Assessment of yield, yield related traits and quality properties by correlation coefficients and cluster analysis in some tomato lines

In order to evaluate yield, yield-related traits and fruit quality in 83 tomato lines, this experiment was conducted using Completely Randomized Block Design with three replications. Results of analysis of variance indicated highly significant genotypic differences for all studied traits. Fruit yield showed a positive and highly significant correlation with average of fruit number and weight, fruit length and diameter, pericarp thickness and titrable acidity (TA), and negative significant correlation with days to 50% maturing and ripening index (TSS/TA) traits. Cluster analysis classified all lines in five groups and there was highly significant difference among the clusters for all traits except TSS. Based on mean comparison between cluster analysis groups, the lines in cluster 5 including, 282, 276, 244, 213, 247 and 412 were early maturing and had a high value of yield related traits. Among the cluster 5 lines, some of them had a high titratable acidity and length to diameter ratio, and a lower TSS/TA than other line. These lines could introduce as suitable lines for fresh consumption and also for processing as a result of their long shelf life and could be used for production of suitable hybrids.
