Comment	Killing effect is dominant. Modifiers also appear to be involved as Luig (612 and unpublished) found variation among genotype ki/ki parents. Some F2 and F3 Sr11/sr11 plants from Yalta/Chinese Spring crosses segregated with less than 50% Sr11-phenotypes among the progeny indicating that killing extended to eggs as well as pollen. See 'Gametocidal Activity'.
