of performance is needed to define a breeding goal and develop a sustainable breeding programme for improvement.'
In 1st group 108 birds of higher body weight were selected with full pedigree record
to compare with the birds selected with mass selection and random-bred control; in 2nd group 324 birds of higher body weight were selected to be the parent of next generation.
This luxurious volume is the first time that a photographic and pedigree record
of the winners of all four sections of the Welsh breed have been brought together.
Out of 22 groups, first group was maintained with fully pedigree record
, in second group birds were picked randomly without following any selection procedure, rest 20 groups were subjected to mass selection.
A recent RFLP-based survey of 55 landraces from Afganistan, Iran, and Turkey, which were unrelated by pedigree, detected high levels of genetic similarity (mean = 0.91) among accessions (Kim and Ward, 1997), suggesting that low levels of allelic variation existed in the wheat genome prior to initial improvement efforts through breeding and accurate pedigree record
from a total of 2985 animals during 1999-2013 were analysed.
It is the only project In the country where a huge population of animals is available with accurate production and pedigree records
of each and every animal over generations, with well-established progeny testing network in 37 Military Farms to cover all the agro-climatic zones of the country.
Weekly milk yield and pedigree records
of Sahiwal cows calved between 1984 and 2005 were collected from the milk record, disposal and birth registers.
As mentioned Koening and Simianer (2006), inbreeding can be evaluated on the basis of the pedigree records
, where the inbreeding coefficient is defined as the probability that the two alleles of an individual are identical by descent.
In breeding coefficients were estimated through using a total of 7345 pedigree records
of Sahiwal cattle maintained at 6 institutional herds viz.
Three of the Texel shearlings on offer were used as lambs last season and are all in the top 20 of over 600 pedigree recorded
Texel rams independently evaluated by Signet.
Help with pedigree records
came from the Welsh Pony & Cob Society (though Dr Davies notes the official records weren't always accurate).
