Abstract

The invention belongs to the technical field of plant breeding, and discloses a crossbreeding method of high-oil-yield Chinese herbaceous peony in a desert areas. The crossbreeding method comprises the following steps of 1) selecting a female parent; 2) selecting a male parent; 3) reclaiming sand and improving soil; 4) performing transplanting and field planting; 5) adjusting the flowering phase;6) performing pollinating; and 7) performing harvesting. And 8) sowing in lines in a field. According to the crossbreeding method of high-oil-yield Chinese herbaceous peony in a desert areas, the current situation that the oil-used Chinese herbaceous peony cannot be planted in the desert is solved, the planting range of the oil-used Chinese herbaceous peony is enlarged, and the method is simple, easy to master, convenient to apply and popularize, short in breeding time, capable of bearing seeds in about 2 years, and high in yield after 3-5 years, and the using time can achieve 10 years or above. The propagation efficiency is high, large-scale production, seed production and harvesting are easy, and the raw material requirements of industrial and commercial production of the Chinese herbaceous peony oil are met.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for hybrid breeding of peony for high-yield oil in desert areas. Background technique [0002] Peony, also known as Jiangli, Licao, and Prime Minister of Flowers, is a perennial herbaceous flower belonging to the family Paeoniaceae. The tuberous root is produced from the bottom of the rhizome, fleshy, strong, spindle-shaped or long columnar, 0.6-3.5 cm thick. The petals of peony are obovate, and the disk is shallow cup-shaped. The flowering period is from May to June. It usually blooms alone at the top of the stem or in the axils near the top. The original flower is white, with 5 to 13 petals. The horticultural varieties are rich in flower colors, including white, pink, red, purple, yellow, green, black and multi-color, etc. The flower diameter is 10-30 cm, and the petals can reach hundreds of pieces. The fruit is spindle-shaped, and the seeds are round, oblong ...
