A study was conducted to determine the immediate effects of mechanical damage to soybean seed as influenced by a combine harvester applying different levels of threshing effort on pods and seed at different levels of moisture content. Four rows were harvested at a time, and the yield was 34 bushels per acre. A rasp bar cylinder type harvesting combine was used to harvest the seed at 16.85, 13.05 and 1.65% moisture content, applying Threshing Indices of 70, 87, 108 and 130. Visible effects of damage, evaluated as percentage of split seed, cracked coated seed, visibly uncracked seed and seed size, revealed that the interaction of seed moisture and Threshing Index was of significant importance in determining the degree of injury to seed at harvesting. For any level of one of these two factors, the extent of injury was dependent upon the level of the other factor, except for cracking of the seed coat, for which the interaction failed to be significant. Decreased levels of seed moisture content and increased cracking of seed coats, and a decrease in the proportion of visibly uncracked seed. Combine harvested seed tended to be smaller than hand harvested. Physiological responses of the combine harvested seed were evaluated by the standard germination test, accelerated aging test, storage under adverse conditions, and soil emergence. Seed harvested at 16.85% moisture produced lower germination percentages and lower vigor ratings than did seed harvested at 13.05 and 11.65% moisture. Increased Threshing Index caused a decrease ...

Embrapa has led breeding programs for irrigated and upland rice (Oryza sativa L.) since 1977, generating a large amount of pedigree and phenotypic data. However, there were no systematic standards for data recording nor long-term data preservation and reuse strategies. With the new aim of making data reuse practical, we recovered all data available and structured it into the Embrapa Rice Breeding Dataset (ERBD). In its current version, the ERBD includes 20,504 crosses involving 9,974 parents, the pedigrees of most of the 4,532 inbred lines that took part in advanced field trials, and phenotypic data from 2,711 field trials (1,118 irrigated, 1,593 upland trials), representing 226,458 field plots. Those trials were conducted over 38 years (1982-2019), in 247 locations, in latitudes ranging from 3°N to 33°S. Phenotypic traits included grain yield, days to flowering, plant height, canopy lodging, and five important fungal diseases: leaf blast, panicle blast, brown spot, leaf scald, and grain discoloration. The total number of data points surpasses 1.27 million. Descriptive statistics were computed over the dataset, split by cropping systems (irrigated or upland). The mean heritability of grain yield was high for both systems, at around .7, whereas the mean coefficient of variation was 13.9% for irrigated trials and 18.7% for upland trials. The ERBD offers the possibility of conducting studies on different aspects of rice breeding and genetics, including genetic gain, G×E analysis, genome-wide association studies and genomic prediction.
