In order to have wide variability in niger breeding, augmentation and evaluation of 1800 niger accessions, including indigenous and exotic collections, was conducted in rabi season at five diff erent locations of India, viz., Hyderabad (Telangana) in kharif and rabi seasons, Ranchi (Jharkhand), Akola (Maharashtra), Delhi (New Delhi) and Chinthapally, Araku (Andhra Pradesh). In all the locations, accessions IC0268292, IC0268293, IC0268294, IC0268295, IC 412911, IC411511, and IC305117 were found to be early for 50% flowering (30-40 days) and days to maturity (58-75 days) compared to the standard checks (JNS-9 and JNS-28). Seed yield in kharif season varied between 1.87 g/plant to 2.96 g/plant and in rabi season, it was 1.31 g/plant to 1.83 g/plant in the early accessions. These accessions can be further utilized in crosses with long-duration Ethiopian lines (which are late-types coupled with high yield) to select early and high yielding lines in the transgressive segregants.
