| The grain yield in cereals has increased considerable since the beginning of industrialisation of agriculture, including introduction of modern plant breeding 100-150 years ago. Since beginning of this period, plant breeding has selected and bred varieties suitable to the changing agricultural conditions, and hence to increasing extent focused on conventional high input agriculture as this type of agriculture developed. Most pronounced is probably the plant height, and old high plants are likely to lodge at the nitrogen level normally seen in modern industrial agriculture. Modern varieties are characterised by a high degree of specific resistance genes against selected pathogens on the expense on a broad durable polygenic resistance (Robinson 1995).... |

| It cannot be generally recommended to use older varieties unless quality aspect are reflected in the price, but some old varieties were compatible with the commonly grown modern varieties. The results calls for targeted breeding for low input conditions, as breeding for high input condition contribute little to the benefit of organic agriculture and other low input conditions. Research is needed to quantify the effect of the different yield components of breeding on grain and straw yield and quality at low input conditions. |
