 ABSTRACT

Thirty-eight Pearl millet hybrids were evaluated in Randomized Block Design at Regional Agricultural Research Station, Palem. The objective of the study was to estimate the extent of genetic variability and association between yield and related traits. Analysis of variance revealed that there was highly significant (p<0.01) difference among the thirty-eight genotypes forthe traits viz., days to 50% flowering, days to maturity, plant height, panicle diameter, test weight, dry fodder yield and grain yield and significant difference (p<0.05) for panicle length. Grain yield ranged from 0.222 kg/plot (IHT 230) to 1.090 kg/plot (IHT 210). Highly significant grain yield was recorded in IHT 210 (1.090 kg/plot) followed by IHT 207 (0.782 kg/plot), IHT 212 (0.750 kg/plot) and IHT 232 (0.668 kg/plot) compared to local check (0.563 kg/plot). Low Phenotypic Coefficients of Variation and Genotypic Coefficients of Variation values were recorded in Days to 50% flowering and Days to maturity, medium in Plant height(cm), Panicle length(cm), Panicle diameter (cm), Test weight (g), Plant stand and high in Number of productive tillers/plant, Dry fodder yield (kg/plot) and Grain yield (kg/plot). Overall, Grain yield had high PCV, GCV, heritability and genetic advance as a percent of mean reveals is very important for selection criteria for crop improvement. Grain yield showed highly significant positive correlation with plant height followed by panicle diameter and panicle length which indicates true relationship between these traits and grain yield. Therefore, emphasis should be given for these characters of pearl millet improvement program.

Key words: Genetic variability, Heritability, Genetic advance, Correlation, Pearl millet.
