SUMMARY
Self-rooted tomatoes ‘Ailsa Craig’ and ‘Kingley Cross’, and scions of ‘Ailsa Craig’ grafted on to different rootstocks, were grown in soil infested with different numbers of Heterodera rostochiensis (Mainly pathotype A). Three rootstocks (RS4, RSKN, ISKVF) tolerated damage from nematode populations of up to 125 eggs/g soil, but nematodes increased up to x45 on them. Two nematode-resistant F1 hybrid rootstocks, B6633 (ex Lycopersicon pimpinellifolium B6173) and B6015 (ex L. hirsutum var. glabratum B6013), tolerated up to 125 eggs/g soil; nematode populations declined as much as 80% under B6633, and increased little under B6015. On the self-rooted ‘Ailsa Craig’ and ‘Kingley Cross' the numbers of nematodes increased markedly (maximum increase x40), and greatly affected growth and yield so that initial populations greater than 62 eggs/g soil caused crop failure.
