Abstract:

In the present study, correlation and path coefficient analysis with 19 yield and yield attributing characters was carried out in 27 genotypes of vegetable amaranth in Randomized Block Design with 3 replications at Vegetable Research Farm, College of Horticulture, Rajendranagar, SKLTSHU, Hyderabad during Rabi, 2016. Highly significant and positive correlation with foliage yield was observed with plant height at 30 and 60 DAS, stem diameter at 60 and 90 DAS, stem weight per plant, leaf length, leaf width, leaf area index, leaf weight per plant and leaf stem ratio at 30, 60 and 90 DAS, total  chlorophyll content, protein content, ascorbic acid, moisture content and folic acid, whereas number of branches at 30, 60 and 90 DAS and number of leaves at 60 and 90 DAS showed negative association with foliage yield. Path coefficient analysis revealed that the characters like plant height (60 DAS), leaf weight per plant (30, 60 and 90 DAS), protein content had high to moderate positive direct effect on foliage yield per plant and these traits recorded significant, positive correlation with foliage yield per plant. It clearly indicates that direct selection based on these characters would be effective for an increase in foliage yield.
