SUMMARY
The present investigation was conducted to assess the different early and late season advance lines of pearl millet for yield and its attributing traits. The grain yield varied between 0.57 kg (MPMH-17) to 2.03 Kg (MH2474), while dry fodder yield ranged between 1.18 kg (GHB 905) to 4.92 Kg (MH2474). The days to 50 % flowering was observed lowest in HHB-67-I (44 days) and highest in MH-2566 (55 days), whereas lowest number of days to maturity taken by MH-2557 & MH-2555(69 days) and highest by MH-2570 (79 days). The 1000-seed weight was found minimum in MH-2553 (5.67 g) and maximum in PB-1705 (12.60 g). The genotypes MH 2474, MH 2559, MH 2562, MH 2560 and PB 1705 were found superior for grain yield and dry fodder yield. The correlation analysis revealed that GYNP was highly significant and positively correlated DFY and PHNP, whereas DM, PH & 1000-SW showed positive and significant correlation. DFY showed highly significant and positive correlation with DF, DM PH and PHNP while PD and 1000-SW had significantly positive correlation with DFY. Moreover, cluster analysis categorized twenty seven lines into three clusters indicating that these lines share common ancestry with similar objective. Cluster III consisted of twelve lines, cluster II had eight and remaining seven lines were grouped into cluster I. The highest inter-cluster distance was found between cluster I and cluster III (85.45) while highest intra-cluster distance was observed in cluster I (55.97). Henceforth, the advanced lines yielded higher must be validated under different agro-climatic regions and further quality improvement should be strengthened.
