Abstract:
Jiahe 165 was a conventional rice variety with high quality, disease resistance, high yield and lodging resistance after many years of breeding, which was bred by the College of Life Science of Xiamen University. This variety was bred by crossing the high-quality early rice variety Jiafuzhan as the female parent with the high-quality large-grain material Jiafu 42 created by the irradiation mutagenesis of mature pollen as the male parent, and then recrossed with the introduced high-quality rice variety Yuejingsimiao. The whole growth period of Jiahe 165 was about 122 days, which was equivalent to that of Tianyouhuazhan (CK). The yield level of this variety was high, with the average yield being 8859.5 kg·hm
-2 in the regional test, and the average yield in the 100 mu demonstration plot of high-yield cultivation reaching 8904.00 kg·hm
-2. Jiahe 165 showed medium resistance to the rice blast and its grain quality accorded with the quality standard of the first-class high-quality edible rice varieties issued by the Ministry. The rice quality had good stability and it was also resistant to high fertilizer level and lodging. Jiahe 165 was approved by Fujian Crop Variety Approval Committee in 2021 (Minshendao 20210039) and has been popularized and applied in the production.
