Abstract


In diallel analysis widely used by plant breeders, WrvsVr graph gives important knowledge about the parents. In this graph, it’s possible to interpret distribution of dominant and recessive genes among the parents by investigating the relations between W*r=[Volo x Vr]1/2 parabola and unit slope regression line.

In this study, finding intercept of unit slope line and the values corresponding the two points where parabola is cut by this regression lineand dividing the distance between those points into four equal parts are given with a numerical sample in cotton.
