Oilseed rape (Brassica napus) is one of the most important oil plants worldwide. In addition to the production of cooking oil, it also provides animal feed and sustainable raw materials for industry. To increase yields, reduce the consumption of resources and improve resilience to climate change, the breeding of new oilseed rape varieties plays a crucial role. This is where phenotypic measurements come into play. But what exactly does that mean, and why is it so important?
What are phenotypes?
The phenotype encompasses the observable characteristics of an organism, which are influenced by the interaction between the genotype (genetic information) and the environment. In the case of rapeseed, this can include characteristics such as size (directly related to oil content) or color.
Why are phenotype measurements important?
Breeding better varieties:
Modern plant breeding relies on accurate measurements of phenotypes to select promising plants. Traits such as improved drought tolerance or higher oil content are evaluated to develop varieties that produce higher yields while being more environmentally friendly.
Combining genomic and phenotypic data:
Genomic selection uses genetic markers to predict the best breeding lines. However, without precise phenotypic data, this method is inefficient. Combining genotype and phenotype data enables breeders to make more accurate predictions and speed up the breeding process.
Adaptation to climate change:
The variability of climate conditions is a major challenge. Phenotypic data helps to identify plants that can grow better under extreme conditions, such as drought or flooding.
The MARViN ProLine II offers excellent possibilities to measure the phenotypes of rapeseed very efficiently and precisely. Further information about the device can be found here.
