Problems solved by technology

The climate in northern my country is dry and has four distinct seasons. It is very hot in summer and extremely cold in winter. Because Cymbidium prefers a warm, humid and semi-shady environment, it will not grow normally, have less flowering, and a short flowering period when planted in the north. Phenomenon, can not meet the needs of the majority of northern flower lovers

Embodiment 1

[0042] (1), screen the provenance and select the parents according to the dry and heat-resistant standard

[0043] Collect the provenance, screen the collected provenance according to the dry and heat resistance standard, and select the parents. The selected parents are: beloved Cym.Ly510 Enzan Moon'Ai Nair' and new moon Cym.Lovely moon crescent.

[0044] Anti-drying: It refers to anti-air drying, that is, when the relative air humidity is not higher than 20%, the normal growth duration is not less than 45 days.

[0045] Heat resistance: mainly refers to the ability to resist high temperature in summer, that is, when the temperature is 35°C, the normal growth duration is not less than 45 days (intermittent treatment); when the temperature is higher than 35°C but not more than 41°C (intermittent treatment), the normal growth duration is not less than 45 days.

[0046] In addition, five pairs of traits should be considered, namely, flower color, flower size, plant height, leaf...

Abstract

The invention relates to a seed selection method for drought and heat resistant cymbidium hybridum. The method comprises the following steps: (1) carrying out the screening and parent selection on seed sources according to the standard of drought and heat resistance; (2) hybridizing the parents which have the drought and heat resistant characteristic and are selected in the step (1); (3) carrying out the seed asepsis culture; (4) carrying out the filial generation culture; and (5) carrying out the breed screening of the filial generation according to the standard of drought and heat resistance so as to complete the seed selection. The seed selection method for drought and heat resistant cymbidium hybridum can make full use of cymbidium hybridum resources at both home and abroad to culture a new cymbidium hybridum species with the proprietary intellectual property rights. The new cymbidium hybridum has the advantages of draught resistance, high temperature resistance, and adaptation to be implanted in North China.

Description

technical field [0001] The invention relates to the technical field of flower breeding, in particular to a method for breeding Cymbidium cymbidium with resistance to dryness and heat. Background technique [0002] Cymbidium is a large-flowered epiphytic species in Orchidaceae, which is usually hybridized from large-flowered original species. Cymbidium is deeply loved by flower lovers because of its many flowers, bright color and tall plants. At present, the research on Cymbidium in our country mainly stays in the cultivation technology, flower forcing technology and rapid propagation technology, but there is still a lack of in-depth research on the cultivation technology of new varieties of Cymbidium. Cymbidium is native to the southwest of my country. It likes warm winters and cool summers. It likes high humidity and strong light. The optimum temperature for growth is 10°C to 25°C. The nighttime temperature is about 10°C. Especially during the flowering period, keeping th...
