Genetic variability and selection parameters for yield and quality attributes in tomato.
TLDR
It is suggested that characters viz., minimum days to first fruit picking, more number of fruits/plant, average fruit weight, fruit size, plant height, number of primary branches/plant and extended harvest duration should be given priority over other traits for selecting high yielding genotypes.Abstract:
Thirty five genotype of tomato were subjected to study the genetic components such as variability, correlation and path coefficient analysis for growth, yield and quality attributes. Significant differences among the genotypes were observed for all the traits under study. The high values of genotypic coefficient of variability and heritability estimates associated with greater values of genetic gain were observed for juice - pulp ratio, fruit yield/plant, number of primary branches/plant, number of fruits/plant, average fruit weight, and titrable acidity. Correlation studies revealed that the economically important trait fruit yield/plant exhibited high positive significant correlation with fruit size, plant height, number of fruits/plant and number of primary branches/plant at both phenotypic as well as genotypic levels. The path co-efficient analysis revealed that days to first picking had highest positive direct effect on fruit yield followed by harvest duration, number of fruits/plant, average fruit weight, plant height and number of flowers/cluster. It is suggested that characters viz., minimum days to first fruit picking, more number of fruits/plant, average fruit weight, fruit size, plant height, number of primary branches/plant and extended harvest duration should be given priority over other traits for selecting high yielding genotypes.read more

Studies on genetic variability, heritability and genetic advance for yield and quality traits in Tomato (Solanum lycopersicum L.)
TL;DR: High heritability combined with high genetic advance indicates that additive gene action plays a major role in governing these traits and these traits can be improved by simple selection.

Correlations between yield and fruit quality characteristics of fresh market tomatoes
TL;DR: Positive values of the genotypic and phenotypic correlations revealed that FP influenced FN with high direct effect and significant positive correlation, and these traits may be included as the main selection criteria for tomato yield improvement.

Genetic Associations Analysis for Fruit Yield and Its Contributing Traits of Indeterminate Tomato (Solanum lycopersicum L.) Germplasm under Open Field Condition
Om Prakash Meena,Vijay Bahadur +1 more
TL;DR: Genetic information on characters associations for tomato germplasm under open field condition revealed that fruit yield was significantly and positively correlated with number of flowers per plant and fruit weight, and it was suggested that hybridization of genotypes possessing combination of above characters is most useful for obtaining desirable high yielding segregation.

Genetic variability and trait relationship in cherry tomato (Solanum lycopersicum L. var. cerasiforme (Dunnal) A. Gray)
TL;DR: Nine traits of 11 cherry tomato inbred lines exhibited a wide range of genetic variability indicating that improvement of high yield through selection is difficult, rather hybridization can be effective for improving the fruit yield/plant.

Variability studies in Brinjal (Solanum melongena L.) in Chhattisgarh plains
TL;DR: The highest estimates of heritability coupled with high genetic advance estimated for the average fruit weight and number of fruits per plant showed effectiveness of simple selection for improvement of these characters.
