Marker-assisted selection of dairy cows for β-casein gene A2 variant

Selection of Dairy Cows for Economic Merit

Selection of dairy cows for economie merit requires the use of a model for genetic merit that involves the cross-product of the genetic values for milk and milk fa t percentage. A linear and a quadratic index are described as procedures for selection of cows, the linear index being blp.~ + bzp, and the quadratic index being blp,~ + b~_pt + b~p,n 2 + b~p, ~ + b~p.,pt where p~ and pt are the phen...

SNP Marker Assisted Selection for Identification of Fusarium Resistant Melon Plants

Melon is an important crop cultivated in moderate climate regions of the world. One of the most important diseases of this plant is vascular wilt caused by Fusarium oxysporum f.sp. melonis (Fom). Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...

Molecular Marker Assisted Study of Kappa-casein Gene in Nili-ravi (buffalo) Breed of Pakistan

The present study was conducted to investigate the existence of polymorphism at Kappa-casein (κ-CN) locus in the Nili-Ravi buffalo. A PCR-RFLP method was used to distinguish buffalo κ-CN alleles. The genotypes were confirmed through specific, clearly distinguishable DNA band pattern resulting from digestion with three selected restriction enzymes (HinfI, HaeIII and MaeII). Analysis of 163 anima...

Selection theory for marker-assisted backcrossing.

Marker-assisted backcrossing is routinely applied in breeding programs for gene introgression. While selection theory is the most important tool for the design of breeding programs for improvement of quantitative characters, no general selection theory is available for marker-assisted backcrossing. In this treatise, we develop a theory for marker-assisted selection for the proportion of the gen...
