Introduction to Upland Rice Varieties Suitable for Planting in the North

Upland rice is also called dryland rice. It is an ecotype crop formed through long-term domestication and evolution of rice under dryland conditions without a water layer. Planting upland rice is divided into spring sowing and summer sowing. Spring sowing can be carried out from mid-April to mid-May, with mid-May being preferable. For summer sowing, sowing before June 15 is preferable, and the earlier the better. Farmers who grow upland rice all know that areas south of 38 degrees north latitude can grow upland rice without risk, so what varieties of upland rice are there for planting in the north?

1. Mountain Rice

Mountain rice is a general category of upland rice, referring to rice with such high water-draining ability that it not only does not need to be planted in paddy fields but can also survive in water-scarce hilly land. Historical records show that the earliest large-scale cultivation appeared in the hilly areas of northern China. It has characteristics such as not occupying cultivated land, not applying pesticides or chemical fertilizers, not spraying herbicides, and not requiring manual watering.

2. Danjing No. 5

Danjing No. 5 takes about 140 days from emergence to maturity and belongs to the mid-to-late maturing variety. Plant height is 86.4 cm, with thick and sturdy stems, relatively wide and short leaves that point upward, and dark green leaf color. The plant type is relatively ideal, with a well-developed root system and strong tillering ability. The rice quality has good palatability, and it has strong drought resistance. It is a new variety for water-saving rice cultivation.

3. Danjing No. 6

Danjing No. 6 is a new dryland rice variety bred through hybridization by the Dandong Academy of Agricultural Sciences. It takes 130 days from emergence to maturity and belongs to the medium maturing type variety. Plant height is 89 cm, with relatively wide and long leaves that droop and bend in the early stage and point upward in the later stage. Leaf color is green, tillering ability is medium, and the root system is well developed. It has strong drought tolerance, is relatively resistant to rice blast, and resistant to rice false smut. The rice quality has good palatability.

4. Upland Rice 297

Upland Rice 297 belongs to the japonica-type conventional upland rice variety, with a growth period of about 136 days. The stems are thick and sturdy, and the leaves are relatively wide and long. At the full heading stage, the lower leaves droop and soften while the upper leaves stand upright, and the leaves curl slightly inward. The leaf color is green, and the yield is relatively high.

The above are varieties of upland rice in the north. On one hand, upland rice has drought resistance; on the other hand, it still has the water-loving nature of rice. Areas with abundant rainfall are more conducive to the growth and high yield of upland rice. Farmer friends in northern regions who plant upland rice may consider the above varieties.
