Last Updated: 2024/11/09, The main results are as follows: (1) Variety source: Jinyou 2248 is a medium indica medium maturing hybrid rice combination made by Jin 23A2248 from Chengdu Institute of Biology, Chinese Academy of Sciences. (2) characteristics: the growth period of the combination is 147 days, the plant height is 110 cm, the average grain per panicle is 130, the seed setting rate is more than 80%, and the 1000-grain weight is 27-28 g. The plant has good leaf shape, strong tillering ability, erect leaf and dark leaf color. Most of the rice quality reaches the first-or second-grade high-quality rice standards issued by the Ministry. Disease resistance identification of leaf blast grade 4-5, neck temperature grade 2-5, light sensation pattern in the field.

(1)Jinyou 2248 is a medium indica hybrid rice combination developed by crossing Jin 23A2248 with Chengdu Institute of Biology, Chinese Academy of Sciences.

(2)Characteristics: The growth period of this combination is 147 days, the plant height is 110 cm, the grain per panicle is 130, the seed setting rate is more than 80%, and the 1000-grain weight is 27-28 g. Plant leaf type is good, tillering is strong, leaf is erect, leaf color is darker. Most of the rice quality reached the first or second grade high quality rice standard issued by the Ministry. The disease resistance was identified as 4-5 grade of leaf blight, 2-5 grade of neck temperature, and light susceptible to sheath blight in field.

(3)Yield performance: In 1995-1996, the average yield per mu was 500.35 kg, which was 1.45% higher than that of control Shanyou 195. In 1997, the average yield per mu was 526 kg, which was equivalent to Shanyou.

(4)Cultivation points: timely sowing, cultivation of multi-tiller strong seedlings, planting 100 - 200,000 basic seedlings per mu; fertilizer pipe buried should be applied with sufficient fertilizer base, increased phosphorus and potassium fertilizer, timely light application of ear fertilizer, late water cut time appropriately postponed.

(5)Adapt to planting areas: adapt to flat dam, hilly areas and similar areas outside the province planting.
