The study was aimed (1) To classify the germplasm lines based on scoring for various qualitative morphological traits, (2) to estimate the amount of genetic variability, heritability and expected genetic advance under selection, (3) to estimate intercharacter-correlation coefficients and direct and indirect effects of various component traits on grain yield, (4) to estimate the amount of protein content in grains. The observations were recorded on 17 quantitative characters and 16 qualitative characters. The analysis of variance revealed that there is highly significant difference among all 33 treatments for all the characters studied. Genotypic coefficient of variation was the major component of total variation however; PCV was invariably higher than GCV for the characters studied. Number of seeds per ear showed high PCV followed by ear weight, yield and number of productive tillers per plant while days to fifty per cent flowering recorded lowest PCV. Ear weight, thousand grain weight, protein content, days to maturity, days to fifty per cent flowering and yield showed high heritability and genetic advance. While, number of productive tillers per plant, leaf number per tiller, Length of flag leaf and finger length showed moderate heritability coupled with moderate genetic advance. Plant height, culm thickness, width of flag leaf, peduncle length, finger width and number of seeds per ear showed low heritability coupled with low genetic advance. Number of productive tillers per plant, leaf number per tiller, thousand grain weight and ear weight showed highly significant positive correlation with yield. Grain yield was found positively associated with days to fifty per cent flowering, plant height, culm thickness, peduncle length, finger number per ear, finger width and protein content. While days to fifty per cent flowering recorded highly significant positive correlation with days to maturity. Days to fifty per cent flowering, flag leaf width, number of productive tillers per plant, number of leaves, peduncle length and culm thickness showed positive direct effect on yield. Number of productive tillers per plant, leaf number per tiller, days to fifty per cent flowering, days to maturity, finger number per ear, thousand grain weight and ear weight showed positive indirect effect on yield through number of seeds per ear. In protein analysis it was found that the genotype GP-2011-79 found to contain high protein content than the checks. Similarly the genotype GP-2011-19 exhibited highest yield over the checks however the following genotypes GP-2011-294, GP-2011-366 and GP-2011-454 were also found high yielding which can be used as parental stocks in breeding programme. Therefore it can be concluded that selection for reduced plant height, more number of productive tillers per plant, increased ear weight, and more maturity duration would be in favour of achieving higher yield in finger millet.ennullThesis
