| A study was made of the changes from 1965 to 1997 in wheat varieties grown in selected shires representing farming systems across NSW. The eight shires examined were Wagga, Temora, Cowra, Carrathool, Lachlan, Coonabarabran, Gunnedah and Narrabri. In each shire, approximately 8-10 varieties were grown each year. Generally, three of those varieties were grown on a substantial proportion of the area; the minor varieties were either new varieties in the process of being built up to their peak adoption or older varieties in the stage of being replaced. In southern shires, there has been a tendency to reduce the number of varieties grown, while in the northern shires the number of varieties grown has increased since 1965. The progress of breeders in developing... |

| Feed grains researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, efforts to address the relative economic benefits from the different options for feed grains nutritional improvement are reported. The economic benefits arising from nutritional improvements in various feed grains are examined and compared to the benefits from increasing yields of the feed grains rather than improving their nutritional value. The results of the analysis of these options are presented in an economic surplus framework that enables the major beneficiaries and the relative gains for the... |
