480 PB 408 HORTICULTURAL GERMPLASM MAINTAINED AT THE WESTERN REGIONAL PLANT INTRODUCTION STATION

Conservation of Grass Collections at the Western Regional Plant Introduction Station

Germplasm managers at the Western Regional Plant Introduction Station (WRPIS) have focused on improving seed regeneration in forage and turf grass species through studies of diversity maintenance, using isozyme markers in annual ryegrass (Lolium multiflorum Lam.) and through studies of pollen isolation, using strains of dominant pubescent and recessive glabrous smooth bromegrass (Bromus inermis...

Genetic Markers and Horticultural Germplasm Management

This paper is adapted from the text of a seminar of the same title presented as part of the Workshop on Sustainability of Vegetable Breeders’ Genetic Resources, 26 July 1993, at the 90th Annual Meeting of the American Society for Horticultural Science. It represents the distillation of a more extensive treatment of genetic markers and germplasm management (Bretting and Widrlechner, 1995). Disci...

Horticultural Plant Breeding: Past Accomplishments, Future Directions

Genetic improvement of agronomic crops through breeding, which typically are marketed as commodities, are grower directed. Breeding objectives principally involve increasing yield, often based on resistance to biotic and non-biotic stress. For example improvement in hybrid maize yields have relied on increasing yield stability under high populations. In horticultural crops, breeding objectives ...

Atmospheric Transport to the Gaw Regional Station

A study on the connection between the state of the atmosphere, as represented by cluster-mean trajectories, and the chemical composition of precipitation at the Croatian GAW regional station of Zail,art is presented. The trajectory cluster analysis has been done on the basis ofdaily backward trajectories calculated for 1996, using the IIYSPLIT_4 trajectory model. The seasonal cluster analysis i...
