Abstract:

The present experiment was carried out to investigate yield and quality traits in tomato, in order to generate information regarding the extent of genetic variability, heritability and genetic advance at Regional Research Station, Uchani, Karnal, CCS Haryana Agricultural University, Hisar, Haryana during autumn seasons of 2016 and 2017 involving 43 genotypes. The analysis of variance indicated significantly higher difference among the treatments for all the traits studied indicating presence of substantial amount of genetic variability among the materials studied. Analysis of coefficient of variation inferred that, the magnitude of phenotypic coefficient of variation (PCV) was slightly higher over genotypic coefficient of variation (GCV) for all the traits under study except specific gravity referring that they were much influenced by environmental factors. Further, the estimates of heritability and genetic advance were found higher for total fruit yield per plant, early fruit yield per plant, plant height, total number of fruits per plant and total soluble solids indicating scope of direct selection for improvement of these traits.
