Abstract

Correlation studies were undertaken in seedling traits, morphological traits and among seedling and morphological traits under irrigated and drought conditions at University of Agriculture, Faisalabad during 1999-2000 to 2001-2002. Under normal condition, important correlations of fresh shoot weight, dry shoot and root weight with yield; primary branches with yield and days to first bud with maturity were found. These positive correlations might be used as selection criterion directly or indirectly for yield improvement under normal conditions. Under these conditions plant height had negative correlation with siliquae per plant, which signified short stature plant with minimum vegetative growth. Under drought, root length, fresh and dry root weight showed positive correlation with yield; plant height with siliquae per plant and yield per plant. Under these conditions negative correlation between reproductive period and yield led to develop early flowering and early maturity variety. These two traits may help incorporate drought resistance in genotype. In general, the correlations between traits were not altered under stress.
