“…Average protein was lower (421 and 425 g kg −1 ) in the Guelph and Ridgetown programs, respectively, while oil was higher (200 and 204 g kg −1 ), compared with Guelph historical cultivars with 428 g kg −1 protein and 191 g kg −1 oil. The ranges of oil and protein values across the germplasm groups were similar to those reported in germplasm surveys, such as Qin et al (2014) with an oil range of 142 to 228 g kg −1 across 127 Chinese cultivars, and Song et al (2016) with an oil range of 142 to 240 g kg −1 across 763 Chinese cultivars. These two studies reported 318 to 498 g kg −1 and 312 to 498 g kg −1 protein, respectively.…”

Improvement of agronomic and seed quality traits in soybean [Glycine max (L.) Merr.] occurs in breeding programs as a result of crossing elite soybean genotypes and selection of superior offspring in each cycle. The objective of this study was to evaluate changes in traits over 100 yr of selection in Ontario, Canada, in two soybean breeding programs at the University of Guelph: Guelph Campus (Maturity Group [MG] 0 and I) and Ridgetown Campus (MG II) programs. Fifty‐six Guelph cultivars (released between 1983 and 2016), 46 Ridgetown cultivars (released between 1987 and 2015), and 37 Guelph‐pedigree related historical cultivars (from 1913 to 1985) were grown in field trials over 3 yr (Guelph Campus) and 2 yr (Ridgetown Campus) at two locations per breeding program to measure 13 traits. Yield increased in the Guelph Campus cultivars by 17.1 kg ha−1 yr−1 and by 15.7 kg ha−1 yr−1 in the Ridgetown Campus cultivars, while yield per day of maturity per year of release significantly increased in elite cultivars. Protein in the Ridgetown Campus cultivars increased at 0.76 g kg−1 yr−1, whereas the Guelph Campus cultivars showed no trend. In Ridgetown Campus cultivars 100‐seed weight significantly increased at 0.1 g yr−1. Within the historical cultivars, 100‐seed weight was significantly correlated with both protein (r = 0.50) and oil (r = −0.42). Genotype × trait biplot analyses revealed differential patterns of trait relationships between the elite and historical cultivars. Oil and yield were associated within the Guelph Campus cultivars. The association of 100‐seed weight and protein was only found in the historical cultivars. Yield has increased in both breeding programs while seed traits have been altered over time.

“…Additionally, Arabidopsis thaliana ecotypes that originate in cooler, mountainous regions of the world have lower levels of very long‐chain fatty acids compared to ecotypes from warmer, lower altitudes (Millar & Kunst, ). Recently, it was shown that soybean seeds maturing in warmer climates generally had higher levels of total fatty acid content with a decreased levels of linolenic acid and increased levels of oleic acid which correlated with mean daily temperatures, but not to maturity group (Song et al., ). In this study, we examined the lipid composition in seeds which had not been acclimated during maturation (all grown under similar constant and normal growth conditions) to identify any potential markers within fatty acid composition that could be used to predict cold/chilling germination success.…”

Soybean has been considered a cold intolerant species; based largely upon seed germination and soil emergent evaluations. This study reports a distinct acquisition of cold tolerance, in seedlings, following short acclimation periods. Diversity in cold responses was assessed in 8 cultivars of Glycine max and 6 accessions of Glycine. soja.All varieties of soybean significantly increased in freezing tolerance following acclimation. This study indicates soybean seedlings are indeed capable of sensing cold and acquiring cold tolerance. Germination rates after cold imbibition were negatively correlated with maturity group, but positively correlated with cold acclimation potential in G. soja. Seed fatty acid composition was varied between the species, with G. soja accessions containing about 2-times more linolenic acid (18:3) than G. max.Furthermore, high levels of linoleic acid (18:2) in seeds were positively correlated with germination rates following cold imbibition in G. soja only. We suggest that domestication has not impacted the overall ability of soybean to cold acclimate at the seedling stage and that there is some variation within the domesticated species for ability to cold acclimate. Thus, this brief comparative study reduces the enthusiasm for the "wild" species as an additional source of genetic diversity for cold tolerance.

BACKGROUND Lunasin is a novel therapeutic peptide that was initially isolated from soybean. In this study, we quantified the variations in lunasin content in a total of 413 soybean samples that were collected from four major regions in China and harvested in 2014 and 2015 to reveal the regional distribution of soybean lunasin content in China and the effects of climate factors. RESULTS The results showed that the cultivar Changmidou 30 collected from Jilin province and harvested in 2015 had the highest lunasin content (3.25 g kg−1 dry seeds). The data from both 2014 and 2015 showed that the lunasin content in soybean collected from northern China was significantly higher (P < 0.05) than that from south China. There was a positive correlation (P < 0.01) between lunasin content and hours of sunshine (HS) as well as diurnal temperature range (DTR); however, there was a negative correlation (P < 0.01) between lunasin content and rainfall (RF). In addition, combined analysis of data from 2014 and 2015 demonstrated that DTR was the dominant factor that affected lunasin content with a direct path‐coefficient of 0.301. CONCLUSIONS These results were anticipated to contribute to guiding the cultivation of soybean with high lunasin content. © 2018 Society of Chemical Industry
