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.

Combining ability of recombined F4 papaya lines: a strategy to select hybrid combination
Scientia Agricola, 2020 : The growing demand for quality of papaya by the domestic and international markets requires the development of genotypes that are capable of incorporating traits, such as high yield and fruit quality. This study estimated the genetic parameters and the

Journal of Agronomy and Crop Science, Volume 209, Issue 1, Page 71-82, February 2023., 2023 Abstract Most maize production across the globe is rain‐fed, and production is set to be negatively impacted as duration and occurrence of droughts increases due to climate change. Development of water‐deficit tolerant maize germplasm has been a major focus for most breeding programmes.

Comparison among nine alfalfa breeding schemes based on actual biomass yield gains
Crop Science, Volume 61, Issue 4, Page 2355-2371, July/August 2021., 2021 Abstract The definition of efficient selection methods for biomass yield of alfalfa and other open‐pollinated forage crops has lagged behind, despite its crucial importance for breeders. This study, performed in northern Italy, aimed to compare nine breeding schemes encompassing the evaluation of replicated clones and half‐sib (HS), first selfing ...

Potencial discriminatório de três testadores em "topcrosses" de milho [PDF]
Pesquisa Agropecuária Brasileira, 2003 O objetivo deste trabalho foi determinar o potencial de três testadores endogâmicos elites a fim de avaliar e classificar 15 materiais genéticos para a síntese de híbridos. Quarenta e cinco híbridos mais quatro testemunhas foram avaliados em cinco ambientes, no ano agrícola 2000/2001, utilizando delineamento em blocos ao acaso, com três repetições ...

Fast‐tracking the evaluation of novel female candidate lines in CMS‐based hybrid breeding
Plant Breeding, Volume 140, Issue 3, Page 432-441, June 2021., 2021 Abstract Time‐ and resource‐efficient identification of promising lines is of utmost importance in hybrid breeding. Here, we present a novel approach to evaluate female candidate lines for single‐cross hybrids, which saves four to five generations by obtaining general (GCA) and specific combining ability (SCA) effect estimates prior to the ...

The estimation of the combining ability of sunflower lines
Зерновое хозяйство России, 2020 For the successful development of competitive sunflower hybrids, it is necessary to have a sufficient number of parental lines with valuable breeding traits and high combining ability. In the zone of insufficient moisture of the Rostov region, there were
