Abstract
The Crang forest is in the suburbs of Buzau town, Romania, having an area of over 17 ha and being a remnant of the famous Codrii Vlasiei forest, known as the oldest forest in Romania.
BRGV Buzau specialists have carried out an evaluation of the genetic resources that compose the biodiversity of this area, especially a genotype of wild leek that has successfully preserved its purity and identity here and which is the subject of this study.
The genetic resource was genebanked in 2019 and was monitored and evaluated for 5 years.
Throughout the research, phenological, biometric, and laboratory observations and measurements were carried out.
It was found that the species ensures its perpetuation in three vegetative ways: through soil bulbs, soil microbulbs and aerial bulbs.
The greatest production potential is achieved by soil bulbs.
They produce vigorous plants for fresh consumption over a long period of time.
The weight of the mature bulb is, on average, 34.36 g.
The weight of microbulbs in the soil varies between 0.01 and 0.24 g.
The aerial bulb has an average weight between 0.01 and 0.4 g.
The number of microbulbs in the soil varies between 40 and 200 pieces.
The average number of aerial bulbs is 124 pieces.
Ex situ conservation works were undertaken by protecting and expanding the species in its natural environment, as well as in situ, the plant genetic material being preserved in medium and long-term controlled atmosphere cells in the BRGV Buzau laboratories.
It was found that in the intensive culture system, the production potential is significantly higher by more than 30% compared to its natural environment and it shows an increased genetic resistance to the pathogens that affect the species.
The species was introduced in intensive breeding works with the aim of obtaining new valuable commercial varieties.
