Correlation coefficients for yield and Path analysis in Crossandra genotypes for yield and its attributing traits

Abstract

The study was conducted at the Floriculture department, Horticulture College Munirabad, Koppal district. The experiment was designed in a Randomised Completely Block Design (RCBD) with ten genotypes. Flower yield exhibited a significantly positive correlation with the spike count per plant, number of flowers per spike, spike length, shelf life, leaf area, total chlorophyll, 100 flower weight, plant height, flower diameter, primary branches per plant and secondary branches per plant. At the same time, traits like days to fifty percent flowering and days to first harvest recorded the highest negative correlation with many traits. In the present investigation, the results of path coefficient analysis reveal that shelf life, total chlorophyll, number of flowers per spike, and plant height directly affect flower yield. Meanwhile, the flower diameter, and days to fifty percent flowering negatively affected flower yield.
