Abstract

Pathogen efficient analysis study was conducted under normal (EC"1.76dSm-1) and saline conditions (EG 15.30 dsm-r) on four sunflower inbred lines and tireir possible single crosses excluding reciprocals. Path coefficient analysis revealed that head diameter followed by 100-achene weight, made the highest direct contribution to achene yield under normal condi tions. Head diameter followed by K+ concentration in young growing leaves showed the highest direct effect on achene yield under saline conditions. Therefore, it is suggested that selection criteria would be different under normal and saline conditions to improve achene yield. Selection could be based on genotypes having large head diameter and higher 1O0-achene weight, under normal conditions, whereas, on large head diameter and high K+ concentration imposing restriction on Na+ concentration in young growing leaves, undér saline conditions.

Keywords: Path analysis, Helianthus annuus L., saline conditions, fieldexperiment, selection criteria, salt tolerance.
