Problems solved by technology

For ornamental plants with a longer growth cycle, such as woody ornamental plants (appreciation crabapple), due to their long growth cycle, they generally can enter the initial flowering period at the fastest about 3-4 years, and this traditional method has seriously hindered their growth. Process of flower color breeding

Embodiment

[0041]The present embodiment provides a kind of seedling stage prediction method of ornamental Begonia flower color, it comprises:

[0042] S1: Construct a quaternary data matrix to express the flower color of Begonia (W i x i Y i Z i );

[0043] The evaluation methods of suit types in different dimensions are as follows: ①W i Meaning: when the flower colors at the bud stage are purple, pink and white, assign W respectively i = 2, 1, 0;

[0044] ②X i Meaning: when the flower colors in the big bud stage are purple, pink and white, assign the value X i = 2, 1, 0;

[0045] ③Y i The meaning of : when the flower colors in the full flowering stage are purple, pink and white, respectively assign the value Y i = 2, 1, 0;

[0046] ④ Z i The meaning of : when the flower colors at the end flowering stage are purple, pink and white, respectively assign the value Z i =2,1,0.

[0047] S2: According to the importance of the quaternary variable, different bit weights are give...

Abstract

The invention discloses a seedling stage prediction method for ornamental Malus spectabilis flower color, and relates to the field of plant breeding. The seedling stage prediction method of the ornamental Malus spectabilis flower color comprises the steps that a color relation model of the flower color and the leaf color of ornamental Malus spectabilis is established; and the color of the ornamental Malus spectabilis is predicted in the seedling stage through the color relation model. According to the method, the significant correlation between the flower color and the leaf color can be effectively explored through the established flower color and leaf color relation model, prediction of the flower color of the ornamental Malus spectabilis in the seedling stage is achieved, and therefore the flower color breeding process can be remarkably shortened, and the breeding efficiency is improved.

Description

technical field [0001] The invention relates to the field of plant breeding, and in particular to a method for predicting the seedling stage of ornamental Begonia flower color. Background technique [0002] Flower color is one of the most important and intuitive ornamental traits of ornamental plants, and flower color breeding has always been an important direction of garden plant breeding. At the present stage, the flower color breeding methods of ornamental plants are mostly on the basis of hybrid breeding, carry out field observation and investigation, and screen out varieties with bright flower colors in the blooming stage for further cultivation. [0003] The breeding method based on the observation of flower color at the full flowering stage and the selection of individual plants with excellent flower color is intuitive and objective, and is very suitable for ornamental plants with a short growth cycle, such as herbs. For ornamental plants with a longer growth cycle, ...
