Correlation studies in tomato (Solanum lycopersicum L.) for yield and quality

Abstract

A total of 45 experimental hybrids generated by diallel mating design using 10 inbred lines of sweet corn were evaluated with 10 parents and 2 checks during Rabi 2010-11 at Vegetable Research Station, Dr. Y.S.R. Horticultural University, Rajendranagar, Hyderabad. The yield per hectare displayed positive correlation with plant height, No. of primary branches/plant, No. of flowers/cluster, No. of fruits/clusters, fruit length, fruit width, average fruit weight, No. of locules/fruit, pericarp thickness, total soluble solids, titrable acidity, total sugars, lycopene content. Higher correlation coefficient was observed between fruit yield and No. of flowers/cluster and No. of fruits/cluster. Since plant height, number of flowers per cluster, number of fruits per cluster, total soluble solids showed highest significant positive correlation with yield selection for these characters will be beneficial for improving the yield in tomato without compromising for quality.
