“…As for the AUCSPC, there was no significant difference between genotypes (Figure 4). These data support Gomes et al (2015) who did not find a significant effect to the cercoporiosis in the selection of breeding progenies between the cultivars of the Icatu and Catuaí coffee. Such data are similar to those found by Carvalho et al (2013), in which the progenies evaluation of the Yellow Catuaí IAC 2077-1-2-12-70 and Mundo Novo IAC 515-20 in the first year after the framework pruning, obtained average productivity of 70.95 sacs ha -1 .…”

In this paper, we aimed at selecting genotypes of Coffea arabica L. that are responsive to framework pruning, with high productive potential and desirable agricultural features. We evaluated 18 progenies in the F 5 generation, 8 of them being from the group Catucaí (breeding of seedlings of Red Catuaí with coffee seeds of the Icatu germplasm) and ten descendants from the Timor Hybrid (breeding of the Red and Yellow Catuaí with the Timor Hybrid), as well as two commercial cultivars as control (Tupi IAC 1669-33 and Obatã IAC 1669-20). The experiment was carried out at the experimental field of the Federal University of Lavras. The coffee was pruned in August 2014 after the sixth crop and once again in August 2016, being two cycles in the "safra zero" system. The design used was in randomized blocks (RBD) with three repetitions and 20 treatments (18 progenies and two commercial cultivars) totaling 60 experimental plots. We evaluated the area under the progress curve of incidence and severity of leaf rust and cercosporiosis, the productivity (sacs ha-1), sieve #16 and over (%), mocha-type grains (%) and apparent specific mass of grains (tonm-3). The genotype 12 (H516-2-1-1-18-1-4) was responsive to the framework pruning and kept its productivity stable in both pruning cycles, being efficient in such system of crop conduction, besides presenting low incidence and severity of coffee leaf rust and cercosporiosis and high sieve.

“…The second stage of the experiment was performed in the Laboratory of Bromatology of the Federal Institute of Education, Science and Technology of the South of Minas Gerais -Campus Muzambinho, from August to December 2013. limiting in colder regions exposed to wind, such as in the Brazilian states of Paraná, São Paulo and South of Minas Gerais, especially in young and pruned coffee plantations and in nurseries (GOMES et al, 2015).…”

Brazil stands out as the world's largest coffee exporter. However, in the cold and windy regions, such as the southern of Minas Gerais, have been undergoing attack of diseases, including the bacterial blight of coffee caused by the bacterium Pseudomonas syringae pv. garcae, which despite not having the same importance as the coffee leaf rust, is causing damages and losses to the coffee plantation. The control is mainly done through preventive measures such as installation of windbreaks. When bacterial blight of coffee is already installed, the chemical control is used with syrups of copper-based products and antibiotics. The aim of the present study was to verify the efficiency of the antibiotic kasugamycin associated with copper hydroxide in the control of bacterial blight of coffee and raw coffee beans quality. The experimental design was a randomized block with five treatments, four replicates and plots of 10 plants in the field where the treatments consisted of different concentrations of the kasugamycin: 0.0, 250, 500, 750 and 1000 mL ha -1 added with 1.0 L copper hydroxide. The percent analysis was performed on the raw beans in order to verify their physical and chemical quality. The obtained results demonstrate that the solution is efficient in the control of bacterial blight of coffee as well as in the improvement of vegetative vigor and production, but does not influence the quality of raw coffee bean.
