Genetic Analysis on Fruit Cut Cracking of Watermelon
Inheritance of fruit cut cracking was analyzed by using the joint segregation analysis of mixed genetic models of major gene plus polygene in six generations (PI, P2, Fl, Bl, B2, andF2) derived from two crosses of L-103 (fruit-cracking susceptible) ×X-101 (fruitcracking resistance). The cut fruit cracking was dominated by two major genes with additive-dominance-epistatic effects plus polygenes with additive-dominance effects(E-l model) in Cross X-101 ×L-103. The hereditability of major genes (hmx2) were 40.34％,, 25.08％. 33.10％ in Bl. B2, F2 population* and thai of polygenes (hpx2) detected in Bl. B2, F2population were 32.65％. 0. 50.20％. It also indicated that the environmental factors had a great effect on fruit cracking resistance as the environmental and genetic variance accounted for 39.55％ and 60.45％, on average, of the phenotypic variance, respectively.
