that control the weeping traits of peach trees.
The findings were published in BMC Plant Biology
.
Peach trees have a large annual growth and are prone to the formation of crown closure, and need to be pruned
a lot every year.
Excellent tree shape can promote fruit quality formation and save manpower and material resources
.
Weeping peach trees have a large opening angle, which is conducive to ventilation and light transmission inside the canopy, but at present, weeping peach trees are mostly found in ornamental peaches
.
The study of the mechanism of the formation of weeping traits of peach trees is conducive to the cultivation of new varieties that are both ornamental and edible, and lays a foundation
for the standardized and labor-saving cultivation management of peach trees.

The scientific research team used "97 dwarf" and "mandarin duck weeping branch" as the test materials, and clarified the genetic law
of peach tree weeping branch traits by constructing a hybrid population.
By using the mixed pool sequencing method of isolated population, the genes controlling the weeping traits of peach trees were located and finely located, and finally the target gene was narrowed to a physical distance of 150,000 base pairs, and a molecular marker
completely linked to the target trait was developed.
At the same time, the annual branches of ordinary and weeping peach trees were sliced and observed, and obvious differences in secondary xylem were found, which laid a foundation
for further study of the regulation mechanism of weeping traits of peach trees.
