Resistance to Fusarium Solani F. Sp. Glycines, the Causal Organism of Sudden Death Syndrome of Soybean
… to FSG in PI 522.211 A may be quantitative. The broad-sense heritability estimate for resistance was 0.32.

Genetic analysis of Cannabis flowering traits in differential environments
… showed both low phenotypic variability and low broad-sense heritability. Since low broad-sense heritability commonly indicates that the environment plays a dominant role in trait development, the absence of a significant influence of the environment on these traits reflect they are under genetic …

Assessment of Hard Red Spring Wheat Germplasm for Germination in Sub-Optimal Temperatures
… were found to have the lowest level of CTGT. Broad sense heritability of CTGT on an entry mean basis was estimated to be 0.73 across the temperatures of 5-11 °C. This suggests that spring wheat breeders should be able to manipulate CTGT without great difficulty.</p>

The development of the curve of spee in Australian twins.
… curve of Spee a classical twin model was used, broad sense heritability estimates were derived to quantify the extent of genetic contribution to the observed phenotypic variation. The result indicated that the greatest change in the depth of the curve of Spee occurred between mixed and permanent …

Phenomics enabled genetic dissection of complex traits in wheat breeding
… measures to visual estimates and superior broad-sense heritability demonstrate these approaches are amenable for reproducible assessment of complex plant traits in large breeding nurseries. Using these validated high-throughput measurements, we applied genome-wide association and prediction …

Grain hardness and slow dry matter disappearance rate in barley
… and study environmental effects, inheritance and heritability of hardness.To study grain hardness and genetic and environmental effects on DMDR, two genotypes grown at multiple locations in 2004 were analyzed for Single Kernel Characterization System (SKCS) hardness, by scanning electron …

A genetic study of resistance to kernel infection by Aspergillus flavus in maize (Zea mays L.)
… effects were highly significant. Broad-sense heritability for PKI estimated from variance components was 73.8%. A North Carolina Design-II analysis of 12 crosses was used to estimate additive and dominance genetic variances. Narrow-sense heritability and the average degree of …

Evaluation and breeding of Hilaria belangeri for turfgrass use.
… (uncut) plots exhibited low vigor and color. Broad-sense (h²(b)) and narrow-sense (h²(n)) heritability estimates were computed for measured and rated characters on clones and their open-pollination progeny grown at Safford (S) and Tucson (T), AZ. Estimates of h²(b) of measured characters were: …

Genetic Analysis of the Resistance of Soybean Genotypes to Sclerotinia Sclerotiorum
… stem rot resistance into elite germplasm. The broad-sense heritability estimate was 0.37 for disease severity across environments in the A2506 by S19--90 population. Although lower disease severity was associated with short plant height and reduced canopy closure at flowering, which may be …

Genetics underlying flaking grit yield from dry milled maize grain
… performance in the future. The survey used a broad-based set of inbreds that represent parentage of heterotic subgroups utilized in current commercial maize hybrids. The 12 inbreds were crossed in a diallel design without reciprocals to create 66 test hybrids which were evaluated for …

Genetic variation of heat tolerance and correlation with other agronomic traits in a maize (Zea mays L.) recombinant inbred line population
… inbred line population, and to estimate the heritability of those traits. A total of 179 maize recombinant inbred lines from B76 x B106 were evaluated at Pecos, TX, in 2001, at Texas Tech University (TTU) experimental farm in 2002, and at TAMU Lubbock center in 2001 and 2002. Significant …

Genetics and genomics studies of rice disease resistance and development of alternative disease management methods for bacterial panicle blight and sheath blight
… to suppress BPB and SB were also studied. Broad-sense heritability and correlations were calculated for the traits, BPB and SB disease ratings, days to heading, and plant height, with recombinant inbred lines generated from a cross between Trenasse and Jupiter in replicated trials for two …

QTL mapping of Phytophthora root rot resistance and aphid resistance in soybean
… a modified rice grain inoculation method. The heritability of the PRR resistance ranged from 83% to 94%. A major locus contributing 50% to 76% of the phenotypic variation was detected within a 3 cM interval in the Rps1 region. Based on the specific responses to the tested races, this locus was …

Agronomic and marker-assisted breeding strategies for improving nitrogen use efficiency in maize
… plant ha-1, at 50 cm row spacing) combined high broad-sense heritability and yield performance. Therefore, breeding programs evaluating maize genotypes under intensive agronomic management conditions can obtain greater genetic gain. Future maize yield increases will rely on genotypes that combine …

The influence of cultivar and environment on the relationship between flour protein content and grain yield in wheat
… for protein content was negligible. The broad sense heritability for grain yield was low (ranging from 12.0 to 32.7%). However, the heritabilty for protein content was high (ranging from 75.7 to 81.3%). The broad sense heritabilities for grain N Yield, N uptake and NHI were relatively low …
