Interpretive Summary: Three, upland cotton germplasm lines, moderately resistant to the reniform nematode, MT2468 Ren1, MT2468 Ren2, and MT2468 Ren3 were developed and jointly released by USDA-ARS and the Mississippi Agricultural and Forestry Experiment Station in 2011. The germplasm lines originated from the primitive accession T2468. Resistance to reniform nematode suppresses reproduction approximately by one-half of that of 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.

Technical Abstract: Three reniform nematode, Rotylenchulus reniformis Linford and Oliveria, moderately resistant upland cotton, Gossypium hirsutum L., germplasm lines, MT2468 Ren1 (Reg. No. ________, PI ________), MT2468 Ren2 (Reg. No. ________, PI ________), and MT2468 Ren3 (Reg. No. ________, PI ________), were developed and jointly released by USDA-ARS and the Mississippi Agricultural and Forestry Experiment Station in 2011. The day-neutral germplasm lines originated from the photoperiodic G. hirsutum accession T2468. Resistance to reniform nematode suppresses reproduction approximately by one-half of that of 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.
