Gene action in interspecific crosses of tomato for fruit yield and important characters (Solanum section lycopersicum)
ND Vyas, BR Patel, RG Hadiya, AS Damor and DJ Parmar
Tomato is a pulpy nutritious vegetable of solanaceae family grown throughout the world. The nature of gene action in the inheritance of yield per plant and some was studied deploying generation mean analysis following 6 parameter models for parents, F1
generations of five interspecific crosses of tomato. The scaling tests indicated the presence of epistasis for all the characters in different crosses except plant height in family I, number of primary branches per plant in family I and family III, number of fruits per plant in family V, fruit yield per plant in family V, fruit length in family I, fruit girth in family I and pericarp thickness in family IV. Both principal gene effects, additive (d) and dominance (h) gene effects were found significant for plant height and number of primary branches per plant in cross combination I; for pericarp thickness in cross combination IV; for number of fruit per plant and fruit yield per plant in cross combination V. Both additive and non-additive gene effects were found significant for most of the characters in all the interspecific cross combinations.
