Embodiment 1

[0019] 1) The disease-resistant semi-dwarf non-photosensitive medium-growing green-leaf rice variety Wunong No. 1 was selected as the recurrent parent R, and the purple-leaf rice variety IR1552(A), the yellow-leaf rice variety Huangyu B(B), and the rice striped flower were selected. The leaf mutant st(t)(C) and the yellow-green leaf rice variety ygl10(D) are the parents for the introduction of leaf color traits, and crosses R / A, R / B, R / C, and R / D to obtain hybrid F 1 Substituted by F 1 - A , F 1 - B , F 1 - C , F 1 - D express;

[0020] 2) planting F 1 - A , F 1 - B , F 1 - C , F 1 - D , backcross with the recurrent parent R at the flowering stage to obtain the backcross F1 generation, respectively with BC 1 f 1 - A 、BC 1 f 1 - B 、BC 1 f 1 - C 、BC 1 f 1 - D express;

[0021] 3) Plant BC 1 f 1 - A 、BC 1 f 1 - B 、BC 1 f 1 - C 、BC 1 f 1 - D , respectively harvested to get BC 1 f 2 - A 、BC 1 f 2 - B 、BC 1 f 2 - C 、BC 1 f 2 - D ; ...

Embodiment 2

[0030] 1) Lindao 10, a disease-resistant semi-dwarf non-light-sensitive medium growth stage green-leaf rice variety, was selected as the recurrent parent R, purple-leaf rice variety IR1552(A), yellow-leaf rice variety Huangyu B(B), and rice striped flower were selected. The leaf mutant st(t)(C) and the yellow-green leaf rice variety ygl10(D) are the parents for the introduction of leaf color traits, and crosses R / A, R / B, R / C, and R / D to obtain hybrid F 1 Substituted by F 1 - A , F 1 - B , F 1 - C , F 1 - D express;

[0031] 2) planting F 1 - A , F 1 - B , F 1 - C , F 1 - D , backcross with the recurrent parent R at the flowering stage to obtain the backcross F1 generation, respectively with BC 1 f 1 - A 、BC 1 f 1 - B 、BC 1 f 1 - C 、BC 1 f 1 - D express;

[0032] 3) Plant BC 1 f 1 - A 、BC 1 f 1 - B 、BC 1 f 1 - C 、BC 1 f 1 - D , respectively harvested to get BC 1 f 2 - A 、BC 1 f 2 - B 、BC 1 f 2 - C 、BC 1 f 2 - D ;

Abstract

The invention discloses a selective breeding method of ornamental colorful rice varieties and belongs to the technical field of breeding of ornamental rice. The method is characterized by selecting a disease-resistant short-stem green leaf rice variety as a recurrent parent R, respectively hybridizing the disease-resistant short-stem green leaf rice variety with a purple-leaf rice variety, a yellow-leaf rice variety, a streak-leaf rice variety and a yellow-green-leaf rice variety, and backcrossing later generations with multiple generations of the recurrent parent; and selectively breeding near-isogenic line strains with agronomic characters similar to the recurrent parent and target leaf color characters, and planting according to a certain pattern to plant a rice field picture. The planted different-colored rice strains of the ornamental colorful rice varieties which are selectively bred by the method are uniform in shape, agronomic characters and growth and development stages; the pattern of the rice field picture is clear in color layers and stable in pattern effect in various stages of growth and development of the rice.

Description

technical field [0001] The invention specifically relates to a breeding method for ornamental colored rice varieties, and belongs to the technical field of ornamental rice breeding. Background technique [0002] Paddy painting is a Japanese art form in which farmers create paintings by planting various varieties of rice in rice fields. Mainly green and purple leaf rice is planted in the paddy fields. When planting, first use a traditional liner in the farmland to determine the coordinates according to the pattern, then draw the pattern or outline of the font with a line, and finally plant purple seedlings. As the rice grows, Pre-planned graphics or text will be presented. Inakadate Village, Aomori Prefecture, Japan holds a "Paddy Field Art Festival" every year to display rice field paintings made by farmers to attract tourists. Now rice field paintings appear all over the world. In recent years, there have been reports of creative rice field painting planting by farmers f...
