The establishment of PPP for Pre-breeding, development, present status and the way forward are described in this booklet. The success of the PPP is based on: • Pooled public funding • Participation from plant breeding companies • Engagement from research environments • 50/50-funding between public sources and industry The history of PPP for Pre-breeding has been a success and this booklet reveals some cases from the fruitful collaborations. The Nordic Council of Ministers is proud to have initiated the PPP for Pre-breeding and we are grateful to the partners, who have contributed to the process: plant breeding companies, universities, NordGen and governments of the Nordic countries, which have decided to continue funding the project. It is vitally important to continue this work because plant breeding is a long term process. There is no finishing line – only the way forward.

Abstract
Spring barley breeding has been carried out for almost a century in all three Baltic countries. The efforts of breeders have resulted in many new improved varieties released. The goal of our project was to survey the effect of these efforts throughout the century on this crop. The material included in this study consisted of 64 accessions originating from Latvia, Estonia and Lithuania, representing landraces, varieties released from 1927 to 2001, and breeding lines. Six agronomic traits (days to heading, days to maturing, plant height, harvest index, volumetric weight and thousand kernel weight) were recorded during two years (2002 and 2003) at three locations - Priekuïi (Latvia), Landskrona (Sweden) and Bjørke (Norway). The differences between spring barley materials of different origin and from different breeding periods were assessed, and variation of their performance in different environments was discussed
