Partially inbred maize lines in topcrosses and hybrid performance [PDF]
Revista Ceres, 2020 In plant breeding programs, the selection of potential progenies in early generations of inbreeding is an essential step. Considering that, the adoption of topcrosses helps the breeder in the selection, this study aimed to verify the potential of S2 ...

Selection of maize lines for estimating combining ability in topcrossings
Зерновое хозяйство России, 2023 Hybrid maize breeding is carried out based on interline hybridization using heterosis in the first generation. Hybridization efficiency can be increased using parental forms with high combining ability in crosses. The purpose of the study was to identify

Evaluation of the average performance of topcrosses among food and grain type soybean [PDF]
Brazilian Archives of Biology and Technology, 2003 The food type soybean (exotic) are, in general, non-adapted to the Brazilian growing conditions. A breeding strategy to develop adapted food type soybean should involve crossing exotic with the available grain type genotypes. We evaluated the performance

Classical and AMMI methods to select progenies, testers and topcrosses hybrids in corn [PDF]
Revista Ceres, 2023 The objectives were to estimate the potential of S2 corn progenies for forage-related traits, and use of AMMI analysis to evaluate topcrosses compared to the classic analyzes.

Nitrogen use efficiency of open-pollinated maize cultivars and topcrosses under low nitrogen soil. [PDF]
HeliyonThe study was conducted to evaluate the nitrogen utilization efficiency (NUE) of open-pollinated maize cultivars under low nitrogen soil conditions. It took place at the Lower Niger River Basin Development Authority in Ilorin, Nigeria, during the 2019 and 2020 cropping seasons. The nitrogen treatments (0, 45, and 90 kg N ha⁻1) were assigned as the main

Performance and stability of maize topcross hybrids from partly inbred lines
Semina: Ciências Agrárias, 2017 Commercial hybrids are viable to generate base populations for obtaining new superior lines. Therefore, this study aimed to evaluate the performance and stability of maize topcross hybrids and select superior partly inbred lines.

Yield assessment of new streak-resistant topcross maize hybrids in Benin
Open AgricultureMaize (Zea mays L.) is the foremost cereal consumed in Benin but its production is constrained by the lack of access to high-quality seeds for intensification of the crop; hence, the continued cultivation of disease-susceptible, low-yielding, and open ...
