Combining ability among provitamin A‐enriched maize inbred lines and heterosis of their hybrids for grain yield and agronomic traits

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Studying the combining ability of pro‐vitamin A enriched yellow maize inbred lines (Zea mays L.) provides valuable information on the breeding potential of these lines for developing high‐yielding and biofortified maize hybrids with desirable agronomic traits.

Inheritance of harvest index in common bean

Crop Breeding and Applied Biotechnology, 2018
The aim of this study was to verify if the harvest index (HI) of common bean is higher in modern lines, to verify if its estimate varies with the cycle of the plant and environmental conditions, and to obtain information concerning its genetic control ...

Indirect selection based on multispectral aerial images in the early stages of a wheat breeding program

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract To optimize a breeding program's phenotyping process, vegetation indices (VIs) obtained from multispectral images can serve as potential tools for the indirect selection of wheat (Triticum aestivum L.) families. This study evaluates the use of VI and multispectral bands for the indirect selection of superior families in the early stages of a ...

Diallel analysis of elephantgrass clones for bioenergy production in a tropical environment

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Climate change caused by fossil fuels has driven the search for bioenergy sources. Elephantgrass [Cenchrus purpureus (Schumach.) Morrone] biomass is a promising alternative for diversifying the energy matrix. One of the main steps of a genetic breeding program is the selection of parents who will form the crossing block, and the use of diallel

Selection of maize lines and prediction of hybrid and synthetic means using intergroup topcrosses

Crop Breeding and Applied Biotechnology, 2022
Topcrosses are routinely used in maize-hybrid programs. This study aimed to evaluate heterosis components and combining ability to predict hybrid means between synthetics from two groups of S1 maize lines using the intergroup topcrosses model that ...

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

New Plant Protection, Volume 3, Issue 1, March 2026.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Using genomic selection to examine subgenome dominance and epistasis in allopolyploid strawberry

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Allopolyploids are organisms that possess multiple sets of chromosomes derived from distinct ancestral species, resulting in multiple subgenomes. Many important crops are allopolyploid, including wheat (Triticum aestivum), cotton (Gossypium hirsutum), coffee (Coffea arabica), and strawberry (Fragaria × ananassa).

The augmented partial diallel cross [PDF]

Heredity, 1980
The augmented partial diallel cross is a design for estimating general and specific combining abilities in which one or more primary lines are crossed with all others, but the lines of secondary interest form a partial diallel cross. There are up to four variances of inter-line comparisons, depending on whether the lines are primary or secondary and ...

Influence of Ploidy and Genetic Background on Stress Tolerance of Intraspecific Yeast Hybrids

Microbial Biotechnology, Volume 19, Issue 3, March 2026.
A large set of intraspecific yeast hybrids was constructed using two strategies that yielded series of hybrids with variable ploidy. Phenotyping of the hybrids was carried out in high‐stress media to assess the effects of ploidy and genetic background on heterosis.
