Report 1988

Autor: Nienhuis, James Singh, Shree P.

Genetic variance, heritability, and expected response from selection are useful in devising alternative methods and criteria of selection. The objectives of this study were to estimate these for seed yield and its components from 200 F2 populations involving 80 cultivars and lines of mostly small...

Cultivars and landraces of a crop species represent the primary gene pool available to plant breeders for improvement of crop plants. Knowledge of relative genetic relationships among genotypes is useful in a breeding program because it permits organization of germplasm resources. The genetic rel...

Cultivares y variedades criollas de una especie cultivada, representan la principal fuente de genes disponibles para el mejoramiento de cultivos. El conocimiento de la relación genética entre genotipos es útil en un programa de mejoramiento genético porque permite la organización del germoplasma ...

More than 60% of common bean production worldwide is derived from cultivars of Middle American origin. Understanding the diversity of these will facilitate their use in genetic improvement. The objective of this study was to analyze a collection of 269 landraces of common bean (Phaseolus vulgaris...
