Breeding without breeding

open access: yesGenetics Research, 2009
SummaryAn innovative approach to tree breeding called ‘breeding without breeding’ (BWB) is presented. The method, as applied on the material in hand, allows the capture of 75–85% of the genetic response to selection attained through conventional programmes without the need to do any controlled pollination and simplified or possibly no experimental ...

Identifying and profiling the microRNAs associated with skin colour in the Muchuan black-bone chicken

open access: yesItalian Journal of Animal Science, 2020
MicroRNAs (miRNAs) are an abundant class of small non-protein-coding RNAs that regulate gene expression in plants and animals. Skin colour is an important economic consideration in chicken production, and chickens with black skin have high market value ...

Cassava Breeding I: The Value of Breeding Value [PDF]

open access: yesFrontiers in Plant Science, 2016
Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials-UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage.

Heritability of Unilateral Elbow Dysplasia in the Dog: A Retrospective Study of Sire and Dam Influence

open access: yesFrontiers in Veterinary Science, 2019
Canine elbow dysplasia is a significant health issue affecting many breeds. Unfortunately, treatments remain relatively limited, so control of this disease often falls to selectively breeding for dogs with normal elbows. The objectives of this study were
