| Abstract: | Summary Genetic analysis of cereal cyst nematode resistance in three genotypes of oats indicates that resistance in Avena sterilis I.376 is controlled by two dominant genes and in A. sativa cv. Mortgage Lifter by two recessive genes. Resistance in A. byzantina P.I. 175021 is dominant and monogenic, and is probably at a locus distinct from the resistance loci in the other two genotypes. |
