How Hybrid Breakdown Can Be Handled in Rice Crossbreeding?

Frontiers in Plant Science, 2020
In crosses between genetically divergent parents, traits such as weakness and sterility often segregate in later generations. This hybrid breakdown functions as a reproductive barrier and reduces selection efficiency in crossbreeding.

Genomic analyses provide insights into breed-of-origin effects from purebreds on three-way crossbred pigs [PDF]

PeerJ, 2019
Crossbreeding is widely used aimed at improving crossbred performance for poultry and livestock. Alleles that are specific to different purebreds will yield a large number of heterozygous single-nucleotide polymorphisms (SNPs) in crossbred individuals ...

Reproductive behavior of Artemiafranciscana (Kellogg, 1906) from San Quintín, Baja California, Mexico

Ciencias Marinas, 1998
The reproductive behavior of two populations of Artemia is analyzed, one from San Quintín, Baja California, and the other from Yavaros, Sonora. In the interpopulation mating, altemating oviparous and ovoviviparous reproduction was observed, with the ...

‘Helete Güneşi’, a New Walnut Cultivar with Late Leafing, Early Harvest Date, and Superior Nut Traits

Agriculture, 2021
‘Helete Güneşi’ was selected among different genotypes obtained from crossing ‘Maraş 18’ × ‘Chandler’ in Turkey. The present study compares phenological and pomological traits of ‘Helete Güneşi’ with those of its parents so as to scale their performances.

Economics of Swine Crossbreeding Systems [PDF]

Journal of Agricultural and Applied Economics, 1979
Crossbreeding in commercial hog operations is widely practiced and has increased substantially in recent years. Perhaps the most important positive feature of crossbreeding is heterosis, i.e., the performance of crossbred progeny is superior to the average performance of the parents.
