The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

The experiment was carried out in a greenhouse from September 2001 to January 2002 to select several prickly-pear varieties resistant to cochineal carmine. Twenty pricky-pear varieties were evaluated as a completely randomized experimental design with four replicates. The plants were artificially infested. The infestation level was evaluated by a 0 – 5 scale. The most resistants clone are “Miúda” and “Orelha de Elefante”.

Figure 5
Dendrogram constructed using the UPGMA algorithm based on allele distances of each of the 74 individuals analyzed with five microsatellite markers.
The individuals belong to four sampling zones: (1) dam zone, (2) Huaynamota River zone, (3) central reservoir zone, and (4) southern reservoir zone.
