Determination of Genetic Variability, Correlation Coefficient, Heritability and Genetic Advance in Tomato (Solanum lycopersicon L.)

The present experiment “Determination of genetic variability, correlation coefficient, heritability and genetic advance in tomato (Solanum lycopersicon L.)” was carried out to study in 16 diverse genotypes of tomato during the year of 2013-14. The investigation was conducted at Horticulture Research Farm of Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-Vihar, Rae Bareli Road, Lucknow-226025 (U.P.) India. The spacing was maintained at 60 x 45 cm with the plot size 2.4 x 1.8 m 2 . The experiment was carried out under Randomized Block Design. The genotypes were used as experiment materials viz. Angoorlata, Arka Alok, Arka Abha, Arka Meghali, Arka Vikash, Azad Type-5, Kashi Amrit, Kashi Anupam, Kashi Hemant TKashi Vishesh, Pant Type-3, Pant Type-5, Pusa Gaurav, Pusa Hybrid-2, Pusa Upma and Pusa-120. The genotypes were collected from IIVR, Varanasi and GBPUA&T, Pantnagar. The twenty five characters of tomato ware observed viz. plant height, number of branches per plant (cm), plant spread (cm), number of leaves per plant, internodal length (cm), days to flower initiation, days to 50 % flowering, number of flowers per cluster, number of clusters per plant, number of flowers per plant, number of fruits per cluster, number of fruits per plant, 10 fruits weight (g), average fruit weight (g), number of harvest, total yield per plant (kg), fruit length (cm), fruit width (cm), polar diameter (mm), equatorial diameter (mm), pericarp thickness (mm), T.S.S. ( 0 B), number of locules, ascorbic acid (mg/100g) and acidity (%). Significant differences were recorded for all the traits. According to the present investigation, it may be concluded that wide range of variation ware found in tomato strain for all the traits studied. Among the all genotypes for most characters Kashi Amrit is highly significant viz. plant height, number of branches, plant spread, number of leaves, number of flower per cluster, number of fruit per cluster, number of fruits per plant, 10 fruit weight, average fruit weight, yield per plant, ascorbic acid and acidity.
