Embodiment 1

[0009] Hybridization method: compound hybridization method. First, the hybrid offspring is obtained by crossing Yunnan Michelia as the female parent and Nanya Michelia as the male parent; after the hybrid offspring blooms, the hybrid offspring is used as the female parent and Shenshan Michelle as the male parent to obtain a new variety "Yunrui".

[0010] In 1997 with Yunnan smile ( Michelia yunnanensis ) is the female parent, South Asian Michelle ( M. doltsopa ) to obtain hybrid offspring by crossing the male parent. In 2004, the offspring of this hybrid was used as the female parent, and the Mishan Smile ( Michelia maudiae ) to the male parent to obtain a new variety "Yunrui". In 1997, half-bloomed flowers were collected in the full flowering stage of Miracle in South Asia, the stamens were removed, the anthers were allowed to split naturally at room temperature, pollen was released, collected, and dried and stored; when the flowers of Miracle in Yunnan were not fully op...

Abstract

The invention discloses a method for breeding michelia variety Yunrui. The method comprises the following steps of: hybridizing michelia yunnanensis serving as a female parent and michelia doltsopa serving as a male parent to obtain a filial generation; and after the filial generation flowers, hybridizing the filial generation serving as a female parent and michelia maudiae serving as a male parent to obtain the michelia variety Yunrui. The new variety 'Yunrui' integrates partial excellent traits of three parents: the shrub is branched, dense and glabrous throughout. The leaves are leathery and oblong to inversely oval long circle, the length is 16 to 18 centimeters, the width is 6 to 8 centimeters, the tip is acute, and the base is narrow and wedge-shaped; the leaves are deep green and glossy; and the petiole nearly has no stipule scars. The flowers are milky white and fragrant; the number of tepals is 9 to 10, the tepals are inversely oval, the length is 6 to 7 centimeters, the width is 3 to 4 centimeters, the base is light yellow, and the tip is short and small; the carpel is green, the style is purple red, the androeceum is light yellow, and the stamen of the base is petalled; and the flowers are expanded and broadly campanulate.

Description

Technical field: [0001] The invention belongs to the field of biotechnology, and relates to a method for cultivating plant hybrids, in particular to a hybrid offspring obtained by crossing Yunnan Michelia as the female parent and Nanya Michelia as the male parent, and a new variety "" "Yunrui" cultivation method. Background technique: [0002] The method and technology of cultivating new varieties by cross-breeding with the hybrid progeny of Michelia as the female parent and Shenshan Michelle as the male parent have not been reported yet. Invention content: [0003] The object of the present invention is to provide a method for cross breeding with the hybrid progeny of Michelia plants as the female parent and Michelia Michelia as the male parent. [0004] Above-mentioned purpose of the present invention is achieved by following technical scheme: [0005] The breeding method of the new Michelia variety "Yunrui" is based on Yunnan Michelia (Yunrui) Michelia yunnanensis ) ...
