“…Its indirect effect via thousand kernel weight was positive therefore, the positive correlation coefficient with grain yield was mainly due to its direct and indirect effect. The direct positive effect of plant height to grain yield is in accordance with Kalpande et al (2014) and Silva et al (2017) Kernel length revealed small positive direct effect to grain yield and also showed positive indirect effect through thousand kernel weight and hectoliter weight to grain yield. The causes of the positive association of kernel length with yield were mainly due to its positive direct effect and indirect effects through thousand kernel weight and hectoliter weight.…”

Sorghum is a drought tolerant C 4 tropical crop with wide diversity grown for food, feed and beverages. There is a growing demand for food and malt type sorghum varieties due to the low supply of mat barley, and climate resilient and gluten free nature of the crop. This study was initiated to estimate the associations among traits and the relative importance of traits in influencing grain yield and malting quality of sorghum genotypes. The experiment was conducted at Fachagama in Mhoni ARC, Northern Ethiopia in 2016/2017 using αlattice design in two replications using supplementary irrigation. Data were collected on agronomic traits, and a selection of 300 g pure seeds were malted (18 hr steeping, 72 hr in 28°C germinated and 24 hr in 50°C dried) for malt quality analysis. Positive and significant correlations with grain yield of TKW (0.766, 0.715), KL (0.671, 0.644), KW (0.524, 0.491) HLW (0.532, 0.504, FHWE (0.257, 0.241) and DP (0.275, 0.271) at both phenotypic and genotypic level was found respectively. TKW exerted high positive genotypic (0.334) and phenotypic (0.287) direct effect and even higher indirect effect on grain yield, which indicated that attention should be given to TKW primarily for direct and indirect selection for yield improvement. Thousand kernel weight and fine grind hot water extract showed a significant positive correlation with diastatic power at genotypic level and increment in these traits results in advancement of diastatic power.

In Brazil, the common bean crop has representative agricultural exploitation, not only because of its production economic value, but also because there is a large cultivation area. This research aimed to investigate the direct and indirect relationship of morphological components on grain yield in common bean plants. This study was carried out in a Quartzarenic Neosol in the municipality of Cassilândia, Mato Grosso do Sul State, Brazil, in the agricultural year of 2016/2017. The evaluated traits were: grains yield (GY) with its primary components; mass of one hundred grains (HG); number of grains per plant (GP); number of grains per pod (GPP); dry weight of aerial parts (DWA); number of pod per plant (PP); plant dry mass (DM); plant high (PH); and stem diameter (SD). Initially, the Pearson's correlation among these traits was estimated and the correlation network was used to graphically express the obtained results. Analysis of these data through the statistical techniques of multicollinearity diagnosis followed by path analysis enabled to verify that the number of pod per plant, the mass of one hundred grains, and the number of grains per plant, among the primary components of grain yield, are the traits of greater potential to select and identify superior genotypes for grain productivity yield, and that dry matter and stem diameter traits showed a negative correlation with grain yield in common bean grains.

“…Previous studies also reported positive correlations of productive tillers, panicle length, panicle girth, days to maturity to grain yield in pearl millet (Govindaraj et al, 2013;Sattler et al, 2018). Similarly, genotypes with tall height, high panicle weight and panicle harvest index were indicated to likely increase grain yield in sorghum (Da Silva et al, 2017). Although DFL was positively correlated with FYD, its correlation with grain yield was negative, implying very late flowering genotypes are not preferred in breeding for dual-purpose millet varieties.…”

Pearl millet (Pennisetum glaucum (L.) R. Br.) is a cereal crop vital for food security in West and Central Africa. Its byproducts also serve as fodder for livestock, especially during dry seasons. The objective of this study was to evaluate selected genotypes from West African pearl millet breeding programmes, for dual-purpose (grain and fodder) and elucidate prospects for future breeding. A total of 83 open-pollinated varieties (OPVs), five composites, six landraces, one synthetic and five hybrids were evaluated at 14 environments in Burkina Faso, Mali, Niger and Senegal during the rainy seasons of 2015 and 2016. Combined analysis of data revealed significant differences among genotypes and prevalence of high genotype-by-environment interaction effects. Two stability analyses models consistently indicated that genotypes 10 (SMILBF10), 14 (SMILBF14) and 39 (SMILML5) were widely adaptable across the region. Plant height, panicle length and panicle yield showed significant positive correlations with grain yield; while days to flowering was negatively correlated. Positive correlation between grain and fodder yields indicate possibility for simultaneous improvement involving the two important traits. This result suggests that germplasm exchange and regionally integrated breeding programmes are important for the identification of widely adapted dual-purpose varieties of pearl millet, particularly in West African drylands.
