Edible Gardening 0 views
Liaoyou 1052 is a new hybrid aromatic rice combination developed by the Rice Research Institute of Liaoning Province, crossing a fragrant rice male-sterile line with a high outcrossing rate and a high-quality restorer line. Characteristics: The growth period of Liaoyou 1052 is about 158 days, the plant height is 116-118 cm, the average panicle length is 19.35 cm, the total number of spikelets per panicle is 180, and the number of filled grains is 140. It belongs to the large-panicle type of rice combination, with a 1000-grain weight of 24.6 g. After transplanting, seedlings establish quickly, individual plants grow vigorously, and tillering ability is moderate, with an average of 15 panicles per hill and a high productive-stem rate.

Characteristics

The growth period of Liaoyou 1052 is about 158 days, the plant height is 116-118 cm, the average panicle length is 19.35 cm, the total number of spikelets per panicle is 180, and the number of filled grains is 140. It belongs to the large-panicle type of rice combination, with a 1000-grain weight of 24.6 g. After transplanting, seedlings establish quickly, individual plants grow vigorously, and tillering ability is moderate, with an average of 15 panicles per hill and a high productive-stem rate. The stems are thick and strong, with strong lodging resistance, strong drought resistance, and strong salt-alkali tolerance. The cooked rice is soft and has a distinctive fresh aroma, comparable to Japan's high-quality rice Koshihikari, with an excellent taste.

Yield Performance

In 2002, a trial planting was carried out in Luobo Village, Bali Town. Even though it encountered flooding during the flowering and pollination period, the yield still reached 600 kg per mu.

Cultivation Points

Sow early at the appropriate time, sow sparsely, and cultivate strong seedlings with tillers. Maintain an appropriate spacing between plants and rows, generally 33.3 x 16.7 cm, with 3-4 seedlings per hill. Fertilize rationally, advocating the principle of heavy application early and light application later.
