Abstract

Two independent experiments were conducted under normal and saline soil conditions with an aggregate ECe of 15.50 dSm and pH of 8.23. Phenotypic and genotypic correlation coefficients were computed between various morphological and physiological parameters in both oçeriments independently. Phenotypic and genotypic correlation coefficients under nor ma-l and saline conditions for all the traits agreed very closely. This similarity was due to the control of experimental error. Under normal and saline conditions, almost all the parameters in the study showed positive correlation to achene yield, except days to flower, which was negative, and oil content and Na-concentration, which were non-significant under normal soil conditions, and days to flower and K- concentration in leaves were negative under saline soil conditions. All achene yield components showed positive association with each other under both soil conditions. The association of physiological parameters under saline soil is rather confusing. It is suggested that selection for high achene-yielding lines under normal soil conditions can be based on head diameter, achene setting percentage, 100-achene weight, and leaf area, and under saline soil conditions, selection should be practiced on the basis of yield components in early flowering lines.

Keywords: Helianthus annuus L., correlations, saline conditions, field study.
