the susceptibility to terbacil of six randomly selected strawberry cultivars (‘aromas’, ‘chambly’, ‘harmonie’, ‘kent’, ‘la clé des champs’ and ‘seascape’) was analysed using chlorophyll florescence (cf) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. terbacil was applied at one of five rates...

Variability in breeding programmes for self-fertilised crops is created by crossing, and if the value of the crosses cannot be predicted in advance then this uncertainty means that a strategy of making many crosses is appropriate. However, since there is a limit to the capacity of a breeding programme, the more crosses that are made the smaller the size of each cross (F2 population size or numb...

BACKGROUND Susceptibility of sheep to scrapie infection is known to be modulated by the PrP genotype of the animal. In the Netherlands an ambitious scrapie control programme was started in 1998, based on genetic selection of animals for breeding. From 2002 onwards EU regulations required intensive active scrapie surveillance as well as certain control measures in affected flocks.Here we analyze...

BACKGROUND Following EU decision 2003/100/EC Member States have recently implemented sheep breeding programmes to reduce the prevalence of sheep with TSE susceptible prion genotypes. The present paper investigates the progress of the breeding programme in the Netherlands. The PrP genotype frequencies were monitored through time using two sets of random samples: one set covers the years 2005 to ...

Systematic coconut breeding has a long history in Sri Lanka. Diverse germplasm becomes the basis for breeding. Crop needs to change its directions with priority of industry. This review paper sheds glimpse into historical, conventional and modem exchange over last century from early 1900s 2019 their subsequent utilization National Coconut Breeding Programme is first attempt reviewing acquisitio...

Livestock, particularly small stock plays an important role to small-scale resource poor livestock keepers. Their efficient utilization on small land holdings result in enhanced farm family nutrition and increased farm productivity, hence focus on their development can be one way of reducing poverty among the poor. Past goat genetic improvement programmes in Kenya were based on government resea...

Instead of attempting a full scale review, this paper concentrates on the area of group breeding, firstly reviewing the essential differences between group breeding schemes and the traditional stud ram breeding system, then briefly reviewing the recentfine tuning of the open nucleus ram breem programme of the Australian Merino Society, and final1 +e identifying research and development prioriti...
