Successful breeding of the new upland rice variety Xiahan 51

This achievement is an early-maturing japonica-type upland rice with strong drought resistance, high yield, and average grain quality. It is susceptible to rice blast and resistant to narrow brown leaf spot, and is suitable for upland cultivation. Plant height is 86.8 cm, the plant type is relatively compact, the leaves are erect at the seedling stage, the leaf color is dark green, and growth is steady; growth is vigorous in the mid-to-late stages, with relatively high tillering ability and productive tiller rate, and relatively strong lodging resistance. Panicle length is 15.1 cm, total grains per panicle are 88-90, seed-setting rate is 90%, and 1000-grain weight is about 25 g. Disease resistance: leaf blast grade 3, neck blast grade 7, narrow brown leaf spot grade 1. Main grain quality indicators: head rice rate 64.5%, length-to-width ratio 1.6, chalky grain rate 90%, chalkiness degree 27.1%, gel consistency 71 mm, amylose content 16.1%.
