Registration of Soybean Germplasm Line DT97-4290 with Moderate Resistance to Charcoal Rot

DT97-4290 is moderately resistant to charcoal rot based on field evaluations from 2002 to 2004 in artificially infested sandy loam soil at Stoneville, MS. Host tissue colonization by M. phaseolina was assessed in three replications by destructively sampling 10 plants at the R7 growth stage (Mengistu...

Zusammenfassung:	DT97-4290 is moderately resistant to charcoal rot based on field evaluations from 2002 to 2004 in artificially infested sandy loam soil at Stoneville, MS. Host tissue colonization by M. phaseolina was assessed in three replications by destructively sampling 10 plants at the R7 growth stage (Mengistu and Paris, 2003). DT97-4290 is resistant to southern stem canker (similar to resistant check cultivar Manokin), Soybean mosaic virus (Paris, 2003), and Races 2, 4, and 10 of Phytophthora rot caused by Phytophthora sojae MJ.
