The reniform nematode is a serious pathogen of cotton growing regions of the U.S. The use of resistant varieties potentially could be the most economical and environmentally safe method to control the reniform nematode. However, information regarding the inheritance of resistance to the nematode is still limited. The objectives of this study were: 1) to determine the inheritance of resistance to the reniform nematode in an interspecific cross of Gossypium barbadense (GB-713) by Gossypium hirsutum (NemX). Growth chamber experiments were conducted during 2004-2005. The test included F1 and F2 generations from the cross, the resistant parent GB-713 (P1), the susceptible parent Acala NemX (P2), and their respective backcross generations, BC1P1, and BC1P2, that resulted from crossing parents with F1 plants. Results from the growth chambers will be discussed.
