To identify promising hybrids of the Megathyrsus breeding program [Megathyrsus maximus (Jacq.) B. K. Simon & S. W. L. Jacobs (= Panicum maximum Jacq.)], 20 apomitic hybrids pre-selected from a population of 80 F1 hybrids were evaluated. This F1 population comes from the cross between a sexual gen...

The population Bh16b was formed from the remnant seed of the best crosses identified from Bh16 population. As the intra-family variance in that trial was higher than the inter-family variance, and considering the constrains to develop a new Bh hybrid population, the breeder decided to take advant...

We aim to understand the magnitude of the interaction genotype by environment over several important traits, including those associated with nutritional quality, in a population of 100 hybrids of interspecific Brachiaria. In cooperation with Colombian National Agriculture Research Center (AGROSAV...

Two Genotypes of Brachiaria humidicola (A and B) were planted on the grounds of CIAT headquarters in Palmira during 2018 – 2019, 10 lamps were placed in the lot to evaluate 6 different photoperiods (1 - 6) with Light in 2 different wavelength range (W.R.) α and β, for this, 17 samples were carrie...

With the overall aim to build the foundation of a breeding program for Megathyrsus maximus, during 2019 we formed the crosses required for the study of genetic parameters following a factorial genetic design. The structure of the crosses was the following, nine male-parent candidates where establ...
