Its resistance to Alternaria and Peronosporosis is average, at the level of the standard. Its resistance to Fusarium is high, 2-2.5 times higher than Hannah variety’s. The variety is moderately damaged by cruciferous flea beetles and blossom beetles.
Competitiveness. Due to its high productivity and high quality of the seeds “Madrigal” variety is quite competitive in the Central, Volga-Vyatka, and East Siberian regions, where the variety is introduced in the State Register and approved for production.
Main advantages. This variety provides high yield, produces high quality oil and meal, it is also resistant to major diseases, technologically oriented for mechanical harvesting. It is recommended for cultivation for seeds and animal feed purposes.
In the field tests conducted by FSBI ARIR the variety yield was 2.59 t / ha , it exceeded the standard variety indices as Hannah variety by 0.52 t / ha or 25.1%, for the oil yield the index was higher by (1.09 t / ha) - 0,21t / ha.
Variety type "00".The fat content in the seeds is 43,7-45,1% , the content of erucic acid in the oil is 0.1-0.3% , the content of glucosinolates in the meal is 0.2-0.5% (4,7-11,7 umol / g), the content of the protein in seeds is 18,3-20,1%. The green mass contains 18.1% protein.
The commercial value of “Madrigal” variety is its high yield, its resistance to various biotic stressors, high quality of oil and meal and its technology of cultivation.
