Ten hybrids along with parents were evaluated for proline accumulation, before and after stress at panicle initiation and panicle emergence stages. Parents like 120A., CK. 60A. and 285 exhibited higher proline accumulation than check M 35-1. Proline accumulation increased due to stress. However, the range of heterosis was higher before stress treatment. Hybrids like 1202A x PD-3-1-1I, 1202AX285 and 1202AX168 accumulated significantly higher proline than check M 35-1 and revealed high heterosis.
