Baye silk seedling (rice)

Bayesi Miao is a new variety of silky rice selected by the seed Station of Zengcheng Bureau of Agriculture, which uses many excellent germplasm cross genetic breeding methods at home and abroad. The parents are: Basmati 370 Dynamax / Guiye Zhan 3 / LABELLE// Black Wild Silk Miao 21. The excellent strains of Baye silk seedling are No.1 and No.2.

Production performance: the results of the comparison test of early varieties in 2000: the yield of Bayesi Miao No. 1 was 399 4 kg per mu, which was 18.6 kg higher than that of the control, an increase of 49%, and a significant increase. The results of late re-test showed that the yield of Baye Silk Miao No. 1 was 39565 kg per mu, an increase of 47.82 kg per mu and 13.75% higher than that of Guiye Silk Miao No. 1, while that of Baye Silk Miao No. 2 was 400 kg per mu, an increase of 52.17 kg per mu and 15% higher than that of Guiye Silk Miao No. 1. The increase in production is extremely significant and the performance is outstanding. The field production demonstration at the same time shows that it has wide adaptability and high and stable yield. Planted late in 2001, the average yield per mu was 446 kg, which was more than 15% higher than that of other varieties. The yield of field production is about 450 kg per mu, and that of high-yield cultivation is more than 500 kg per mu.

Variety characteristics: early planting and middle maturity, the whole growth period is 122 days. The leaf age is 14. Short stalk, fertilizer resistance and lodging resistance, moderate distribution of plant type, ideal stem state, strong tillering ability, good late ripening color, green branch and wax draft, large panicle, high seed setting rate, 1000-grain weight 17.4 g. Lemma color, Baye Simiao No. 1 light yellow, Ba Yesi Miao No. 2 white. Rice grain is slim, crystal clear and white, glassy, without belly and white heart. The grain of rice is soft and hard, and the meal tastes good. The variety is coarse and easy to manage, wide adaptability, early and late cropping, strong disease resistance, high and stable yield. According to the survey, the general production of field (throwing seedlings) basic seedlings 740000, the highest seedlings 2.83 million, effective panicles 18.07 million, the average total grains per panicle 181,170, seed setting rate 939%, 1000-grain weight 18 grams. The plant height is 97 3 cm, the ear length is 23 7 cm, and the flag leaf is 34 1 cm long and 1 9 cm wide. According to the on-the-spot investigation by experts and professors organized by Guangdong Genetics Society, it is generally believed that the variety has ideal stem type, good high yield, excellent rice quality and strong resistance, and has a prospect of popularization. The Zengcheng Variety Identification meeting agreed that the variety has wide adaptability, strong resistance, good performance of high and stable yield, excellent rice quality and good rice taste. It is a good new variety of silk seedling rice, which can be expanded and demonstrated.

Fertilizer and water management of throwing seedlings: the amount of seed used per mu is 1.5 kg. To cultivate strong seedlings of appropriate age, generally throwing seedlings at the age of 3 or 5 leaves. Apply sufficient base fertilizer in the field and 20 kg phosphate fertilizer per mu. The tiller and strong stalk fertilizer was applied early and potassium fertilizer was re-applied at the stage of young panicle differentiation. Late planting is suitable for the application of strong tail fertilizer. Scientific use of water, enough seedlings to open fields, moderate drying in the middle period.
