Embodiment 1

[0049] The present embodiment provides a kind of method for manual rapid identification capsicum fruit cracking resistance, and this method specifically comprises the following steps:

[0050] Step 1: Select the capsicum cracking-resistant strain 112-1 as the cracking-resistant control, and select the capsicum cracking-resistant strain Sy06 as the easy-cracking control; select the cracking-resistant control's fruit in the veraison period and the cracking-resistant control's fruit in the veraison period as the identification cracking-resistant fruit sexual samples;

[0051] Step 2: Select fresh capsicum veraison fruits with unknown resistance to fruit cracking as samples to be tested, and put the samples to be tested into gauze bags according to strains, with 5 fruits in each bag, tie the mouth of the gauze bag and label the strains name;

[0052] Step 3, then submerge the gauze bag containing the sample to be tested in an aqueous NaCl solution with a mass concentration of 0.5...

Abstract

The invention provides a method for rapidly artificially identifying the fruit cracking resistance of chili. The method comprises the following steps: soaking a to-be-detected sample which is a chilifruit at the turning stage in a NaCl aqueous solution having a mass concentration of 0.05 percent; and standing in an artificial climate tank of 26+ / -2 DEG C, and continuously treating for 24 hours toobtain a cracked fruit sample. According to the method for identifying the fruit cracking resistance of chili by utilizing in-vitro fruits at the turning stage, fresh fruits of a plant at the turningstage are collected for testing, and chili strain or the fruit cracking resistance of a strain can be identified by calculating the fruit cracking index. The method is stable and reliable, the identification result is in accordance with years of field natural identification results, the repeatability is good, speed is high, time and labor are saved, the efficiency for screening the fruit crackingresistant strain can be effectively improved, the breeding process is accelerated, and research and development of chili fruit cracking resistance molecular markers and gene clone can be favored.

Description

technical field [0001] The invention belongs to the field of vegetable breeding, relates to capsicum, in particular to a method for artificially quickly identifying the fruit-cracking resistance of capsicum. Background technique [0002] Fruit cracking is a common physiological disease in agricultural production. In tomato production, it has been found that uneven water supply is an important cause of fruit cracking (Ru Xuejuan et al., 2011). At the same time, high temperature and strong light directly irradiating the tomato fruit surface are also important factors leading to fruit cracking (Peet M., 1992). Reasonable application of potassium, calcium, and magnesium fertilizers can significantly reduce the occurrence of tomato fruit cracking (Ru Xuejuan et al., 2014). It can be seen that environmental factors and soil nutritional status are closely related to tomato fruit cracking. [0003] Similar to tomato, capsicum (Capsicum annuum L.) fruit cracking is also a common p...
