Abstract/Description: | Twenty-two coloured grape accessions were screened for various physio-biochemical traits. The genetic variability and multivariate analysis were carried out for growth and biochemical parameters of grape accessions grown under Pune conditions. High genotypic and phenotypic coefficient of variations were observed in average bunch weight, berry weight, proline and total tannin. All the biochemical parameters showed very high estimated heritability for broad sense (h2 b.s.). Higher genetic gain was recorded for average bunch weight, total tannin, proline and protein while low genetic gain was observed in berry diameter and seeds/berry. The multivariate analysis revealed that biochemical parameters could be potentially used for discrimination of grape genotype. The heat map cluster analysis showed higher biochemical parameters in Kali Sahebi, Kishmish Maldovski, Red Ficosa, H-516 and Omania Black. Among the accessions studied, Kali Sahebi performed better concerning growth attributes like average bunch weight, berry diameter, berry and seed weight, days to harvest and biochemical constituents like total phenol, anthocyanin and colour intensity. A very close association was observed between phenotypic and genotypic variation, particularly for biochemical parameters. Therefore, very high heritability and genetic advance were recorded in these parameters. It can be concluded that the parameters governing the very close association between phenotypic and genotypic variation can contribute to the varietal selection and trait-specific varietal development programmes. |
