A field study was carried out involving three F2 and F3 population of barnyard millet crosses during 2016-2017. The high PCV and GCV values and high heritability were noticed in F2 population of three crosses for number of tillers, iron and zinc content, indicated the predominance of additive gene effects in their expression and would respond to selection effectively as they are least influenced by environment. In the F3 generation, the identified superior families in all the three crosses revealed that mean performance of yield and yield component characters progressively increased when compared to control [Co (Kv) 2] except for days to maturity and number of racemes (ACM 331 x ACM335, ACM 331 x ACM333) and single ear head weight (ACM 331 x ACM335). Three out of ten families of ACM 331 x MA10 cross exhibited superior mean performance than the control for most of the yield attributing and micronutrient traits. The coefficient of variation among the progenies of ACM 331 x MA10 cross was low indicated the settling down of homozygosity in F3 generation itself. These selected families are recommended for promoting to advanced generation for varietal development program with respect to high yield coupled with high iron and zinc content. The parent progeny correlation and regression between two generation (F2 and F3) of all the three crosses showed their lesser susceptible to environmental effect (i.e.) consistence performance.
