Potential of the ESA23B maize population for protein and oil content improvement
Scientia Agricola, 2003 Among the traits that may add commercial value to maize (Zea mays L.), those related to nutritional quality, specially protein and oil content, are of great interest to the feed industry. The objective of this work was studying the variability of protein

Genetic Distance Estimated by RAPD Markers and Performance of Topcross Hybrids in Popcorn
, 2012 The purpose of this study was to investigate the diversity of 14 popcorn populations and a broad genetic base tester using molecular RAPD markers and to estimate the correlation between the genetic distances and the performance of topcross hybrids.

<b>Breeding potential of S4 maize lines in topcrosses for agronomic and forage traits [PDF]
Acta Scientiarum. Agronomy, 2016 This study aimed to evaluate the performance of 46 maize lines (S4) obtained from crosses between the commercial hybrids Penta x P30F53 in topcrosses with the commercial simple cross hybrid Dow8460 (tester) and checks (hybrids Penta, P30F53, Dow8460 and Status).

The Effects of Heat Stress on High Oil Corn [PDF]
, 2005 High oil corn (HOC) is essentially dent corn that has been selected for high oil content in the scutellum. It is a value-added crop that can potentially offer a premium price for producers. Though southeastern U.S.

The Topcross Progeny Tests of Sires Used for Inbreeding in Poultry
Poultry Science, 1954 Abstract THE performance of his topcross progeny should give the best estimate of the breeding worth of an inbred male used for this purpose. Since inbreeding increases homozygosity, the value of topcrossing might be increased by mating the best cross-progeny tested males with their sisters.

Pesquisa Agropecuária Brasileira, 2006 O objetivo deste estudo foi avaliar, por meio de topcrosses, o potencial heterótico de 14 populações de milho pipoca. No ano agrícola 1997/1998, foram obtidos os híbridos topcrosses resultantes dos cruzamentos das populações com o testador, que se constituiu da mistura eqüitativa de sementes de todas as 14 populações.

Genetics and Molecular Research, 2016 The aim of this study was to identify inbred progenies of S0:1 maize (Zea mays L.) plants that were efficient at a low level of technology and responsive at a high level of technology through the use of topcrosses. Two contrasting environments were created using two levels of base fertilization and topdressing, so that the levels of nitrogen ...

AVALIAÇÃO DE LINHAGENS S2 DE MILHO EM TOPCROSSES COM LINHAGEM ELITE TESTADORA
Revista Brasileira de Milho e Sorgo, 2017 O objetivo foi avaliar o potencial de linhagens (S2) de milho em cruzamentos topcrosses, usando como testador uma linhagem elite. Foram conduzidos quatro experimentos, em que dois foram na região centro-sul do Paraná e dois na região noroeste de Minas Gerais.

Using scab resistant donors in apple breeding
Plant Protection Science, 2002 Apple cultivars were crossed according to the half-diallel and topcross mating design. Apple scab resistance of seedlings was estimated by using a 0-5 scale: 0 - no infection on leaves, 5 - more than 75% of leaf area infected.
