Abstract:

An investigation was carried out to assess the character association in forty germplasm and two F2 population for biometrical and nutritional traits in barnyard millet during Rabi, 2014 and Rabi, 2015 respectively. Both F2 population exhibited wide variation and comparatively better than their respective parental genotypes for yield related traits and micronutrient content. From association analysis, there was alteration/shift in the association of few character pairs in germplasm and two segregating population, meaning that the traits might be unlinked due to weak or non-significant association or variability level. Path analysis in germplasm revealed that stem girth, single ear head weight, ear head breadth, number of racemes, zinc content, number of productive tillers, flag leaf length, thousand grain weight and plant height had high positive direct effect on grain yield. It is surprising to note that the association between Fe and Zn content in grains was positive but non-significant association with grain yield would create the possibility of selecting the plant which high micronutrient content with moderate yield or hybridization followed by selection for enhancement of iron and zinc content in barnyard millet.
