“JJ603Balck” is a mid-late maturing high-yielding black rice having multiple-disease resistance. It was developed to increase the yield and disease resistance of Korean black rice. “JJ603Black” was derived from a cross between “Heughyang” and BC2F1 plants (Hopum*3/SR30075-1-12-6-1-1-1). “Heughyang” is a mid-late black rice with a short culm, while “Hopum” is a mid-late maturing rice cultivar with high yields and premium quality, and “SR30075” is a pyramid line carrying three bacterial blight resistance genes. “JJ603Black” was selected through the pedigree method, yield trials, and local adaptability tests, with a high selection pressure for black pericarp, resistance to bacterial blight K3a race, and high yield performance. The heading date of “JJ603Black” was August 19, 8 d later than that of “Heugnam,” which is the standard cultivar for black rice. “JJ603Black” is a cultivar tolerant to lodging with erect plant architecture. It showed multiple-disease resistance against bacterial blight and rice stripe virus owing to introgression resistance genes, Xa3+Xa21+Stvb-I; moreover, its yielding performance was high. The average brown rice yield of “JJ603Black” from 2016 to 2018 was 6.02 MT/ha, which was 14% more than that of “Heugnam” (5.30 metric/ha). Further, the anthocyanin content of “JJ603Black” (58 mg/100 g) was higher than that of “Heugnam” (51 mg/100 g). Therefore, “JJ603Black,” a high-yielding black rice cultivar with multiple-disease resistance, can be utilized for enhancing the disease resistance and yield of Korean black rice (Registration No. 7274).
