Effects of panicle removal and nitrogen on yield of grain sorghum
… removal increased the number of tillers and kernel weight but decreased yield (by reducing kernel number) in Segaolane and NK 2660. The kernel weight in Korwane did not respond to panicle treatments, but grain yield was reduced by panicle removal. In all cultivars, photosynthesis was reduced …

Genetic and agronomic approaches for improving nitrogen use and maize productivity
… genetic backgrounds and environments. Individual kernel weight is a largely untapped resource for improving maize yields, and several chapters of this dissertation highlight its importance. Responses of kernel number and kernel weight to increased N supply were negatively correlated, and kernel …

Effect of Allelic Variation in Rht Loci on Plant Height and Grain Yield of Soft Red Winter Wheat (Triticum aestivum L.)
… was due in part to significantly higher 1000 kernel weight and kernel weight spike-1, which resulted in higher kernel weight per spike. In addition, seven potential QTL associated with most of the traits measured were identified using a bi-parental approach. In conclusion, future breeding work …

Association Mapping for Elemental Concentration Resulting from Vegetative Stage Soil Waterlogging Stress in Wheat (Triticum aestivum L.)
… combined effect of decreases in total biomass, kernel-weight per spike and spikes m-2. Strong negative correlations were observed between GY and accumulation of aluminum, iron and sodium, indicating likely elemental toxicity. Cultivars ‘Jamestown’ and ‘USG3555’ were found to be the most tolerant …

Evaluation of wheat(triticum aestivum l.)gentypes for nitrogen and water use efficiency
… above ground biomass, plant height, thousand kernel weight, grains per ear, harvest index, spikes per ear, days to 50 % flowering and leaf rolling were assessed and analysed. Correlation and stepwise multiple regression analyses were done to study the parameter relationship. The results …

Genotype and Nitrogen fertilizer influence on Grain yield and protein content of wheat(Triticum aestivum L.)
… . Grain yield and yield parameters (thousand-kernel weight , grain number per head, number of heads per square meter and harvest index) were measured. Quality parameters were protein content percent and mixograph development time. Grin yield significantly (P<_0.05) increased with Application …

Within-row spacing effect on individual corn plant yield
… plant’s individual space in the row and grain weight per plant (r = 0.0007 p = 0.60). In contrast, in 2012 there was a significant correlation (r = 0.12 p < 0.0001), and per-plant grain weight increased 2.5 g for each additional cm of space along the row. Plant spacing affected neither kernel …

Genetic Variability, Correlations and Selection Response for Kernel Traits in Two Modified Endosperm Opaque-2 Maize Populations
… and responses to S(,1) family selection for kernel traits in two modified endosperm o(,2) maize populations (D.O. mod. o(,2) and El. S.C. mod. o(,2)). In 1982, 120 S(,1) families were evaluated for percent modification, kernel density, 100 kernel weight, percent protein, percent zein, percent …

Dissection of Soil Waterlogging Tolerance in Soft Red Winter Wheat using Genomic Approaches
… coupled plasma spectroscopy. Yield components kernel number per spike (KNPS), kernel weight per spike (KWS) and thousand kernel weight (TKW) were measured at plant maturity. Negative correlations between TKW and KWS with aluminum and iron concentrations indicated the impact of elemental …
