Introduction to the Characteristics and Traits of the Rice Variety Liaonong 968

I. Origin:

Liaonong 968 was bred by the Institute of Crop Cultivation of the Liaoning Academy of Agricultural Sciences from natural hybrid progeny of C57.

II. Characteristics and Traits:

1. Morphological characteristics: plant height 100CM, strong tillering ability, panicle length 17-18CM, 90-100 grains per panicle, high seed-setting rate, awnless, semi-erect panicle type, leaves upright.

2. Growth period: the growth period is about 158 days, 1-2 days earlier than Liaojing 294, and 1-2 days later than Liaojing 454-17.

3. Resistance: moderately resistant to rice blast, slightly susceptible to rice false smut.

III. Grain Quality and Yield:

High milling yield with no white belly, grain quality better than 454. High yield, generally 550-600 kg per mu, and high-yield fields can reach more than 700 kg. The panicle is slightly larger than that of 294, so the yield is also higher than that of 294.

IV. Key Cultivation Points

Use dry seedling raising to cultivate strong seedlings. Because of strong tillering ability, sparse planting is suitable, with row spacing and plant spacing of 9×5 cun, and 2-3 seedlings per hill. Apply sufficient base fertilizer and topdress in a timely manner. Base fertilizer: 20 kg of ammonium sulfate and 10 kg of diammonium phosphate. After seedling recovery, apply 20 kg of ammonium sulfate mixed with herbicide broadcasting, topdress 15 kg of tillering fertilizer at the tillering stage, and topdress 5-7 kg of panicle fertilizer in mid-July. Carry out shallow-water irrigation; after enough tillers have developed, drain and sun the field to promote root development and prevent lodging. After the rows close, use shallow-wet irrigation, with the later water not visible before the earlier water; do not withdraw water too early before harvest to prevent premature senescence. Apply pesticide in mid-July to control the Asiatic rice borer, and apply pesticide once 10 days before heading and once at full heading to control rice false smut and rice blast.

V. Suitable Regions:

Plain rice areas such as southern Shenyang, Liaoyang, Anshan, Haicheng and Jinzhou
