Yield assessment of new streak-resistant topcross maize hybrids in Benin

open access: yesOpen Agriculture
Maize (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 ...

Selection of maize lines for estimating combining ability in topcrossings

open access: yesЗерновое 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

Topcross pearl millet hybrids for Africa: A case study for Mali

open access: yesExperimental Agriculture, 2022
Single-cross pearl millet hybrids are widely grown in India, but this cultivar type has not been adopted in Africa. Hybrids from India have proven to be highly susceptible to downy mildew disease in Africa, the continent where the disease originated.

Evaluation of the average performance of topcrosses among food and grain type soybean [PDF]

open access: yesBrazilian 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
