Yield variation and associated changes in relationship of component characters of a cold sensitive finger millet genotype in subsequent generation

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.
