摘要：

The objective of this research was to characterise the degree of dominance of a soybean cyst nematode (Heterodera glycines) allele for incompatibility which interacts with a recessive soybean (Glycine max) allele for incompatibility to prevent the formation of cysts. Crosses of inbred nematode populations were made and the F, and F, populations evaluated for the numbers of cysts they could produce on several soybean lines. The nematode gene for avirulence interacts with the one recessive gene for resistance in soybean line PI 88287 and also appears to be recessive. This is the first example of a recessive‐recessive gene‐for‐gene interaction; genes for avirulence and resistance are usually dominant. The difficulties of doing definitive genetic studies with cyst nematodes are discussed. Copyright © 1990, Wiley Blackwell. All rights reserved
