Problems solved by technology

The cotyledon purple trait in the present invention is genetically stable, and its performance is not affected by climate, cultivation conditions, etc., so that the pseudo hybrid can be stably identified from the hybrid population when the cotyledon is unfolded, and the hybrid purity identification result is reliable, fast and accurate. The purity identification period only needs about 10 days, and the purity identification cost is reduced by 90%; the false hybrids with normal green cotyledons can also be pulled out at the seedling stage in production, reducing the economic loss caused by the purity of the hybrids; but there are still certain defects. The use of cotyledons for production and identification is generally only applicable to the pepper variety 9004 purple with purple cotyledons, and the seedling marker traits with purple cotyledons can only be used within the scope of this variety and cannot be widely promoted

Embodiment example 1

[0021] To produce the "Xingshu 215" hybrid, the pepper variety 2144 Bai with a white style is used as the female parent and the pepper variety 8214 Zi with a purple style is used as the male parent for hybrid seed production.

[0022] 1. Sow at the right time. According to the maturity of the parents, the male parent should be sown early. The male parent and the female parent should be sown separately and marked on the label. Sow 1 to 2 seeds per hole, and the amount of seed per mu is 25 to 30g. It is suitable for seedling sheds. The temperature is 25-30°C during the day and about 18°C ​​at night to prevent excessive growth. When hybrid seedlings are found, they should be pulled out in time, and the seedlings will be seedlings with two leaves and one heart.

[0023] 2. The planting ratio of parents is generally 1:3~5, planted in different areas and listed on signs.

[0024] 3. Ensure that there are no other crops within 100 m of planting hybridization; the soil is relatively f...

Embodiment example 2

[0032] The production of "Xingshu Yuyan" hybrid is basically the same as the production and purity identification method of the implementation case 1. The difference is that the pepper variety 05S180 white with a white style is used as the female parent and the pepper variety 8214 purple with a purple style is used. Male parent for hybrid seed production.

[0033] The Xingshu Yuyan produced by the above-mentioned production method and purity identification method is pulled out of the false hybrid. It is horn-shaped and slightly spicy, with a fruit length of 22cm and a transverse diameter of 2.6-2.8cm. The green fruit is light white, resistant to TMV and CMV, and is suitable for protection. Cultivated in the open field and in the north.

[0035] The production and purity identification methods of the "Bo La No. 15" hybrid are basically the same as those in Example 1. The difference is that the pepper variety LS21 White with a white style is used as the female parent and the pepper variety J0721 Purple with a purple style is used as the female parent. Male parent for hybrid seed production.

[0036] Bo La No. 15 produced by the above-mentioned production method and purity identification method is a late-maturing line pepper, with a fruit length of 25 cm and a transverse diameter of 1.4-1.6 cm. The green fruit is dark green. It is eaten fresh or chopped or made with sauce. High-yielding cultivation in protected or open fields.

Abstract

The invention discloses a method for producing a hot pepper hybrid and a purity identification method, and belongs to the field of hybrid hot pepper seed production. The method for producing a hot pepper hybrid is characterized in that a hot pepper variety with styles of dominant character color is used as a male parent, and a hot pepper variety with styles of recessive character color is used asa female parent for hybrid seed production; the style color of the male hot pepper variety is purple; the style color of the female hot pepper variety is white; the hot pepper variety with purple styles is 8214 purple or J0721 purple; both indoor planting and field planting can be carried out; the identification time is shortened, fruit setting and bud unfolding are not needed for identification,the hybrid purity identification result is reliable, rapid and accurate, and the purity identification period only needs about 30 days; the identification cost is decreased by higher than 80%; and theproblems of large error, long time and high cost in purity identification of hybrid hot pepper at the present are solved.

Description

technical field [0001] The invention relates to the technical field of hybrid capsicum seed production, in particular to a production method and a purity identification method of a capsicum hybrid. Background technique [0002] Hybrid peppers play a very important role in the production and supply of vegetables in my country. At present, the method of manual removal of pollination is mainly used in the production of hybrid pepper seeds, and the method of artificial emasculation and pollination is used to produce hybrids. Thorough and untimely waiting to produce fake hybrids can easily cause economic losses. [0003] At present, the main method for identifying the purity of hybrid pepper seeds is field identification. Plant the sample seeds of the hybrid seeds in the field, observe the agronomic traits of the plants, such as fruit, plant height, plant width, leaf shape, etc., if the traits are consistent with F1, then judge For F1 hybrids, this method is the most widely used....
