Description
A collection of 137 accessions of tropical and subtropical grasses of Pennisetum purpureum (53), Panicum maximum (10), Brachiaria spp. (9), Hemarthria altissima (19), Setaria spp. (11), Digitaria spp. (22), Cynodon spp.(7) and Paspalum spp. (6) was evaluated for frost tolerance (FT), dry matter yield per cut (DMYC), number of cuts (NC) and accumulated dry matter yield per year (ADMY). Crude protein content (CPC), leaf/stem ratio (L/S), pubescence (P) and animal preference under grazing (AP) were also recorded in 20 entries of in P. purpureum. Data exploration involved cluster analysis and ordination, revealing the most promising entries among and within genus. In general ADMY and FT were the most important variables to discriminate entries. Pennisetum, Panicum and Hemarthria were the most productive genus with high FT. Cynodon and Paspalum showed high FT.
