Abstract
An investigation was carried out at Vegetable research farm of Banda
University of Agriculture and Technology, Banda, U.P. on the prescribed topic
“Assessment of genetic diversity for yield and fruit quality traits in Tomato (Solanum
lycopersicum L)” during late kharif 2022-23, with objective to estimate to assess genetic
variability for yield and fruit quality traits, to estimate correlation coefficient among yield
and fruit quality traits and to estimate genetic divergence among germplasm line for yield
and its component traits. Experimental material for the study consisted of 43 genotypes
including three checks i.e. Kashi Aman, Kashi Amul and Pusa Upkar. The experiment was
conducted in Augmented Block Design. Observations were recorded on 17 quantitative
and 5 qualitative traits viz., Days to 50% flowering, Plant hight (cm.) Leaf area (cm2
), Leaf
petiole length (cm), No. of primary branches, Number of flower per clusters, Number of
fruits per clusters, Days to 1st harvesting, Average fruit weight at marketable stage (g),
Total number of fruits at marketable stage, Polar diameter (cm), Equatorial diameter (cm),
Fruit size (cm2
), Pericarp thickness (mm), Locules per fruits, TSS (0B), Lycopene
(mg/100g), β-carotene (mg/100g), Ascorbic acid (mg/100g), Dry matter content (%), Yield
/ plant and Total yield (t/ha). Analysis of variance showed that highly significant for all
traits in treatments and for block showed non significant except 12 traits which significant.
A wide range of variation was estimates in the mean performance of genotypes for all traits
select the best genotypes according to Yield per plant were performance Banda Local-2
followed by Sel.-7, S.Naveen, Pusa-120, Kashi Amrit, Kashi Adarsh, EC-538408, EC538441 and LA-1800 were pick out for higher fruit yield to the best check Kashi Aman.
The moderate variation phenotypic as well as genotypic coefficients of variation were
observed in case of average fruit weight at marketable stage, yield per plant, total yield,
plant hight, leaf area, locules /fruit, fruit size, number of primary branches, Total number
