Association Analysis of Yield and Fibre Quality Characters in Upland Cotton (Gossypium hirsutum L.)
Journal Title: International Journal of Agricultural Sciences and Veterinary Medicine - Year 2016, Vol 4, Issue 3
Abstract
Correlation and path coefficient analysis have been worked out for 17 characters in 55 genotypes of upland cotton. The correlation study revealed that seed cotton yield was found to be positively and significantly correlated with traits like no. of bolls plant -1 , boll weight, seed index, lint index, micronaire value and lint yield plant -1 at both phenotypic and genotypic levels. Path analysis revealed high positive direct effect of number of bolls plant -1 , boll weight and lint yield plant -1 on seed cotton yield plant -1 . Selection based on these characters would improve seed cotton yield. Due weightage should be given in selection process with more number of bolls plant -1 and more boll weight and there should be economic balance among these traits to get higher seed cotton yield plant -1 .
