Discrimination of Root System Architectural Traits, Morphometric Traits and Identification of Potential Genotypes in Response to Drought and Irrigated Conditions in Pearl Millet (Pennisetum glaucum (L.) R. Br.)

Aims: To identify the potential genotypes and important traits for drought tolerance based on root system architectural morphometric that can be used as a selection criteria in future crop improvement programs.
 Study Design: Completely randomized design Randomized block with two replications traits.
 Place Duration of Study: Department Millets, Tamil Nadu Agricultural University, Coimbatore during Summer 2022.
 Methodology: The 33 elite were raised polybags factors, one is genotype other treatment observing completely design. Also these field treatments, irrigated at early stage Results: Based traits, significant network perimeter, surface area, length volume. Under condition, high phenotypic coefficient variation genotypic observed single plant yield, heritability genetic advance days to 50 per cent flowering, height, leaf blade length, spike 1000 seed weight yield. Correlation study revealed all characters except number tillers flowering had positive correlation Path analysis showed direct effect yield.
 Conclusion: identified volume, tolerant Nattu cumbu, ICMB 10444, 86M38 PT 6752.
