Problems solved by technology

[0004] Due to the different flowering habits of the white crane under natural conditions, the male and female flowers are not open at the same time, the natural pollination rate is low, resulting in low seed setting rate, low seed germination rate, and poor uniformity of seedlings.

Embodiment Construction

[0028] A kind of artificial breeding method of white crane taro of the present invention, comprises the following steps:

[0029] 1. Parent source and selection

[0030] Combination: ♀Jesus 2# (Spathiphyllum "Chris2#")×♂Starlight White Palm (Spathiphyllum "Starlite").

[0031] Among them, Jesus 2# (Spathiphyllum "Chris2#", code SPAT12) is quoted from the northern part of the United States. It is a small and medium-sized potted plant with a plant height of 25.0-30.0cm. The leaves are dark green, broadly elliptical, acuminate, and the leaf margins are wavy. shape, leaf surface shrinkage is obvious, leaf length 17.5cm, width 8.5cm, pedicel length 35.0cm, flower bracts white, oval-lanceolate, length 11.0cm, width 5.6cm, spadix length 3.4cm, on average 4-5 flowers;

[0032] Starlight white palm (Spathiphyllum "Starlite", code SPAT14) was introduced from the United States. It is a small potted plant with a plant height of about 15cm, leaves narrowly lanceolate, 18cm long, 3.5cm wi...

Abstract

The invention relates to a method for artificially breeding spathiphyllum. The method comprises the following steps of: hybridizing Jesus No.2 and spathiphyllum starlight which are used as parents to obtain seeds in a generation F1; sowing the seeds in the generation F1; comparing and eliminating the produced seedlings in the whole growth process, screening excellent individual plants suitable for market prospect, wherein the individual plant has hybridizing advantages of the parents; carrying out tissue culture rapid clonal propagation on the selected excellent individual plants, finally obtaining seedlings with consistent characteristics, and carrying out batch trial planting to obtain a variety with characteristics consistent with these of the optimized individual plants, same with these of the optimized mother plant of the generation F1, thus the selected variety is confirmed to form a new variety, and consistence and stability of all plant lines are ensured through the vegetativepropagation of the individual plant.

Description

technical field [0001] The invention relates to an artificial breeding method in the technical field of plant hybrids, in particular to an artificial breeding method for white crane lily. Background technique [0002] White crane lily, also known as white palm, is a plant of the genus Spathiphyllum in the family Araceae, native to South America. White crane lilies have delicate leaves and white spathes. They are important potted plants for viewing flowers and leaves, and are also suitable for indoor and outdoor landscape greening, especially hydroponics. my country began to introduce species in the late 1980s, and developed rapidly throughout the country in the late 1990s. [0003] The source of the new variety of white crane taro is firstly the natural mutant strain, whose disadvantage is that it is unstable, and the probability of obtaining it is only a few ten thousandths, and it is difficult to produce it industrially; the second is modern breeding technology, especiall...
