Abstract:
Tomato is one of the most important vegetable crops grown in India. We aimed to investigate the genetic variability, heritability, genetic advance, and correlation analysis for eleven yield and quality attributes. High heritability coupled with genetic advance was found for pericarp thickness, plant height, number of fruits per cluster, fruit length and fruit yield per hectare. Correlation analyses have been successful tools in developing selection criteria. Since increased fruit yield is an important goal in our tomato hybrid breeding program, we used correlation and path-coefficient analyses on fruit yield data. Fruit length, fruit width, chlorophyll content, pericarp thickness and number of seeds per fruit had a significant positive association with fruit yield quintal per hectare at both phenotypic and genotypic levels. Thus, selection for these characters could be considered as important selection criteria in improving hybrid tomato for high fruit yield per hectare.
