Quality traits in tomato

Phenotypic and genotypic correlation coefficient studies were carried out in recombinant inbred line population of Vaibhav x Anaga cross for yield and quality characters. The association studies showed that fruit yield/plant (kg) has positive correlation with plant height (cm), Average fruit weight (g), number of branches per plant, number of fruits per plant, total soluble solids and number of locules/fruit at both genotypic and phenotypic levels.

Tomato (Solanum lycopersicum Linn) is one of the most consumed vegetables in the world and is a dietary source of vitamin, minerals, and fiber, which are important for human nutrition and health. It is extensively grown throughout the world. Sodium Azide is a chemical mutagen that has become an important tool to enhance agronomic traits of crop plants. It is being used to produce resistance in various susceptible crops to improve their yield and quality traits against harmful pathogens.

General and specific combining abilities (GCA and SCA) were estimated using six lines of tomato (Solanum lycopersicum L.) and three testers and their F1 hybrids, bred in line x tester fashion. The present study revealed that none of the parent was best combiner for all the traits indicating differences in genetic variability for different characters among the parents. Line x tester effect was found significant for all the characters under the study except for plant height.

The experiment was conducted in Department of Horticulture, Agriculture College, Dharwad during the year 2017-18. Fifty crosses were evolved by crossing 10 females (lines) with five males (Testers) in line x tester fashion and were evaluated along with the parents and commercial check in randomized block design. Data was been subjected to line x tester analysis. Analyses of variance were found significant for crosses with respect to yield and quality parameters studied.

Genome Wide Association Studies (GWAS) have been recently used to dissect complex quantitative traits and identify candidate genes affecting phenotype variation of polygenic traits. In order to map loci controlling variation in tomato marketable and nutritional fruit traits, we used a collection of 96 cultivated genotypes, including Italian, Latin American, and other worldwide-spread landraces and varieties.

Tomato is one of the potential vegetable crops both under protected and open field conditions in mid hills of Himachal Pradesh. The production under protected as well as open conditions has suffered in mid hills of HP due to biotic and abiotic stresses. Among biotic stresses bacterial wilt caused by Ralstonia solanacearum is the most devastating disease under protected as well as open field conditions in mid hills of HP which reduces tomato yield to very low levels.

Tomato is one of the most popular and widely grown vegetables in the world which ranks next to potato. Although tomato is generally grown under irrigated conditions, its cultivation as a rainfed crop has gained importance particularly in semi-arid regions. It has been established that stress due to water deficit is a very important limiting factor at the initial phase of plant growth and establishment. Studies on physiological evaluation of tomato genotypes is limiting in the drought stress condition.
