The inheritance of anther extrusion in two spring wheat varieties.

Anther extrusion was observed on two occasions under glasshouse conditions in two spring wheat varieties which showed different levels of expression of this character, and on F1 and F2 generations of reciprocal crosses between them. The results indicated that anther extrusion was controlled by few, possibly only two, genes with additive effects but had a low heritability. The association of pronounced anther extrusion and particular patterns of extrusion in the ear are suggested as the basis for rapid selection in glasshouse conditions for anther extrusion.
