The present studies on seed vigour and storability of hybrids & its parental line in relation to laboratory parameters and field parameters were conducted during 2017-18, on maize (Zea mays L.) The materials for study constituted of two hybrids and its parental lines produced in rabi 2016-17, were collected and half portion of seed lots subjected to accelerated ageing for seven (07) days; and another half portion of seed lots were kept for natural ageing. Immediately after accelerated ageing, all seed lots were subjected to treatment with fungicide (T1- Thiram 75% WS @ 2g/ kg of seed), insecticide (T2- Imidacloropid 17.8% SL @ 2ml/ kg of seed) and combination of both (T3- Thiram 75% WS @ 2g/ kg of seed + Imidacloropid 17.8% SL @ 2ml/ kg of seed). There was significant reduction in performances of accelerated aged seed lots than natural aged seed lots. The effect of treatment T1 (Thiram 75% WS @ 2g/ kg of seed) and T3 (Thiram 75% WS @ 2g/ kg of seed + Imidacloropid 17.8% SL @ 2ml/ kg of seed) was found significant and positive for field emergence and field emergence index.
