the objective of this study was to investigate the effect of principal components (pc) of the regression coefficients (co)variance matrix on the lactation curve, and on the formation of selection index to modify the curve, based on these pc’s, and as well to estimate additive genetic and phenotypic variances and heritability of the constructed selection index. lactation period of 301 d (5-305) ...
Abstract Fast query processing is a primary goal of modern database systems. The use indexes crucial to reduce the execution times queries. Hence, it great interest determine an efficient selection for management system (DBMS). However, index problems are highly challenging as cause additional memory consumption and individual benefit influenced by others. In this paper, we consider accounting ...
The use of appropriate selection methods are important to increase yield in breeding programs. Utilization of selection indices is one of the most effective method for selection of superior genotypes to improve the complex traits such as seed yield. In order to evaluate the efficiency of different selection methods, 63 families of two F3 populations derived from inter-specific hybridization of ...
