TAM RKRNR‐9 (Reg. No. GP‐941; PI 662039) and TAM RKRNR‐12 (Reg. No. CP‐942; PI 662040) with resistance to the reniform (Rotylenchulus reniformis Linford & Oliveira) and root‐knot [Meloidogyne incognita (Kofoid & White) Chitwood] nematodes are noncommercial breeding lines of upland cotton (Gossypium hirsutum L.) released by Texas AgriLife Research in 2010. Both lines were derived from the cross of the root‐knot nematode resistant line M‐315 RNR (G. hirsutum L.), and the reniform nematode resistant line Tx110 (G. barbadense L.). The resistance to reniform is moderate, suppressing nematode reproduction by 40–70%. The resistance to root‐knot nematodes is high, similar to that of the M‐315 RNR parent, with more than 90% suppression of reproduction and low amounts of root galling. This unique combination of resistance to the reniform and root‐knot nematodes makes these breeding lines valuable for cotton‐breeding programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
