Using near infrared reflectance spectroscopy for estimating nutritional quality of Brachiaria humidicola in breeding selections

Agrosystems, Geosciences &Environment, Volume 3, Issue 1, 2020., 2020
Abstract Brachiaria humidicola (BH) (syn. Urochloa humidicola) is an important forage grass in the tropics due to its capacity to grow in nutrient‐deficient soils, tolerate waterlogging, and inhibit soil nitrification. A major objective of BH breeding is to improve its nutritional quality. Therefore, a rapid and low‐cost method is needed to assess main

Visual selection of Urochloa ruziziensis genotypes for green biomass yield

Acta Scientiarum. Agronomy, 2019
The breeding program of Urochloa ruziziensis evaluates many genotypes in initial phases. Evaluations through grades might make the selection less costly. The aim of this study was to verify the efficiency of visual selection for green biomass yield in relation to different selection strategies, such as mass selection by phenotypic mean, BLUP (Best ...
