 ABSTRACT

Studying the genotypic variations in root and shoot growth is crucial for developing stress-resilient genotypes and several studies have reported significant association between root traits and crop performance under moisture stress. Ten selected maize hybrids, their parents and checks were grown in polybags and were subjected to grow at two soil moisture levels (100% and 50% field capacity) after 10 days of sowing to till 60 days. The growth parameters viz., plant height, leaf number, leaf area, shoot dry weight,  root length, root volume and root dry weight  were recorded after 60 DAS. Significant variation for different parameters among genotypes and moisture levels were observed. Genotypes showed varying degree of changes with moisture levels.  DMIL 516 X DMIL 230, DMIL 553 X DMIL 447 and CML 425 X DMIL 516 these hybrids and their parents DMIL 516 and DMIL 553 found to be acceptable genotypes for drought based on the root and shoot growth.
