“…The relatively high root surface area and volume of the Catuaí IAC 62 and IPR 100 cultivars resulted from the intensive selection of breeding programmes and make them successful cultivars for growers compared with progenies that have yet to enter the market. Sera et al (2017) and Martins, Pedroso, Fazuoli, and Gonçalves (1992) demonstrated the high potential for the production of Catuaí 62 and IPR 100, highlighting them among other cultivars in the field. Nevertheless, when a field is infested by M. paranaensis, the yield potential of Catuaí 62, indicated by the robust root system, is decreased due to a reduction in the root surface.…”

Climate change greatly influences coffee production, especially in areas infested with plant‐parasitic nematodes. In this study, coffee genotypes showed differences in their morphological and physiological characteristics when subjected to a water deficit and parasitism by Meloidogyne paranaensis. The cultivar IPR 100 had the largest superficial and volumetric root system area, even when parasitized. The two progenies (MG 0179‐1 and MG 0179‐3) and the cultivar Catuaí IAC 62 had a similar surface area (p < .05) when parasitized. However, the root surface area and volume of MG 0179‐3 increased by 96% and 400%, respectively, when parasitized by M. paranaensis. On the other hand, Catuaí IAC 62 had a 31% reduction in root surface area. Catuai 62 and IPR 100 showed higher sensitivity to drought when parasitized because of the increased photochemical sensitivity and reduction in photochemical quenching. In MG 0179‐1 and MG 0179‐3, an increase in non‐photochemical quenching occurred in response to stress, indicating that these progenies use a photochemical response to protect photosystem II. In this work, MG 0179‐3, which is resistant to M. paranaensis, was remarkable because, interestingly, the infestation caused an increase in its root surface area. In addition, MG 0179‐3 had relatively good photochemical performance under water deficit and M. paranaensis parasitism.

A coffee plant producing large fruit, seeds, and leaves in relation to conventional coffee plants, possibly generated by genetic mutation, was named Big Coffee VL. Seeds of this coffee plant were classified by size and used to establish the crop, whose progenies were designated as Big Coffee VL. large, Big Coffee VL. medium, and Big Coffee VL. small. The aim in this study was to investigate desiccation tolerance, together with size classification, and evaluate the physiological quality of the seeds of this progeny. Seeds of each type of Big Coffee VL. and of the cultivar Topázio were collected. High moisture seeds and seeds dried to 11% moisture content were evaluated to assess desiccation tolerance. Dried seeds of each Big Coffee VL. progeny and of the Topázio cultivar were classified by size in sieve testing using oblong screens for separation of peaberry seeds, and circular sieves from 22 to 12 for separation of flat seeds. All seeds were subjected to physiological evaluation through the germination test and determination of seedling dry matter. A completely randomized experimental design (CRD) was used; results were subjected to analysis of variance and means compared by the Scott-Knott test. Big Coffee VL. seeds tolerate desiccation to moisture content of 11% wet basis. Seeds of the Topázio cultivar have better physiological performance than seeds of the Big Coffee VL progenies. The bigger the seeds of Big Coffee VL., the better their physiological performance, exhibiting greater seedling dry matter.

“…Destacaram-se, no quarto biênio, as progênies 1189-9-80-1, 1189-12-106-1, 1189-12-52-2, 1190-11-8-4, 1190-2-16-2, 1190-2-7-1, 1189-9-80-3, 1190-2-128-4 e 1189-9-5-2, com produtividades variando entre 73,70 e 87,4 sc ha -1 , superando os cultivares utilizados como testemunhas. Essa diferença de produtividade entre os biênios pode ser atribuída às variações edafoclimáticas, dos locais, e climáticas, dos biênios, utilizados para a formação dos ambientes no presente estudo (Carvalho et al, 2008b;Gichimu & Omondi, 2010), resultando em mudanças fisiológicas, como metabolismo de carbono ou reação para déficit hídrico ou outros tipos de stress (Cilas et al, 2010;DaMatta et al, 2003DaMatta et al, , 2002 Na literatura, é indicada a necessidade de avaliação da produção por pelo menos quatro safras consecutivas, ou dois biênios, para ter sucesso na seleção de uma progênie, visto que se trata de uma cultura perene e a estabilidade de produção é alcançada na quarta colheita (Carvalho, 1989;Fazuoli 1977;Martins 1989). Portanto, o ciclo de avaliação utilizado neste estudo foi suficiente para discriminar, com eficiência, o potencial produtivo das progênies.…”

Agronomic performance of coffee F 4 progenies from the cross between cv. Mundo Novo x cv. CatuaíCoffea arabica L. is cultivated in all Minas Gerais producing areas, with predominance of cv. Catuaí and cv. Mundo Novo, owing to their high plant vigor, yield and cup quality. This work aimed to evaluate the agronomic performance of coffee in the Epamig Experimental Farm, Três Pontas, MG, Brazil. The experiment used 39 progenies, in the fourth generation of selfing, after the second self-backcrossing of cvs Catuaí and Mundo Novo. (recurring progenitor) developed by Epamig coffee breeding program. The cultivars Catuaí Vermelho MG 99, Rubi MG 1192 and Acaiá Cerrado MG 1474 were used as control. The following parameters were evaluated: yield of eight harvests (1997/1998 to 2004/ 2005), vegetative vigor, floating grains percentage, and bean size. The results showed that there is genetic variability among the progenies studied. The seventh and eighth harvest produced the highest yields. Progenies 1189-9-80-1 and 1189-9-80-3 showed good performance for the evaluated characteristics and will be selected for future works of genetic breeding. (1998/1999 a 2005/2006), vigor vegetativo, percentagem de frutos chochos e classificação quanto à peneira. Ficou evidente que existe variabilidade genética dentro do grupo de progênies estudadas. As maiores produtividades foram encontradas na sétima e oitava colheita. As progênies 1189-9-80-1 e 1189-9-80-3 apresentaram melhor desempenho, em todas as características avaliadas e serão selecionadas para futuros trabalhos de melhoramento genético, sendo lançadas como cultivar ou utilizadas em hibridações.Palavras-chave: café, melhoramento, produtividade, vigor vegetativo.
