Abstract:
Three upland cotton (L.) germplasm lines, MT2468 Ren1 (Reg. No. GP-944, PI 663908), MT2468 Ren2 (Reg. No. GP-945, PI 663909), and MT2468 Ren3 (Reg. No. GP-946, PI 663910), that are moderately resistant to the reniform nematode (Linford and Oliveria) were jointly developed and released by the USDA-ARS and the Mississippi Agricultural and Forestry Experiment Station in 2011. The day-neutral germplasm lines originated from the photoperiodic accession T2468. Resistance to the reniform nematode suppresses reproduction approximately by one-half of that occurring on a susceptible check. The lines exhibit considerable differences for agronomic and fiber traits, and their moderate level of resistance should be valuable to cotton breeding programs.
