ABSTRACT

An investigation was carried out separately for each year to examine the relationship of cold
stress effect on grain yield and yield component characters respective to the parents and progenies
of a cold sensitive plant. For the 3 consecutive years the seeds were sown in the month of June
and the plants were allowed to expose in clod stress condition at maturity. Influence of
temperature effect on days to flowering and maturity was determined by correlation analysis.
Unexplained variability in first year registered high for yield (average weight of head). Number
of seeds per spikelet had significant positive contribution on determining the yield of finger
millet during second and third year. The correlation study indicated that sensitivity of cultivars
to different temperature might be responsible to produce unexplained variability in the population
through the appearance of new combinations, disappearance and re-appearance of some old
combinations of characters
