Autores: Brancher,Thyana Lays; Hawerroth,Maraisa Crestani; Hawerroth,Fernando José; Kvitschal,Marcus Vinícius; Denardi,Frederico; Guidolin,Altamir Frederico.
Abstract  The objective of this study was to characterize the parents and respective populations of apple trees regarding S-alleles to confirm their genealogy and to evaluate the efficiency of the molecular markers used. Sixteen specific sets of primers were used for identification of apple S-alleles by PCR. Two segregating populations of the Epagri Apple Breeding Program resulting from crosses between ‘Fred Hough’ × ‘Monalisa’ and ‘M-11/00’ × ‘M-13/91’ were evaluated. The expected segregations are 1:1:1:1 for full compatibility and 1:1 for semi-compatibility, which can be confirmed by the X2 test. The ‘Fred Hough’ (S5S19) × ‘Monalisa’ (S2S10) cross proved to be fully compatible; and two triploids were identified among the hybrids as well. The ‘M-11/00’...

‘SCS425 Luiza’: new apple cultivar with medium chilling requirement and resistant to glomerella leaf spot (colletotrichum spp.)
Provedor de dados: Revista Brasileira de Fruticultura
Autores: Denardi,Frederico; Kvitschal,Marcus Vinícius; Hawerroth,Maraisa Crestani; Argenta,Luiz Carlos.
Abstract  Apple is one of the main agribusiness products of temperate-zone fruits in Southern Brazil. More than 90% of apple production is obtained from only two apple cultivars – Gala and Fuji and their mutations. These apple varieties are insufficiently adapted to the regional climate and ‘Gala’ and its mutations are also susceptible to glomerella leaf spot – GLS, currently the main apple disease in Brazil. ‘SCS425 Luiza’ cultivar was developed by Epagri / Estação Experimental Caçador, aiming to offer to the production chain an early apple variety better adapted to the environmental conditions of Southern Brazil and resistant to GLS. ‘SCS425 Luiza’ cultivar was obtained by artificial hybridization carried out in 2001 using the cultivars Imperatriz and...

ABSTRACT Improvement of quality-related traits of grains is a constant concern in white oat breeding programs, which challenges breeders to understand their dynamics. The performance of different genetic combinations must be thoroughly evaluated to make high nutritional quality cultivars available. This study aimed to estimate the heterosis on F1 and F2 generations, vigor loss, due to inbreeding, and correlation between the grain chemical components to understand the dynamics of these traits, considering two segregating oat progenies. The populations Albasul × UPF 15 (population 1) and IAC 7 × UFRGS 19 (population 2) were developed. Both populations showed transgressive segregant individuals. The combination Albasul × UPF 15 provided significant heterosis...

Provedor de dados: Bragantia
Autores: Silveira,Solange Ferreira da Silveira; Hawerroth,Maraisa Crestani; Luche,Henrique de Souza; Oliveira,Danyela de Cassia; Sousa,Rogério Oliveira de; Maia,Luciano Carlos da; Oliveira,Antonio Costa de.
A aveia branca (Avena sativa L.) é uma cultura que tem um papel importante no sistema de produção de grãos e integração lavoura-pecuária, no entanto, em algumas regiões brasileiras, o pleno estabelecimento e desenvolvimento dessa cultura, bem como o aumento de produtividade são inviabilizados pelo excesso de alumínio (Al) nos solos. A avaliação de caracteres de plântulas de aveia desenvolvidas sob cultivo hidropônico com adoção de solução nutritiva mínima pode ser eficiente para classificar genótipos sensíveis e tolerantes ao Al. Este trabalho objetivou avaliar o desempenho de 10 genótipos de aveia submetidos ao estresse por Al, baseando-se na análise da retomada do crescimento da raiz, com uso de solução mínima e identificando quais caracteres se mantêm...

ABSTRACT: The stay-green character has been related to greater stress tolerance and yield through longer activity of the photosynthetic apparatus. Association of this character with grain yield may be linked to a network of features other than the grain mass. This study aimed to shed light on the actual contribution of stay-green character in Brazilian wheats and the associations between grain yield components in different environmental conditions. The experiment was conducted in a randomized block design with three replications in the years 2003, 2004 and 2005. Sibling lines with and without the stay-green character were evaluated analyzing the phenotypic correlation and path analysis separately by year and maturity group. Under favorable growing...
