Abstract:
Tomato (Solanum lycopersicum L.) an autogamous diploid (2n = 2X = 24) vegetable belonging to nightshade family (Solanaceae) is an important warm season vegetable, suitable for growing throughout the world. The yield of Indian Tomato falls short of the global average. To increase productivity, better varieties and hybrids must be developed. The type, extent, and transmissibility of genetic diversity as well as the degree of targeted character transmission all affect selection efficiency. Since yield has a complex character, improving it directly is challenging. To investigate the kind and extent of variability, correlation and path coefficient analysis between yield and yield-contributing characters, 30 genotypes and 4 checks of tomatoes were examined. The experiment's statistical analysis was set up using an Augmented-II design (Also known as an Augmented RBD), which was seeded in 3 rows and 5 blocks. All of the genotypes for the characters had significant differences, according to the analysis of variance. a stronger link between days to first and the positive. On a genotypic and phenotypic basis, there is a higher amount of positive association between the days to first flowering, days to 50% blooming, days to first fruit set, and days to first picking. At the genotypic level, a negative correlation between fruit production per plant and days till the first harvesting was discovered (-0.447*G). Genotypically, the quantity of fruits per plant (0.7386) and days to first flowering (-0.5494) had the greatest positive and negative direct effects on yield, respectively.
