TRAIT ASSOCIATION STUDIES FOR YIELD COMPONENTS IN TOMATO (SOLANUM LYCOPERSICUM L.)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 1
Abstract
Correlations and path coefficient were studied in 38 tomato (Solanum lycopersicum L.) genotypes for thirteen yield-contributing characters. The correlation coefficients were determined to find out the inter relationship among the characters studied. Yield plant-1 was found highly significant and positively with average fruit weight, fruits plant-1, locule number fruit-1, pericarp thickness, fruits cluster-1 and number of clusters plant-1. Strong association of these traits revealed that the selection based on these traits would ultimately improve the fruit yield. In order to obtain a clear picture of the inter relationship between yield plant-1 and its components, direct and indirect effects were measured using path coefficient analysis. Analysis revealed that a highest positive direct effect on fruit yield plant-1 was exhibited by average fruit weight followed by fruits plant-1, clusters plant-1, fruits cluster-1 and pericarp thickness. It would be rewarding to lay stress on traits like average fruit weight and fruits plant-1 in selection programmes for increasing the yield because they showed positive and significant association with fruit yield plant-1 in both the analyses of correlation and path-coefficient. Residual effect was low which indicated that characters included in this study explained almost all variability towards yield.
