Embodiment 1

[0047] The rapid screening method of high hot pepper breeding resource of the present invention comprises the following steps:

[0048] 1. Sampling

[0049] Pepper breeding resource materials are planted in plots with consistent soil fertility and other environments, and fertilizer and water are supplied according to the law of pepper water and fertilizer demand. During the commercial maturity period of peppers, pick peppers that meet the maturity of the commodity, including red ripe fruits and green ripe fruits. Pick 15-20 peppers for each material, pick 12-15 materials every day, and measure immediately after picking. In order to reduce the error between materials, the present invention measures and picks the capsicum fruit of section 2-5. At the same time, put them into 100pk ziplock bags immediately after picking, the size depends on the pepper fruit, usually 140mm×200mm, and store them at room temperature.

[0050] 2. Construct a simple and rapid method for determining...

Embodiment 2

[0082] Embodiment 2, the concrete application of capsicum fruit pungency screening method of the present invention

[0083] The rapid screening method of high hot pepper breeding resource of the present invention specifically comprises the following steps:

[0084] (1) Sampling

[0085] Sampling (picking the pepper fruit of section 2-5; taking the fruit of 1 / 3-2 / 3 of the pepper, and removing the pepper seed) for the red ripe pepper fruit of 14 breeding materials;

[0086] (2) Use the electronic nose device to measure the pepper spiciness

[0087] Accurately weigh the sample to be tested, store it in a 100ml hotness measuring device, let it stand for 30 minutes, and use the PEN3 electronic nose for detection;

[0088] The cleaning time of the electronic nose sensor is 70s. Based on the value of the 56th second when the electronic nose measures the hotness of pepper as the experimental time point, the values ​​​​of the electronic nose W5S, W1W, and W2W sensors are added.

Embodiment 3

[0098] The screening method of the present invention is used to sample the pepper fruits in the green maturity stage of 14 breeding materials, and measure the hotness of pepper (the specific steps are as shown in Example 2). Take the mean value of three biological repetitions of each variety, and organize the data, as shown in Table 8, it is found that the sensory evaluation is not hot pepper green fruit, and the sum of the W5S, W1W, and W2W values ​​​​is between 1 and 10; the sensory evaluation is The sum of the spiciness values ​​of the W5S, W1W, and W2W sensors for slightly spicy green peppers is between 10.1 and 20; the sum of the spiciness values ​​of the W5S, W1W, and W2W sensors for spicy green fruits is between 20.1 and 20.1 50; Among them, the sum of the measured values ​​of W5S, W1W, and W2W sensors in the green ripening stage of the devil pepper is also greater than 50.1, which is consistent with the super spicy sensory results, proving the correctness of the electro...

Abstract

The invention provides a rapid screening method of high-pungency chili breeding resources. The screening method provided by the invention can be used to obviously distinguish the pungency among breeding materials, and the fact that an electronic nose can be used for evaluating and distinguishing the pungency of chilies is determined. On the basis, the fact that the electronic nose can quantify thepungency of breeding materials is also determined, and the index threshold value is screened. The screening method provided by the invention can be used to easily and quickly screen breeding resourcematerials, namely, the pungency level of the chilies is divided, and the pungency is divided into four levels including not spicy, slightly spicy, spicy and super spicy. The screening method providedby the invention is established on the basis of scientific experiments, and screening and determination are carried out through specific screening examples. The screening method provided by the invention not only can be applied to fast screening of high-pungency chili breeding resources, but also can be used for evaluating raw materials of chili processing industries. Constant pungency of chili products is determined, and the screening method has an excellent market application prospect.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a rapid screening method for breeding resources of high-spicy peppers. Background technique [0002] Pepper is one of the vegetable species with the largest planting area in my country. Since it was introduced from South America, it has been widely distributed. In addition, my country has a vast territory, complex climate and soil types, and diverse cultivation systems, forming a very rich pepper germplasm resource. There are many kinds of peppers, mainly including long peppers, cherry peppers, and cone peppers, including lamb's horn peppers and wire peppers. With the development of the world's catering industry and food processing industry, the consumption of capsicum and capsicum products is increasing rapidly. Therefore, capsicum has become one of the vegetables with the fastest growth rate of production in the past ten years. Capsicum can be used not only as a f...
