 4.92-48.24% and 3.2-38.1%, respectively. The highest heritability values were recorded for pod length (0.83) followed by pods on main raceme (0.82). Genetic advance (as percent of mean) was the highest for seed yield plant-1 and pods on main raceme. Highly significant positive phenotypic correlation for seed yield plant-1 was observed with plant height and primary branches plant-1 whereas significant positive phenotypic correlation was observed with seed pod-1, while oil content was significantly positive correlated only with erucic acid. Carinata-29, Carinata-38, Carinata-45, Carinata-7, Carinata-47 and Carinata-83 were superior for seed yield and yield contributing traits, whereas Carinata-70 was the best for oil quality traits. On overall basis, carinata-70 and carinata-83 were the best lines hence could be used in breeding programs.
