Résumé
Correlation studies were undertaken in seedling traits, morphological traitsand among seedling and morphological traits under irrigated and droughtconditions at University of Agriculture, Faisalabad during 1999-2000 to 2001-2002. Under normal condition, important correlations of fresh shoot weight, dryshoot and root weight with yield ; primary branches with yield and days tofirst bud with maturity were found. These positive correlations might be usedas selection criterion directly or indirectly for yield improvement under normalconditions. Under these conditions plant height had negative correlation withsiliqua per plant, which signified short stature plant with minimum vegetativegrowth. Under drought, root length, fresh and dry root weight showedpositive correlation with yield ; plant height with siliqua per plant and yieldper plant. Under these conditions negative correlation between reproductiveperiod and yield led to develop early flowering and early maturity variety.These two traits may help incorporate drought resistance in genotype. Ingeneral the correlations between traits were not altered under stress.
