Which rice varieties are national standard first-grade rice? A roundup of the rice variety list
Hunan is the hometown of hybrid rice. Generally, the yield of hybrid rice is about 20% higher than that of conventional rice, which is naturally better for farmers. However, for a long time, the high yield and high quality of hybrid rice could not coexist, until recently, when hybrid rice varieties with national standard first-grade quality rice appeared. They are "Yueliangyou 2646" for middle-season rice cultivation and "Taiyounong 39" for late-season rice cultivation, and they have become rice varieties very popular among farmers. Let's take a look together!
1. Variety: Yueliangyou 2646
Characteristics: This variety is a representative new two-line hybrid rice variety with a major breakthrough in the past 30 years, and belongs to indica conventional rice. It has been listed by the state as national standard first-grade rice quality. When planted as double-season early rice in the middle and lower reaches of the Yangtze River, the average whole growth period is 109.0 days. The plant type is moderate, the tillering ability is medium, the stems are thick, and the color changes well at maturity. The plant height is 88.4 cm, the panicle length is 18.0 cm, and the effective panicle number per mu is 206,000 panicles.
Yield performance: Through the regional trial of early-mid-maturity early indica varieties in the middle and lower reaches of the Yangtze River, the average yield per mu is generally 500-540 kg. The yield is very astonishing.
Suitable range: Suitable for planting as early rice in double-cropping rice areas in Jiangxi, Hunan, Anhui, and Zhejiang where rice blast and bacterial blight occur lightly. In the past three years, the promoted area in Guangxi, Jiangsu, Hunan, Zhejiang, Anhui and other provinces has reached 29.31 million mu.
2. Variety: Taiyounong 39
This variety is a very famous three-line hybrid rice. Like Thai rice, it has a short plant, strong lodging resistance, and a moderate growth period. It saves labor in planting, emerges quickly, and has a high survival rate. It is suitable for direct seeding and mechanized harvesting. In trials in 7 provinces and regions including Guangdong, Hunan, Hubei, Guangxi, Hainan, Zhejiang, and Jiangsu, it consistently showed excellent characteristics of high and super-high yield, high quality, strong stress resistance, and wide adaptability.
Yield performance: Through the regional trial of conventional high-quality rice in the early crop, the average yield per mu is generally 500-680 kg. The yield is very good and suitable for large-scale planting.
Suitable range: Suitable for planting in Guangdong, Guangxi, Hainan, Hunan, Hubei, Jiangxi, Chongqing and other provinces and municipalities.
In summary, the significance of hybrid rice quality reaching national standard first grade for rice development is very great. This also provides farmers with the opportunity to plant high-quality, high-yield rice. I hope this article is helpful to everyone.
