Summary
It has been found that complete resistance of the strawberry cultivars and selections Earliglow, Guardian, MdUS 2700, MdUS 2929, MdUS 3816 and Redchief to Phytophthora fragariae is inherited in a one-to-one ratio, suggesting that these genotypes have one major resistance gene effective to the races present in the test field.
The high level of partial resistance of Cambridge Favourite has clearly been recovered in its progenies. However, from results presented here, no conclusions could be drawn with regard to the number of genes involved in the partial resistance of Cambridge Favourite. It is, however, suggestive that about half the susceptible selections derived from crosses with Cambridge Favourite have shown a relatively high level of partial resistance. The selections concerned were obtained by selection on horticultural characters in seedling populations planted on an uninfested field.
