Genetic Variability, Character Association and Path Coefficient Analysis in Radish (Raphanus sativus L.)

MZ Ullah, MJ Hasan, AHMA Rahman, AI Saki

Abstract

Genetic variability, correlation and path coefficient analysis of yield and yield contributing traits in twenty one varieties of radish were studied. Root length, leaf length and root yield showed high genotypic coefficient of variation and heritability with high genetic advance in percentage of mean. The highest genetic advance was observed in root yield. Root yield had significant and positive correlation with days to harvest, root length and root diameter, and showed only positive correlation with plant height and leaf width. Path coefficient analysis revealed that plant height had the maximum positive direct effect on root yield followed by root diameter, leaf width and days to harvest.

Keywords: Genetic variability; radish; heritability; correlation; path analysis; root yield.
