Variance components, heritability estimates, and breeding values for performance test traits in Old Kladruber horses
The Old Kladruber horse is an important Czech genetic resource. In the current study, two categories of traits were evaluated – the first, a numerical score for Type and Gender Expression and the second, 11 traits describing performance divided into four categories: (1) Rideability (Overall Impression, Rideability), (2) Gaits (Walk, Trot, Canter), (3) Carriage Drivability (Dressage Test, Obstac...
متن کاملinvestigation of genetic diversity and broad sense heritability in watermelon accessions of sistan
to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...
متن کاملEstimating the Broad-Sense Heritability of Early Growth of Cowpea
Cowpea is an important tropical crop. It provides a large proportion of the food resource for the African human population and their livestock. The yield and quality of cowpea have been dramatically improved through traditional breeding strategies for the past few decades. However, reports of heritability estimates for early growth of cowpea are rare. We designed a simple experiment to estimate...
متن کاملEffect of Regulatory Architecture on Broad versus Narrow Sense Heritability
Additive genetic variance (VA ) and total genetic variance (VG ) are core concepts in biomedical, evolutionary and production-biology genetics. What determines the large variation in reported VA /VG ratios from line-cross experiments is not well understood. Here we report how the VA /VG ratio, and thus the ratio between narrow and broad sense heritability (h(2) /H(2) ), varies as a function of ...
متن کاملتجزیه ژنتیکی برخی صفات مورفولوژیک در گندم از طریق تجزیه میانگین نسل‌ها در شرایط تنش و عدم تنش رطوبتی
Study of heritability, types of genes action and determination of effective breeding strategy to improve physiological and morphological traits especially under drought stress conditions are very important. For such purpose, an experiment was carried out using the generations of the crosses between two pure lines (Kavir × Roshan) under drought stress and non-stress conditions based on randomiz...
