Problems solved by technology

The existing varieties in the world are mainly cultivated by the Netherlands, New Zealand, the United States, Japan and other countries. The breeding of calla lilies in my country has just started. The varieties used for production are all foreign varieties, and most of them were introduced 10 years ago. There are old and degraded varieties. Serious and a series of problems such as the difficulty of exporting cut flowers, the current situation of calla lily breeding does not match the needs of the rapid development of the industry
Some people are trying to breed calla lilies, but so far there have been no research reports on hybrid breeding. It is imminent to establish hybrid breeding technology and cultivate new varieties

Embodiment 1

[0021] A. The colored calla lily varieties "Kaman" and "Black Forest" were used as female and male parents respectively, and 4cm bulbs were selected for planting in March;

[0022] B. When the colored calla lily female plant in step A grows until the spathe has just unfolded and the stamens have not released pollen, cut off the entire male flower on the upper part of the anthurium, and if there are male flowers in the lower part of the incision, use tweezers to carefully remove the male flower, and wait for the stigma of the female flower to secrete When going out the mucus, collect the pollen that the male flower spits out on the same day from the male plant of step A, and carry out artificial pollination to the stigma of the female flower;

[0023] C. Cut the spathe of the pollinated plant in step B until only 3 cm of the base is left to expose the female flowers to prevent mildew, then bag the female flowers for 6 days, remove the bagging, and continue to grow until the p...

Embodiment 2

[0030] A. The colored calla lily varieties "Hayman" and "Faith" were used as female and male parents respectively, and 5cm bulbs were selected for planting in March;

[0031] B. When the colored calla lily female plant in step A grows until the spathe has just unfolded and the stamens have not released pollen, cut off the entire male flower on the upper part of the anthurium in time, and carefully remove the male flower remaining in the lower part of the cut with tweezers until the stigma of the female flower is secreted When going out the mucus, collect the pollen that the male flower spits out on the same day from the male plant of step A, and carry out artificial pollination to the stigma of the female flower;

[0032] C. Cut the spathe of the pollinated plant in step B until only 2 cm of the base is left to expose the female flower to prevent mildew and rot, then bag the female flower for 7 days, remove the bag, and continue to grow until the plant of the plant withers a...

Embodiment 3

[0039] A. The colored calla lily varieties "Aries" and "Heimajie" were used as the female parent and the male parent respectively, and the bulbs of 4cm were selected and planted in March;

[0040] B. When the colored calla lily female plant in step A grows until the spathe has just unfolded and the stamens have not released pollen, cut off the entire male flower on the upper part of the anthurium in time, and carefully remove the male flower remaining in the lower part of the cut with tweezers until the stigma of the female flower is secreted When going out the mucus, collect the pollen that the male flower spits out on the same day from the male plant of step A, and carry out artificial pollination to the stigma of the female flower;

[0041] C. Turn back the whole spathe of the pollinated plant in step B to expose the female flowers to prevent mildew, then bag the female flowers for 5 days, remove the bagging, and continue to grow until the plants of the plants wither and ...

Abstract

The invention provides a method of breeding a novel cultivar of zantedeschia hybrida by artificial supplementary pollination, which comprises castration of a female parent, supplementary pollination, processing and bagging of spathes, germinating of seeds, quick bulbing of offspring, screening of excellent individuals, breeding of the excellent individuals and the like. Especially, degradation and unclear source of hybrid offspring caused by selfing and hybridization with a non-selected male parent can be avoided by timely castration and female flower bagging techniques, efficiency of hybrid breeding is improved, and true hybrid can be obtained. Seed bulbs are reserved in the field to overwinter naturally, so that digging and planting procedures are reduced, bulbing cost is reduced, and seed breeding cycle is shortened. The method can reduce mildew and rotting rate of fruits, increase maturing rate and germination rate, shorten offspring bulb breeding time, improve efficiency of hybrid seed breeding and tree hybrid obtaining, and shorten the seed breeding cycle.

Description

technical field [0001] The invention relates to a method for cultivating new varieties of colored calla lily by artificial assisted pollination, and belongs to the technical field of new variety breeding. Background technique [0002] Colorful calla lily is araceae (Araceae) Calla Lily (Zantdeschia) Calla lily (Zantdeschia aethiopica) Other 6 species and their hybrids (Z. hybrida) the general term for. Colored calla lily is known as "colored lily" and "21st century flower star" due to its unique flower shape, elegant shape and bright colors. It is one of the bulbous flowers with the most development potential in the world. [0003] Research on calla lilies in my country began in the 1990s, and the research content focused on introduction and screening, tissue culture and rapid propagation, bulb breeding and storage, flowering regulation, and potted flower production. There is very little work on breeding technology and new varieties, and only research reports on ploi...
