‘BARI Masur-8’: A high-yielding and biofortified lentil cultivar in Bangladesh

Abstract

Lentil (Lens culinaris Medik.) is a nutritious food for millions of people globally. It plays an important role in Bangladesh as a good source of protein and micronutrients for low-income populations with less access to animal protein. To enhance nutritional security, a nutrient-dense lentil line, LR-9-25, was identified from a Stemphylium blight (SB) screening population developed at The International Center for Agriculture Research in the Dry Areas through a cross between ILLX955-135 and FLIP92-52L. The line LR-9-25 was rigorously evaluated in diverse agro-ecological conditions of Bangladesh and released for commercial cultivation by the Pulses Research Centre, Bangladesh Agricultural Research Institute as ‘BARI Masur-8’ (Reg. no. CV-35, PI 700306) in 2015. BARI Masur-8 matures in 115–120 d and fits well into existing rice-based cropping patterns. It is a medium-height (35 cm) and medium-seeded (1.94 g 100−1 seed) cultivar having a high level of tolerance to SB and root rot diseases. BARI Masur-8 showed high yield potential (1,973 kg ha−1) and high concentrations of Fe (74 mg kg−1), Zn (61 mg kg−1), and Se (325 μg kg−1) in seed. Another desirable trait is the late planting potential, with sowing up to the first week of December after the harvest of long-duration rice (Oryza sativa L.) cultivars, which is a major area for lentil production in Bangladesh. The cultivation of this improved cultivar will play an important role for enhancing nutritional security by increasing lentil production in Bangladesh, Nepal, and eastern Indian states in South Asia.
