ABSTRACT
The experiment was conducted under glass house with three medium duration pigeonpea hybrids and varieties at Parbhani, Maharashtra during kharif 2012 to understand the process of seedling development under regular and limited irrigation conditions. Research revealed that as compared to varieties the hybrids produced longer radicle (17.92 ± 0.53 cm), greater leaf area (166.43 ± 3.14 dm2), more chlorophyll content (35.49 ± 0.53), high seedling dry weight (4.23 ± 0.11 g), root (1.87 ± 0.05 g)dry weight and greater seedling vigour index (4590.59 ± 180.4) underboth regular irrigation and limited irrigation conditions. This indicated that hybrids have potential to survive under drought conditions and produce more dry matter that can be associated with seed yield. The hybrids ICPH 2740, ICPH 3762 and variety Asha were found superior due to high seedling vigour index across the environments.
