Variety traits
Lupinus angustifolius L.
Pod shattering in narrow-leafed lupin is a critical factor in yield loss caused by seed shedding during the ripening period. Resistance to this phenomenon is genetically determined and is essential to minimize losses during mechanized harvesting.
In the reference 16 varieties crop Narrow-leaf lupin, where this is mentioned in the description.
Spontaneous pod dehiscence leads to seed shedding while standing, with the risk increasing significantly during hot and dry weather. Susceptible varieties can lose over 90% of their yield if left standing too long, which is why breeding modern cultivars aims to reduce this rate.
The non-shattering trait is genetically controlled, particularly by the lentus and tardus genes, allowing the use of DNA markers for selecting resistant plants. Assessment of resistance is conducted by field-standing tests for 18–24 days after reaching full maturity, with a count of the percentage of opened pods.
Modern resistant cultivars demonstrate significantly lower loss rates. A shattering level within the range of 11–26% under conditions of prolonged field standing is considered an acceptable result, confirming the cultivar's suitability for harvest without a critical reduction in yield.
