Info

There were six locations planted in 2012, all with a history of Verticillium wilt. Each site wasplanted with 32 entries, in plots that were 36 ft. long and 2 rows wide, with four replications pervariety, arranged in a randomized complete design. The hot weather in 2012 resulted in little tono wilt at three of the six sites, so the three sites that had sufficient wilt to impact yield will bepresented. These sites are Floydada, Plainview, and Garden City. The results were remarkablysimilar in terms of the top yielding varieties at each site. The following varieties yielded in thetop five at each of the Verticillium wilt sites that they were planted: Fibermax (FM) 2484B2F,FM 2011GT, FM 9170B2F, BX 1347GLB2, and NexGen 4111RF.141
