Su Xiuxuan's team built a molecular fingerprint map library for the main varieties of lavender in Xinjiang.

On May 8th, a source from the university said that Su Xiuxuan's team had built a molecular fingerprint map of the main varieties of lavender in Xinjiang for four years.
use the molecular fingerprint map library to verify and distinguish lavender seed types through "parental identification" and quickly and accurately identify excellent genes in seed resources.
Lavender is a valuable natural fragrance known as the "Aromatic Queen".
Yili region and the world famous lavender region of Provence, France, Hokkaido, Japan belongs to the same latitude zone.
first introduced lavender from France in 1964 and has become one of the world's three largest lavender planting bases.
however, most of Xinjiang lavender for the introduction of cultivated species, some of the introduction of species after long-term natural hybridization and genetic mutation, formed a large number of new characteristics of the strains, in the planting area in the cause of the introduction of species, hybrids and mutant species common cultivation phenomenon.
the mixed cultivation of this kind of good and inferior varieties, the genetic background of interspecies kinship is not clear, not only affects the increase of lavender yield, but also restricts the innovation and selection of fine varieties, restricts the formation and development of lavender industry.
and the existing morphological marker identification synline method is difficult to accurately distinguish the lavender seed type.
to this end, the team from the lavender morphology level, cytology level and essential oil physical and chemical aspects of the seed resources of Xinjiang lavender systematic analysis and set up the corresponding seed resources morphology, cytology, physical and chemical marker database, screening out the high-quality oil content of excellent and excellent seed quality, improve the lavender seed resources identification efficiency and accuracy. At the same
time, using ISSR molecular marker technology to study genetic diversity of lavender seed resources, a molecular fingerprint map of lavender main plant varieties in Xinjiang was constructed, and the genetic diversity differences and kinship between different lavender varieties were determined according to the genetic characteristics of DNA.
Su Xiuxuan revealed that the team will also be based on the molecular fingerprint map library will be screened out of high-quality heterogeneous hybridization, to achieve the polymerization of excellent traits, the creation of high-yield, high-quality, multi-purpose new lavender line.
