“…Hence it is obvious that number of tillers per plant should be one of the prime criteria in selecting superior plants for enhanced green fodder yield. The indirect effects of number of tillers per plant to green fodder yield was also found by Subbulakshmi et al [21,22].…”

Pearl millet is an ideal fodder crop having highly shiny, lush, palatable, nutrient- dense, excellent silage and biomass production potential and bestowed with various essential nutrients required for the livestock. The study material consists of 54 fodder pearl millet hybrids obtained through the hybridisation between 15 selected superior parents from ICRISAT gene-pool as well as gene pool of Department of Forage Crops, TNAU, Coimbatore. For the better understanding of the relationship between green fodder yield per plant, its contributing traits and various quality traits, genetic parameters such as genotypic and phenotypic correlation as well as path coefficients were analysed. Correlation studies revealed that out of all the seventeen biometric traits studied, all the traits are shown positive correlation with green fodder yield per plant whereas fifteen traits are found to have significant positive correlation with green fodder yield per plant. Ash content (rg =0.855), dry fodder yield per plant (rg =0.850), leaf-stem ratio (rg =0.710) have shown very strong significant positive correlation and plant height (rg =0.641), days to green fodder harvest (rg =0.630), stem girth (rg =0.616) and days to fifty per cent flowering (rg =0.606) have recorded with moderately strong significant positive correlation with green fodder yield per plant. Number of tillers per plant (0.859), internode length (0.574), ash content (0.421) and dry fodder yield per plant (0.372) revealed highly positive direct effects with green fodder yield per plant. Hence, selection for traits exhibiting positive association and direct effects for green fodder yield would help the breeder to enhance it further.

Thirty-seven pearl millet genotypes were evaluated for morphometric traits and disease incidence and severity during summer and kharif, 2022. Pooled ANOVA revealed significant variation were present in all genotypes across different season. Association studies identified high positive correlations between grain yield and traits such as single earhead weight, single ear head threshed weight, and test weight, with direct and indirect effects on grain yield through key characters. E2 (kharif – 2022) showed favourable conducive weather parameters for disease infection throughout the growing season compared to E1. The higher PCV relative to GCV for disease incidence underscores the environmental influence in disease resistance programs. Negative correlations between disease metrics and yield traits highlight blast disease’s detrimental effect on grain yield. Disease severity indirectly suggests environmental factors may enhance its impact. Disease incidence exhibited a direct negative impact on yield, supported by negative genotypic correlations. The line, PT 6679, exhibit both high yield and highly resistant to blast. Restorer lines (PT 6029, PT 6067, PT 6300, PT 6707, PT 7068) and B lines (ICMB 01666, ICMB 02777) showed promising yield attributes with high to moderate disease resistant for future breeding programs. In D2 analysis, five clusters revealed distinct genetic diversity with Clusters II and V indicating strong hybrid vigor, while Clusters IV (PT 6946, ICMB 06111) and V (ICMB 93111, ICMB 95444) excelled in disease resistance. Clusters I (PT 6029, PT 7068) and II (GMR 58) exhibited superior grain yield, particularly Cluster I, had potential restorer lines for future breeding. Clear differentiation between B and R lines underscored genetic distinctions in trait expression, validating the use of morphological data for assessing genetic diversity.
