Variety traits
Oil content is the percentage of crude fat and fat-like substances in seeds or fruits, which determines the oil yield from the raw material. This parameter is a key indicator of crop quality and the economic efficiency of a variety.
Mentioned in descriptions 7 813 varieties reference book.
Oil content represents the percentage of crude fat in seeds, which directly influences the economic efficiency of processing. The expression of this trait is manifested in the volume of oil obtained from each ton of raw material and is evaluated using laboratory methods such as Soxhlet extraction, nuclear magnetic resonance, or infrared spectroscopy.
The value of this parameter depends on the genetic potential of the variety established by breeders, as well as on external conditions during the growing period. Favorable temperature regimes during flowering and grain filling promote fat accumulation, while extreme heat or excess precipitation can reduce the final result.
The stability and level of oil accumulation are closely related to agronomic factors, including the balance of mineral nutrition with an emphasis on phosphorus and potassium. Proper sowing density and timely harvesting allow for the maximum realization of the variety's potential, whereas an excess of nitrogen, the presence of weed impurities, or mechanical damage to seeds lead to a decrease in oil content.
Selection based on the description text, not official resistance ratings: such data is not available in registers. Mention indicates that the trait is discussed in the variety's sources; see the variety's profile for details on what is specifically stated.
