Field trials shows minor effect of modern plant breeding on grain yield of spring wheat at organic agriculture conditions
Provedor de dados: 21
Autores: Borgen, Anders; Grupe, Per.
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.

Yield performance in heritage spring wheat and barley varieties in organic farming
Provedor de dados: 21
Autores: Borgen, Anders; Grupe, Per; Ytting, Nanna Karkov.
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)....

Maintenance breeding of conservation cereal varieties
Provedor de dados: 21
Autores: Borgen, Anders; Grupe, Per; Larsson, Hans.
The experiments shows that within the heritage material, varieties are identified with unique quality traits, including taste, colour and backing quality, which are not found in high yielding modern varieties available for organic farming. The paper presents the second year result of field evaluation of 212 Scandinavian heritage varieties grown on two sites in Denmark in 2007.

Yield performance in heritage spring wheat and barley varieties in organic farming
Provedor de dados: 21
Autores: Borgen, Anders; Grupe, Per; Karlov, Nanna.
Field trials show that under organic conditions, heritage spring cereals can in some cases give a yield and quality compared with modern varieties. The paper discuss the season for the lack of yield improvement under organic conditions due to plant breeding.
