Supplementing the studbook. Using genetic analysis to complement a captive breeding programme of an endangered primate, Hylobates moloch.
Genetic analysis of animals involved in captive breeding and reintroduction programmes can provide valuable information to aid in maintaining wild type genotypes and genetic variability. Hylobates moloch, also referred to as the silvery gibbon, is an Endangered primate species endemic to the …

The effects of novel genetic diversity on yield and yield traits in a hybrid wheat pre-breeding programme
Hybrid breeding, where two inbred lines are crossed to create superior F1 plants, has the potential to increase yield and yield stability in wheat. However, commercialisation of hybrid wheat is limited by high production costs but could be offset by increasing the yield. Introducing new diversity …

Inter-specific hybridization in the fish family Cyprinidae
… was investigated through:an experimental breeding programme to investigate the nature of inter-species and hybrid gamete compatibilities;the identification of species and hybrids from the experimental breeding programme through the analysis of morphometric, meristic and genetic characters …

Genetic control and prediction of milling and baking quality for UK wheat breeding
… baking quality in collaboration with the DSV UK breeding programme. A wheat multi-parent advanced generation intercross population was used to investigate the genetic control of multiple wheat quality and micronutrient traits. This analysis identified multiple quantitative trait loci (QTL) with …

The characterisation of semen from Zulu Rams raised under extensive management conditions in KwaZulu-Natal
… for the strategic planning of conservation programmes. The study was designed to evaluate some of the factors viz. ram age, season and geographic location, that influence reproductive performance in Zulu sheep populations based on the viability of Zulu ram semen. Spermiogramic parameters …

The reintroduction of bearded vultures in South Africa: a feasibility analysis
… Various release strategies ranging from captive breeding prioritization to release prioritization were modelled using stochastic modelling software. Results indicated that straight releases, without any captive breeding support, had a high probability of failure (defined <34 individuals) ranging …

Comparative analysis of wild and long term captive bred Partula snails using morphometrics and population data
… been collected since 1962 to start a captive breeding programme coordinated by the Zoological Society of London (ZSL). Over 15 species are kept in captivity currently. Several reintroductions have taken place with over 10,000 snails being reintroduced to the islands with varying levels of …

Propagation of asparagus (Asparagus officinalis L.) via somatic embryogenesis
… or as the parents of new hybrid cultivars in breeding programme were used. Among the 20 asparagus genotypes tested, ASC 26, ASC 69 and CRD 168 were all highly amenable to cell culture as indicated by high callus initiation growth in both dark and light conditions. Some genotypes did not form …

SSR-based genetic mapping of QTLs determining chilling requirements for time of initial vegetative budbreak in domesticated apple (Malus x domestica Borkh.) cultivar ‘Anna’ x ‘Austin’
… on related mapping populations in the apple breeding programme, and for the future identification of candidate genes controlling the process of budbreak.

A study of bovine salivary proteins
… in bovine saliva. This study paralleled the breeding programme selecting animals for high (HS) and low (LS) susceptibility to bloat. Two groups of adult cows, classified as HS or LS by field gradings (Group 1 and Group 2), and three groups of HS and LS progeny (1973, 1974 and 1975 animals), …

The impact of genetic variation on functional, technological and digestive properties of β-lactoglobulin
… genetic variants as part of the national breeding programme, resulting in a diverse pool of variants among Irish cows. Initially, to support understanding of the distribution of genetic variants within an Irish herd, the protein profiles of 48 cows was assessed; of these cows, 17 genetic …
