Narrative
M Rk-Rn 2 was developed by marker assisted selection. Reniform nematode, Rotylenchulus reniformis, resistance is associated with three QTLs, Ren barb1 and Ren barb2 located on chromosome 21 and Ren barb3 located on chromosome 18 (Gutierrez et al. 2011 Theo Appl Genet 122:271-280). The SSR markers CIR 316 and BNL 3661 are linked to root-knot nematode, Meloidogyne incognita, resistance (Gutierrez et al 2010 Theo Appl Genet 121:1323-1337. M Rk-Rn 2 is homozygous for SSR markers (GH 132_201, BNL3279_106, and BNL569_131) for the three QTLs (Ren barb1, Ren barb2, and Ren barb3) associated with reniform nematode resistance and is also homozygous for SSR markers CIR 316_201 and BNL 3661_285, which are associated with root-knot nematode resistance. Root-knot and reniform nematode resistance was verified in growth chamber tests. Most agronomic and fiber traits are equivalent to cultivars. Plant growth habit is similar to standard cutivars. M Rk-Rn 2 offers an excellent source of resistance to root-knot and reniform nematodes with acceptable agronomic and fiber traits.

Pedigree
Description:
M Rk-Rn 2 was developed from crossing M713 Ren1 (PI 665928) to M-240 RNR (PI 592511) and to 'Sure-Grow 747' SG747 (PI 656375). One plant was selected in the F2 of M-240 RNR x M713 Ren 1 via marker assisted selection (MAS). The SG747 x M713 Ren 1 F2 was MAS and 1 plant was selected. The selected plant from each population was crossed. The F2 was MAS and 1 plant was selected and crossed to SG747. The F2 was MAS and M Rk-Rn 2 was selected as a single plant and advanced to the F5.
