| 0 | PI 691530 | 'Ace' | Vigna unguiculata (L.) Walp. | Texas, United States | PVPO | | Not Available | 2019 | DEVELOPED | | | | | | Cultivar | ‘Ace’ is a small seeded cultivar of forage cowpea (Vigna unguiculata [L.] Walp.) that was developed by Texas A&M AgriLife Research at Overton, TX. Mass selection within two variable plant introduction lines was used to develop Ace. Seed from five plants with very similar phenotypes, including first bloom in late August, were bulked and tested as TX-3 experimental forage cowpea. Biomass production of Ace (experimental designation TX-3) at Overton, TX was 2.8 and 4.7 MT ha-1 in 2013 and 2016, respectively. Biomass production of Ace at Vernon, TX in 2015, 2016 and 2017 was 3.9, 5.9 and 6.7 MT DM ha-1 , respectively. Protein content of Ace biomass at Vernon in 2015 and 2016 was 16.5 and 16.4, respectively. The seed size of Ace, expressed as seed weight, is 5.1 g 100 seed-1 compared to Iron & Clay at 10.6 g 100 seed-1. Average days to first bloom at Overton, TX for Ace and Iron & Clay are 87 and 114, respectively. Root galling of Ace by southern root-knot nematode (Meloidgyne incognita race 3) is very low and nematode reproduction is low, relative to southern root-knot nematode susceptible cowpea lines. | 2096647 | PI 691530 |
