The evaluation of genetic inheritance, heritability and correlations coefficient of mutant tomato
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2017, Vol 4, Issue 5
Abstract
The present study was evaluated genetic inheritance, heritability and correlation coefficient for some quantitative traits of tomato by using six generations (P1, P2, F1, F2, BC1P1 and BC1P2) from a cross between X604-1(P1) with indeterminate growth habit and the immature fruit have green shoulder with tomato TTD302A (P2) determinate growth habit without green shoulder. The results indicated that the analysis of mean values of plant characters in six population were found tomato X604-1 (P1) could be a good parental species, the development of yield were high. The study of heterosis were found highly significant related to plant height number of branches per plant and significant negative heterosis for days to 50℅ flowering, number of flower per cluster, number of fruit per cluster and average fruit weight. The correlation coefficient of variability was found positive significant in all of characters. Generation mean analysis were shown the influence of additive and dominant types of gene effect. However, both of gene effects were found mostly significant in all of plant characters, heritability in broad sense was observed high for all of the plan characters.
