abstract={Reniform nematode (<i>Rotylenchulus</i> <i>reniformis</i>) is a serious pathogen of cotton in the United States and management has been difficult due to the lack of resistant upland cotton (<i>Gossypium</i> <i>hirsutum</i>) varieties. The diploid <i>G</i>. <i>arboreum</i> germplasm line PI 529728 was identified as a potential new source of <i>R</i>. <i>reniformis</i> resistance. Line PI 529728 was crossed with the highly susceptible <i>G</i>. <i>arboreum</i> germplasm line PI 529729 to develop F<SUB>1</SUB>, BC<SUB>1</SUB>F<SUB>1</SUB>, and F<SUB>2</SUB> populations that were screened for nematode resistance under controlled environmental conditions to determine the genetics of resistance. The 10 F<SUB>1</SUB>, 69 BC<SUB>1</SUB>F<SUB>1</SUB>, and 332 F<SUB>2</SUB> plants were inoculated with 1,000 vermiform nematodes and the number of swollen females on the root systems was determined 28 days after inoculation. The F<SUB>1</SUB> plants supported more nematodes than the susceptible control genotype PI 529251 (<i>G</i>. <i>hirsutum</i> accession Deltapine 16) indicating resistance was a recessive trait. For the BC<SUB>1</SUB>F<SUB>1</SUB> and F<SUB>2</SUB> populations, plants supporting the same or a reduced level of infection that developed on the resistant control genotype PI 163068 (<i>G</i>. <i>barbadense</i> accession Texas 110) were rated as resistant. Based on this classification of resistance and susceptibility, it was predicted that a single recessive gene was conferring resistance; although, the BC<SUB>1</SUB>F<SUB>1</SUB> population had more susceptible plants than expected. Additionally, highly resistant plants were observed in the BC<SUB>1</SUB>F<SUB>1</SUB> and F<SUB>2</SUB> populations. This information will aid in the introgression of <i>R</i>. <i>reniformis</i> resistance from PI 529728 into upland cotton for the development of resistant varieties.},
