Introduction of two new combinations of early brilliant rice with high yield, medium maturity and high quality

T you 898: a new early indica rice combination selected by Hunan Longping Hi-Tech Nongping seed Industry Co., Ltd. In 2005, it passed the variety approval of Jiangxi Province (approval No.: Ganzhendao 2005080L)

Characteristics: cultivated as early rice in Jiangxi, the whole growth period is about 115 days. The plant height is 95 cm, the plant and leaf type is good, the tillering ability is strong, the stem is stout, the panicle rate is high, the color is good in the later stage, and there is no grain drop. The effective panicle of 667m2 (1 mu) is 220000, the total grains per panicle is 119.6, the weight of 1000 grains is 24.7g, the grain is slender, the ratio of length to width is 3.2and the appearance quality is excellent. The resistance in the field is good. Generally, the yield of 667 square meters is 460,500 kg, and the high yield cultivation can reach 525,550 kg.

Cultivation points: suitable for medium fertilizer level cultivation. Sowing in the middle and last ten days of March (various places can refer to the sowing date of Jinyou 402), sparsely sowing and evenly sowing strong seedlings, the seed consumption of 667 square meters in the field is 1.5kg and 2.0kg. The seedling age is 25 ~ 30 days, and the planting specification is 17 cm × 20 cm, with 2 seedlings in each hole, ensuring that 70,000 ~ 80,000 basic seedlings are planted in 667 square meters. Fertilization is mainly based on base fertilizer, early topdressing, shallow water tillering, enough seedling drying, controlled application of nitrogen fertilizer in the middle and later stage, dry and wet strong seeds, moist root maintenance, and water cut off too early in the later stage. It is suitable to be planted in the areas with light incidence of rice blast in central and southern Jiangxi, and can be introduced and planted in neighboring provinces.

Jinyou 898: a new hybrid early indica rice combination selected by Hunan Longping Hi-Tech Nongping seed Industry Co., Ltd. It passed the variety approval of Jiangxi Province in 2005 (approval No.: Ganshendao 2005077) and Hunan Variety examination and approval of Hunan Province in 2006 (approval number: Xiangshendao 2006009).

Characteristics: cultivated as early rice in Jiangxi, the whole growth period is about 115 days. The plant height is 85-90 cm, compact plant type, strong tillering ability, more effective panicles, strong lodging resistance, no grain drop, good color change at ripening stage and wide adaptability. The effective panicle is 230000 per square meter, the total number of grains per panicle is 102.9, the weight of 1000 grains is 26.0g, the grain is slender and the ratio of length to width is 3.0. The resistance in the field is good. Generally 667 square meters yield 450 million 500 kilograms, high-yield cultivation can reach 525 million 550 kilograms.

Cultivation points: sowing in the middle and late March, sparse sowing, evenly sowing strong seedlings, field 667 square meters seed consumption 1.5-2.0 kg. The seedling age is 30 days, and the planting specification is 17 cm × 20 cm, with 2 seedlings in each hole, ensuring that the basic seedlings are planted in an area of 667 square meters. Fertilization is mainly based on base fertilizer, early topdressing, and late seedling application of strong seed fertilizer to prevent greed and green, shallow water tillering, enough seedling drying, dry and wet strong seeds, moist root maintenance, and water cut off too early. It is suitable for planting early rice in the areas with light incidence of rice blast in Jiangxi and Hunan.
