Abstract

Correlation and path analysis were carried out in nineteen tomato genotypes for yield and quality characters. The association studies showed that fruit yield per plant was positively and significantly correlated with polar diameter of fruit, equatorial diameter of fruit, number of locules per fruit, individual fruit weight and Peanut bud necrosis virus (PBNV) disease incidence per cent. However, fruit yield per plant was negatively and significantly correlated with number of branches per plant, fruit set per cent, acidity, ascorbic acid and lycopene. Preferable negative correlation coefficient values were also recorded by days to first flowering and days to 50 per cent flowering with and without significance, respectively. Hence, direct selection for these traits can be done for improving fruit yield in tomato.
