Not Available A set of 100 inbred lines comprising of 50 normal and 50 quality protein maize (QPM) were analyzed for carotenoids composition such as total carotenoids, β-carotene, β-cryptoxanthin and zeaxanthin. Seven QPM HKI-3-4-8-6, HKI 34(1+2)-1, HKI 164-4(1-3), NP-06-07R-76-8, NP-06-07R-80-6, LQPM-42 and LQPM-40 and 9 normal lines (DML-288, DML-2, DML-112, DML-309, DML-45, BAJIM-08-27, BAJIM-13-1, HKI 1105 and HKI 1155) were found to possess significantly higher carotenoids as compared to the check (DMRQPM 103). Kernel colour intensity and total carotenoid contents showed highly significant positive correlation (r = 0.491 * *), whereas no significant correlation was observed between kernel colour and β-carotene (r = 0.014). Based on the carotenoids studied, a set of 16 lines HKI-3-4-8-6, HKI 34(1+2)-1, HKI 164-4(1-3), NP-06-07R-76-8, NP-06-07R-80-6, LQPM-42, LQPM-40, DML- 288, DML-2, DML-112, DML-309, DML-45, BAJIM-08-27, BAJIM-13-1, HKI 1105 and HKI 1155 was identified as promising lines which can effectively be utilized in the future breeding programmes towards the development of nutritionally improved maize (Zea mays L.).
