Embodiment 1
[0035] Embodiment 1, pear breeding
[0036] 1. Hybridization (carried out in Tarim, Xinjiang)
[0037] In April 2003, the pollen of ‘Laiyangci’ pear was used to pollinate the emasculated ‘Xinli No. 7’ pear, and the F 1 hybrid seed, the F 1 After the hybrid seeds are washed, they are placed in a fresh-keeping room of a refrigerator at 1-3°C for stratification treatment for about 60 days (the purpose is to release the dormancy of the seeds by satisfying the required cooling capacity).
[0038] 2. Greenhouse seedling cultivation (in Tai'an, Shandong)
[0039] In December 2003, the F obtained in step 1 1The hybrid seeds are sown in a nutrient pot (3-5 seeds are planted in each nutrient pot) that is equipped with a seedling-raising substrate and cultivated until the seedling height is 8-15cm and the root neck is lignified (usually 2-3 months for sowing), and then The seedlings are transplanted to new nutrient pots (every nutrient pots are transplanted with 1 plant) that are equ...
Embodiment 2
[0048] Embodiment 2, pear breeding
[0049] Replace the 'Laiyang Ci' pears with 'Dangshansu' pears, and the others are the same as in Example 1.
[0050] A plant with the best performance was named 'CSSL-777'.
[0051] The other two plants with excellent performance were named 'Shannong Suli No. 2' and 'Shannong Suli No. 3' respectively.
