Registration of three germplasm lines of cotton derived from Gossypium barbadense L. accession GB713 with resistance to the reniform nematode. Journal of Plant Registrations. 7:220-223.

Interpretive Summary: Three reniform nematode resistant cotton germplasm lines, M713 Ren1, M713 Ren2, and M713 Ren5, were developed and jointly released by USDA-ARS and the Mississippi Agricultural and Forestry Experiment Station. The three germplasm lines were derived from a cross between Sure-Grow 747 and GB713, a photoperiodic accession, and subsequent back crossing to Sure-Grow 747. Egg production of the reniform nematode was suppressed approximately 90 percent of a susceptible check in greenhouse tests. Marker assisted selection was successfully used to develop these resistant lines which should be valuable to cotton breeding programs.

Technical Abstract: Three reniform nematode, Rotylenchulus reniformis Linford and Oliveria, resistant upland cotton, Gossypium hirsutum L., germplasm lines, M713 Ren1, M713 Ren2, and M713 Ren5, were developed and jointly released by USDA-ARS and the Mississippi Agricultural and Forestry Experiment Station. The day-neutral reniform resistant germplasm lines originated from the photoperiodic G. barbadense L. accession GB713 and were selected using tightly linked SSR markers. Egg production of the reniform nematode was suppressed approximately 90 percent of a susceptible check in greenhouse tests. The lines exhibit considerable differences for agronomic and fiber traits and their high level of resistance should be valuable to cotton breeding programs. The successful use of marker assisted selection for these specific SSR markers further validate their use in selection of resistant plants in segregating generations.
