Description
Arrowleaf clover (Trifolium vesiculosum Savi) is a winter annual forage legume often overseeded on warm-season perennial grass pastures in the southern region of the United States. Bean yellow mosaic virus (BYMV) can reduce forage production, seed production and cause plant death of arrowleaf clover (Gibson et al., 1979; Pratt et al., 1982). Resistance to BYMV has been identified in red clover (Trifolium pratense) and the inheritance reported in detail (Taylor et al., 1986). A research program was initiated in 1985 to quantify the effects of BYMV on arrowleaf and to develop BYMV resistant arrowleaf germplasm through recurrent selection. Initial studies with half-sib arrowleaf families indicate variation for response to BYMV and potential for improvement through selection (Pemberton et al., 1988). This paper will give an overview of the recurrent selection program for BYMV resistance in arrowleaf clover.
