摘要：

Chakhao is a popular pigmented black rice variety with remarkably high anthocyanin content. Due to its susceptibility to various biotic and abiotic stresses, its production has remained low. Here, two genes, Pi54 blast-resistant and OsSPL14, high-yielding genes of rice, were pyramided in a Chakhao landrace by crossing with CR Dhan 307. From a total of 147 F-4 lines developed, 32 were identified with the positive alleles of both genes, of which 16 were black grain coloured, and their total anthocyanin content ranged from 30.19 +/- 2.19 to 240.31 +/- 2.62 mg 100 g(-1) dried weight. Among these, ChM 68 F-4 line had the highest anthocyanin content (240.31 +/- 2.62 mg 100 g(-1) of powdered grain) with more 118.96 mg 100 g(-1) anthocyanin than the recipient parent, CHK13 (121.35 +/- 3.32 mg 100 g(-1)), making it a promising line to be released as a high-yielding and durable blast-resistant Chakhao variety in Manipur.
