ABSTRACT
Germination, emergence and establishment are critical phases to the growth cycle of plant as it determines the density of the crop stand obtained. On the basis of standard germination values field emergence can't be evaluated directly. Seed vigour can be evaluated in order to evaluate field performance of any crop. The experimental materials consisted of nine maize inbred lines, one tester and nine single cross hybrids and one check (Indra 17). Results showed that larger and medium size seeds had higher germination percentage and vigour than that of small size seeds. Maximum seedling length, seedling dry weight, vigour index I, relative growth index, mean daily germination, mean germination time, peak value and coefficient of germination was observed in large and medium seeds, which determine that large seeded hybrids are more promising hybrids than other. The highest physiological performance was found in terms of seed germination and vigour quality parameter in single cross hybrids C2, C8 & C9.
Key words :
Coefficient of germination, Maize hybrids, Mean germination time, Peak value, Relative growth index, Seed vigour.
