Description 918-924
maturing cultivars is one of the important breeding goals in barnyard millet, which can fit well when main crops fail, or
during the late onset of monsoon. Thus, this study was carried out to test the phenotypic diversity, character association and
path coefficients, and stability of early maturing barnyard millet accessions. The MDU 1, a slightly late-maturing (95 days)
cultivar, was used to identify early maturing accessions than the control with a considerably higher yield. Diversity as
revealed by D2 analysis indicated that the trait grain yield had contributed the most towards the diversity followed by the
traits such as thousand-grain weight and fodder yield per plant. The accessions IEc 350 and IEc 356 showed the highest
fodder yield and grain yield per plant, and higher per day productivity than the control, MDU 1. Genotypic correlations
revealed a significantly positive correlation of the grain yield with most traits investigated including days to maturity and
fodder yield, and the trait fodder yield per plant showed a highly positive indirect effect on grain yield. Hence, these traits
could be considered during the selection process for improving grain yield. Stability analysis identified two accessions, IEc
350 and IEc 356, and the MDU 1, as the stable high-yielding accessions. Hence, these high-yielding stable accessions can
efficiently be used in barnyard millet improvement for developing early maturing varieties.
