Abstract

Abstract : A field study was conducted over a two-year period (2006-2007) at the Delta Research and Extension Center, Stoneville, MS, USA to screen selected entries in the 2006 Mississippi Cotton Variety Trials for tolerance to the reniform nematode ( Rotylenchulus reniformis ). Trials were conducted in nonirrigated fields with primarily sandy loam soils. Though some variability was noted between test locations and years, six of 13 cotton ( Gossypium hirsutum ) cultivars tested were considered tolerant to the reniform nematode: "Cropland Genetics 3520 B2RF, " "DynaGrow 2520 B2RF, " "Stoneville 5242 BR, " "Stoneville 5599 BR, " "Deltapine 488 BG/RR, " and "Fibermax 960 B2R." Of these, the first three exhibited yields similar to the productive cultivar "Deltapine 445 BG/RR" in all environments. Though they will not suppress the reniform nematode population, these cultivars can help reduce economic losses attributed to this pathogen in the Midsouth region of the USA.
