Evaluation of pop sorghum germplasm for productivity and popping traits

Abstract

The experimental material consisting of 44 genotypes involving 39 pop-sorghum germplasm lines and five checksincluding special variety for popping KMJ-1 was evaluated for popping and productivity traits. During Rabi 2019 in areplicated trial at RARS, Vijayapura. Significant treatment variances were observed for traits days to 50% flowering, plantheight and panicle length. The grain weight per plant, panicle weight, grain number per plant, popping expansion ratio and flakesize recorded high estimates of phenotypic coefficient of variation (PCV). Moderate estimates of PCV for panicle length,hundred grain weight and popping yield and low estimates for days to 50% flowering and plant height were recorded.Promising genotypes identified for popping traits were SPGT-2, SPGT-12 and SLR 211-142; for both popping and yieldtraits were GRPM-362-28 and GRPM362-352, and for yield traits were GRPM362-5, GRPM36217 and SPGT-1.
