WELFARE IMPLICATIONS OF WASHINGTON WHEAT BREEDING PROGRAMS

Doubled Haploids versus Conventional Breeding in CIMMYT Wheat Breeding Programs

Doubled haploid (DH) technology has been used in breeding programs for several decades and is currently the method of choice in a number of crop species, including barley (Hordeum vulgare L.), rapeseed (Brassica napus L.), maize (Zea mays L.), and wheat (Triticum aestivum L.). In this study we investigated via computer simulation the benefit of using DHs compared with the conventional wheat bre...

Welfare in horse breeding

Welfare problems related to the way horses are bred, whether by coitus or by the application of artificial reproduction techniques (ARTs), have been given no discrete consideration within the academic literature. This paper reviews the existing knowledge base about welfare issues in horse breeding and identifies areas in which data is lacking. We suggest that all methods of horse breeding are a...

Application of myostatin in sheep breeding programs: A review

Myostatin or growth and differentiation factor 8 (GDF8), has been known as the factor causing double muscling phenotypes in which a series of mutations make the myostatin protein inactive, hence disabling it to regulate the deposition of muscle fibre. This phenotype happens with high frequency in a breed of sheep known as the Texel. Quantitative trait loci (QTL) studies show that a portion of t...

Genotype X Region Interactions and Implications for Sugarcane Breeding Programs

AUSTRALIAN sugarcane breeding programs in the past have maintained fairly separate breeding and selection programs targeting different regions. This structuring implied an assumption that genotype x region interactions are important relative to genotype x environment interactions within regions, but this had not been tested. A research project was initiated in 1997 to help address this issue an...
