Genetic progress in Dutch crop yields

The variation of agronomic traits associated with breeding progress in winter barley cultivars

“…3D). Similar results of genetic improvement per year of release in barley were previously reported by Rijk et al (2013) for conditions of the Netherland and Laidig et al (2014) for Germany. Also, a positive trend of grain yield increase was found for wheat in Serbia (Mladenov et al, 2011) and other small grain crops worldwide (Araus et al, 2008).…”

Crop yields and NPK use efficiency of a long-term experiment on a former sea bottom in the Netherlands

“…Our results largely agree with those of a recent study on genetic progress in yields of sugar-beets, potatoes, and spring-barley in the Netherlands (Rijk et al, 2013 , being the same as the 120 kg ( Figure 2.7, top) found in our experiment. The increase in dry-matter yields of ware potatoes found in variety trials was 30 kg ha -1 y -1 (Rijk et al, 2013), so lower than the increase of 64 kg ha -1 y -1 shown in Figure 2.7. In both studies, however, the very large yield variability among years weakens any statement on yield increase of potatoes.…”

Development and application of a 20K SNP array in potato

“…Particularly sugar beet displays an exponential increase in crop production over the last decade. The limited genetic gain for yield in potato as reported in Rijk et al (2013) are supported by data collected within the research of D'hoop (2009) (Fig. 2a).…”

“…1. The genetic gain of several crops has been estimated (Higashide and Heuvelink 2009;Rijk et al 2013;Laidig et al 2014). For example Higashide and Heuvelink (2009) show that for tomato an average of 0.9% genetic gain for yield is established in the last 30 years.…”

“…The study of Laidig et al (2014) compares the yields of varieties released in the last three decades of 12 crops (potato not included) in Germany, showing genetic gain for the majority of these crops. In contrast to Laidig et al (2014) the study of Rijk et al (2013) included potato and performed a similar study for Dutch varieties and showed a limited increase of potato yield as compared to the increase of yield for wheat, barley and sugar beet. Particularly sugar beet displays an exponential increase in crop production over the last decade.…”
