Character association for seed yield and yield traits in Saraca asoca (Roxb.) De Wilde

Abstract

An experiment was carried out to study the correlation and path analysis in six accessions of Saraca asoca at ICAR-Indian Institute of Horticultural Research, Bangalore during 2016-17. Correlation study revealed that the various parameters such as plant height, leaf length, leaf width, leaf area, pod length, pod width, number of pods per plant, number of seeds per pod, seed length and seed width had high significant positive correlation with seed yield per plant. According to path analysis, plant height, leaf length, leaf width, pod length and number of pods per plant had high positive direct effect on yield per plant. Leaf area, pod width, number of seeds per pod, seed length and seed width had negative direct effects on yield. Thus based on correlation and path analysis, the traits viz., leaf length, leaf width, pod length and number of pods per plant may be considered as selection indices for high yield.
