The practical value of obtaining estimates of general combining ability (GCA) from data accumulated in a breeding programme has been discussed by Gilbert (1967). In this study use has been made of data collected during the course of screening potato breeding material, derived from Solanum vernei Bitt. et Wittm., for resistance to the white potato cyst nematode, Qlobodera pallida (Stone) Mulvey & Stone, to assess the relative contributions of GCA and specific combining ability (SCA) by the procedure described by England (1974) which is based on Gilbert's (1967) method.

The white potato cyst nematode, Globodera pallida, was recently found in the USA and was identified using molecular and morphometric assessment. This paper examined some biological characteristics of the Idaho population of G. pallida. The samples of the original cysts showed that they had low rates of juvenile hatch and, consequently, low rates of reproduction when compared with glasshouse-reared populations. Virulence tests using sources of partial resistance from Solanum vernei and S. tuberosum ssp. Andigena CPC 2802 compared the Idaho population to European and South American populations of G. pallida. The Idaho population showed a virulence pattern comparable to other European populations in the Pa2/3 virulence group. The overall level of reproduction of the Idaho population on the resistant cultivars was the lowest of all the populations tested, suggesting that it is not highly virulent. These results are compatible with molecular characterisation, which indicates that this population is similar to the European gene pool.
