Lentil (Lens culinaris Medik) is the third-most important grain legume in the world. In Bangladesh, it is important for human food and nutrition, animal feed, and sustainable rice-based cropping systems. However, lentil area is declining due to competition with other winter and spring crops, particularly irrigated spring rice (boro rice; Oryza sativa L.). To increase lentil production, the extra-early (<95 d) lentil line LRIL-22-70 was selected to grow in the short fallow period between monsoon and spring rice under a proposed new cropping pattern. LRIL-22-70 was identified from a recombinant inbred line population through rigorously evaluated in diverse agro-ecological conditions of Bangladesh and released for commercial cultivation by Pulses Research Centre, BARI, as ‘BARI Masur-9’ (Reg. no. CV-36, PI 700307) in 2018. BARI Masur-9 is a transgressive segregant for earliness (matures in <93 d) and fits well in the new monsoon rice–lentil–spring rice cropping pattern. It is a medium-seeded (2.38 g 100–1 seed) cultivar with high tolerance to Stemphylium blight. The average seed yield of BARI Masur-9 was 1,201 kg ha–1, with higher concentrations of Fe (73 mg kg−1) and Zn (61 mg kg−1) compared with other genotypes; thus, BARI Masur-9 contributes to combatting micronutrient malnutrition in Bangladesh. BARI Masur-9, the first extra-early lentil cultivar, can successfully be grown to replace fallow between rice as a new cropping pattern monsoon rice–lentil (BARI Masur-9)–spring rice in about 8 million ha in Bangladesh, eastern Indian states, and eastern Nepal.
