Abstract :

Los programas de selección en la especie canina deben por un lado garantizar un progreso adecuado y por otro lado asegurar una correcta gestión genética de las razas. Los objetivos de selección en esta especie deben emanar de su especialización funcional y su traslado a los criterios de selección debe hacerse por su estrecha correspondencia con dichos objetivos y su facilidad de registro. Los ...

Abstract :

[Kouiku 55] is an extremely early, goodeating quality, high yielding line of glutinous paddy rice which was brought up in the Agricultural Research Center of Kochi Prefecture. It was brought up from anther culture of the first filial generation (F1) of [Kouiku 27/H3A3 70], and was recognized as an extremely early promising line which has apparently early maturity in comparison with "Natsuhikar ...

Abstract :

[Kouikusake 54] is a new rice line appropriate for sake brewing been obtained by mating "Yamadanisiki" having the best qualities for sake brewing, with "Hinohikari" as the showing a good taste, and grown through the anther culture of the first filial generation (F1) in 1990. We have carried out performance tests and fields tests on this variety as [Kouikusake 223] in 1994 and [Kouikusake 54] s ...

Abstract :

A proportion-defined trait is sometimes of interest to animal and plant breeders. We consider the linear index selection exactly representing individual truncation selection based on the phenotypic value of a proportion trait. It is assumed that proportion component traits are normally-distributed. Using the linear index, we give an expression for the phenotypic selection differentials of the ...

Abstract :

Optimum number of cycles and rate of selection and optimum population size to give the highest cost efficiency in mass selection for allogamous crop plants were investigated. The optimum values of these variables were obtained based on the numerical calculations of a new selection efficiency index, S/C, where S stands for the probability that the desired genetic improvement is achieved in the ...

Abstract :

In order to congregate the desirable genes in local onion population of Gholy- Ghesseh, mass selection method was used in this study carried out from 1998-2002 in Kheir-Abad Agricultural Research Center, Zanjan, Iran. In 1998, based on bulb characters , single bulbs were selected and in the next year , planting was conducted in isolated plots providing open pollination. Seeds of selected plant ...

Abstract :

Creation of new genetic complexes and selection the bests among them is one of the important stages in plant breeding. In order to evaluation and selection in segregating population of durum wheat lines for agronomic traits that influence grain yield, this study carried out on 93 numbers of F4 segregating populations during 2004-2005 cropping season in Maragheh dryland agricultural research st ...

Abstract :

El objetivo final de cualquier programa de mejora debe ser mejorar la competitividad y rentabilidad de las explotaciones de vacuno de leche. En la actualidad los caracteres que se incluyen dentro de los objetivos de selección están directamente relacionados con la rentabilidad de la explotación y enfocados a mejorar tanto la calidad como la cantidad de la leche. En este articulo se describen l ...
