A survey was sent to 13 cooperating breeding and enhancement programs in 1995, to determine their needs. The top priorities for each enhancement category were: Insect resistance--Colorado potato beetle and aphid; virus--PLRV and PVY; fungi--late blight, early blight and Fusarium dry rot; nematodes--M. hapla and M. chitwoodi; bacteria--common scab and soft rot, and other traits--direct chipping, heat and drought resistance and 2n gametes. The breeding program goals remained essentially the same as in the 1990 survey, but with increased interest in ring rot, bacterial wilt, common scab, soft rot, late blight, Fusarium dry rot, blackspot/bruising, diploids, direct chipping, dormancy, and decreased interest in haploids and heat and drought resistance. Our goals will be altered to reflect the change in breeders/enhancers priorities, emphasizing late blight, cold chipping/frying, early blight, Erwinia and common scab. The last five years has been a learning and building process, laying a firm foundation for this cooperative mutual enhancement effort. |
