“…ese findings support previous studies on pearl millet at ICRISAT using a recombinant inbred line (RIL) population ICMB 841 × 863B which revealed that genotype × environment interactions were significant for grain yield, flowering time, plant height, and panicle length [40]. Similar reports show that genotype, environment, and their interaction effects influenced significant variation in pearl millet characteristics such as days to flowering, maturity, plant height, 1000-grain weight, grain yield, and seed micronutrients [41][42][43][44] and in finger millet [45,46] which corroborate the current findings.…”

Twenty-two open-pollinated varieties (OPVs) of pearl millet (Pennisetum glaucum) genotypes were tested in two locations for three seasons in Ghana to estimate the magnitude of genetic variability, heritability, and stability for grain yield and related traits and grain micronutrients among the varieties. General analysis of variance within and across locations and years revealed very highly significant variability ( p < 0.01 ) among the genotypes. The additive main effects and multiplicative interaction (AMMI) analyses revealed significant genotype × environment interaction (GEI) that influenced the relative ranking of genotypes across the environments. Genotypic variance ( σ 2 g ) contributed a greater proportion of the phenotypic variance (σ2p) for plant height (530.31) and grain Fe content (34.72). Broad-sense heritability ( h b s 2 ) varied widely from 24.82% for grain yield to 77.53% in days to flower. Phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all traits, indicating strong play of environment on trait expressions. 11 out of the 22 OPVs were stable for grain yield and micronutrients across environments for the three-year period and included GB 8735 and ICMV 221 Wbr and SOSAT-C88.

“…The differences among GCV and PCV were narrow suggesting the presence of effects for environments appeared in the genotypes x year's interaction. These results are in agreement with many authors among them: Sumathi et al (2010), Yadav et al (2001), Lakshmana et al (2009), Govindaraj et al (2011), Subi and Idris (2013) and Salih et al (2014).…”

The objective of this study was to estimate the genetic variability , heritability , genotypic and phenotypic coefficients of variations , genetic advance , range , genotypic and phenotypic variances and to study the genetic divergence by using multivariate analysis for yield and yield components in forty selected lines of pearl millet during 2012 and 2013 summer seasons at Sakha Agriculture Research Station. Analysis of variance manifested highly significant differences among all selected lines for all the studied traits. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV). Heritability in broad sense ranged from 11.12%for fresh leaf/ stem ratio to 86.87% for stem diameter. High estimates of bread sense heritability were found in all the studied traits, except dry matter and fresh leaf/stem ratio which, were medium and low, respectably. The environmental variance ranged from 13.13% for stem diameter to 88.88% for fresh leaf / stem ratio. The results also cleared that the genetic advance ranged from 0.91% for fresh leaf / stem ratio to 24.72% for total fresh forage yield. The results cleared that the ascendant order of the importance of evaluated traits were, the first factor accounted 41.78% (number of tillers, plant height, total dry forage yield and total fresh forage yield) while, the second factor accounted 59.62% (dry matter, stem diameter and fresh leaf /stem ratio) of the multivariate variance. The forty selected lines were grouped into eight clusters based on dissimilarity coefficients. Thus, the pearl millet breeder would use these selected lines from divergent cluster for hybridization in order to isolate useful recombinants in the segregating generations.

“…The ANOVA indicated significant variation among the genotypes tested and the GEI, showing that the multiplicative interaction of the genotypes and environments affected the performance of the test materials as also reported by Subi et al (2013). However, as noted by Crossa (1990), ANOVA does not explore the underlying structure within the GEI and thus other methods were adapted.…”

Pearl millet (Pennisetum glaucum (L.) R. Br.) is an important food security and income crop for households living in semi-arid zones in Uganda. However, the genotype by environment interaction, in addition to the several methods used for its assessment, complicates selection of varieties adapted to such semi-arid areas. The objective of this study, therefore, was to compare common methods used to assess stability and adaptability of improved genotypes. Seventy six genotypes were planted in four environments in an alpha experimental design with two replications. Results showed that genotype by environment interactions were significant at p<0.05 for grain yield, days to 50% flowering and 50% physiological maturity, percentage of productive tillers and panicle area. Results further showed inconsistency in ranking of genotypes between methods; although Cultivar Superiority, REML, Yield Stability Index and GGE biplot were consistently correlated and identified high yielding and stable genotypes.
