detailed investigation on the molecular mechanism of heat tolerance in tomato. Heritability analysis is important to determine the appropriate method of genetic improvement. Heat stress tolerance was found to have low heritability ( Hanson et al., 2002

crucial to the plant breeder in determining the potential application of the material such as for turf ( Wright et al., 1983 ). Genetic variation and heritability estimates help predict the response to selection for desired traits ( Dudley and Moll, 1969

Fraser fir established in 1983 found significant differences among sources and among families within seed sources for all traits measured ( Arnold and Jett, 1995 ; Arnold et al., 1994b ; Jett et al., 1993 ). Heritabilities for most traits important in

of inheritance of fruit softening. Resemblance among relatives is a basic genetic phenomenon, and the degree of resemblance determines heritability, which in turn facilitates the choice of a breeding method for use in genetic improvement ( Falconer
