| Abstract | To understand the breeding potential of parental lines, we analyzed the combining ability and gene action of 10 quantitative traits in Lilium × formolongi. The clonal lines of three single cross F 1 s were crossed with the clonal lines of six testers to produce 18 three-way cross F 1 s in a Line × Tester mating design. The analysis of variance revealed that the mean sum of square of all genotypes was highly significant for all the traits studied. The crosses, parents, and cross vs. parent revealed significant differences among all traits studied, except the width of leaf, validating the combining ability. Furthermore, the Line × Tester analysis demonstrated that the lines, testers, and Line × Tester hybrids were significant for all traits studied, except the length of leaf and attitude of floral axis. The highest GCA (General combining ability) effect was observed for parent-1 45-3 (AF × Ad), with a positive GCA effect for the height of plant, diameter of stem, number of leaves, length of bud, and attitude of floral axis followed by parent-3 (Stu × Ad)-14 with significant GCA effects for the height of plant, number of leaves, length of leaf, width of leaf, and number of flowers. Tester-1 Jul-19 demonstrated significant performance for the length and width of leaf, days to flowering, length of bud, and attitude of floral axis. It can be used as a potential donor for both parent-1 45-3 (AF × Ad) and parent-3 (Stu × Ad)-14 for seed production with some important cut flower traits inside a green house. The diameter of stem, number of leaves, width of leaf, number of flowers, diameter of flower, and length of bud predominantly showed dominance variance, whereas the height of plant, length of leaf, days to flowering, and attitude of floral axis demonstrated additive gene action. Genotypic and phenotypic correlation coefficients demonstrated that plant height is highly correlated with the diameter of stem, number of leaves, length of leaf, and number of flowers and correlated with the attitude of floral axis. |
