Abstract
Finger millet (Eleusine coracana G.) is one of the important small millet in India as well as in the Jharkhand state. It belongs to the family 'Gramineae with the chromosome number 2n=36. The present investigation was conducted in Dryland Research Farm of Birsa Agricultural University, Ranchi during Karif season of 1999. The variability, correlation and path coefficient analysis studies were made in a collection of fifty genotypes of finger millet for ten quantitative characters.
The analysis of variance revealed that there is the significant difference among all the lines for all the characters under study. Plant height, days to 50 per cent flowering and days to maturity showed wide range of variability.
The characters panicle length, number of fingers per panicle, effective tillers per plant, grain yield per panicle and grain yield per plant recorded the high phenotypic and genotypic coefficient of variation.
High heritability was observed for the characters panicle length, days to 50 per cent flowering, days to maturity, grain yield per panicle, 1000-grain weight and grain yield per plant. Moderate value of heritability observed for plant height, number of fingers and effective tillers per plant. These characters also had high or moderate value of genetic advance as percent of mean.
Correlation analysis revealed that grain yield per plant was strongly associated with panicle length, days to 50 percent flowering, days to maturity, grain yield per panicle and harvest index. There was negative correlation between number of fingers per panicle and grain yield per plant.
Path coefficient analysis, revealed that the characters plant height, days to 50 percent flowering, number of effective tiller per plant, grain yield per panicle, 1000-grain weight and harvest index effect directly towards the grain yield and the character panicle length and number of finger per panicle effect indirectly towards the grain yield.
The result obtained in the present investigation indicated that the characters panicle length, days to 50 percent flowering, days to maturity, effective tillers per plant, grain yield per panicle and 1000-grain weight are the yield contributing characters in finger millet and may be beneficial for further selection. These characters are correlated either significantly or positively with yield and also have high value of heritability and genetic advance as percent of mean.
