Establishing a rapid and effective method for screening salt tolerance in soybean

Chlorine (Cl) toxicity has been recognized as a constraint for soybean production. Although the use of a Cl-tolerant crop easily solves the problem, current screening methodologies for Cl tolerance are often ineffective because of inadequate means of detecting and measuring plant response to salinity. In order to facilitate the evaluation process and selection of Cl-tolerant genotypes, a study was conducted to develop a rapid and effective method for screening Cl tolerance in soybean. Seeds of five soybean cultivars, each representing either the includer or excluder genotype to salt stress, were grown in a greenhouse in two different growing media (potting mix or sandy loam) with four different concentrations of sodium chloride (NaCl) solutions. Visual symptoms of Cl toxicity were rated on a 1 to 6 scale (1 as healthy and 6 as dead), and the score was compared with relative shoot/ root dry weight and Cl concentration in shoot/root to corroborate the accuracy of the visual ratings. Reduced dry weight was associated with higher Cl concentrations in both root and shoot tissues. The optimal NaCl concentration for screening was determined as 120 mM NaCl since it effectively differentiated excluders from includers. There were negative, significant correlations between relative shoot dry weight and Cl concentration in shoot tissue (r = -0.91 p = 0.05), and Cl concentration in shoot was also significantly correlated with visual rating score (r = 0.79 p = 0.05). The presented methodology is simple, rapid, and effective for screening for salt tolerance in soybean

Comparison of instrumental methods for measuring seed hardness of food-grade soybean

Seed hardness is an important factor in determining soybean suitability for natto production. There is no established methodology for testing seed texture of soybeans. The objective of this study was to develop an efficient method by examining different instruments and seed parameters that could be potentially used for testing soybean seed hardness. Five food-grade soybean genotypes with different seed sizes were used to determine seed hardness and water-absorption capacity. Water absorption capacity was expressed by swell ratios for seed weight, seed dimension, and volume of water changes before and after soaking. Seed hardness test was conducted by a one-bite method using two food-texture analyzers: a TMS-2000 equipped with shear cell (SC) and a TA-XT2i equipped with either a single blade (SB), a 2-mm probe (PB), a 75-mm cylinder (CY), or a 16-probe pea rigs (PR). The results showed that hardness testing by CY with ten seeds (CV=0.14), SB with 5 seeds (CV=0.11), and SC with 30 g steamed seeds (CV=0.14) produced dependable and consistent results with low coefficient of variance. However, SC may not be practical for early plant selection in a breeding program due to a relatively large sample requirement. Seed size was negatively, whereas swell ratio by weight and volume was positively, correlated with seed hardness, and therefore, can be used as indirect selection indicators for seed hardness

Soybean seed yield and quality under an ultra-short-season production system

Drought is a major yield-limiting factor for soybean [Glycine max.] in the southern U.S.A. The ultra-short-season production system (USSPS), which uses maturity group (MG) 00 through I cultivars planted in April in Arkansas, may minimize severe yield reduction by drought since this system allows growers to harvest soybeans before severe drought occurs. The objective of this study was to evaluate yield potential and seed quality of Northern MG 00 through I soybean cultivars in a mid-South environment. Average yields of MG 00, 0 and I were 2954, 3585, and 3782 kg ha-1, respectively, under irrigated conditions. Average yield under dryland production was significantly lower than that under irrigated production. However, some cultivars yielded significantly higher than the Arkansas state average (1881 kg ha-1). Infection by seedborne fungi was minimal for all cultivars. Average germination rates under irrigated and non-irrigated production were 71, 71, and 68% for MG 00, 0, and I, respectively. There were large genotypic variations for seed yield and germination rate, suggesting cultivar selection is important for MG00 through I cultivars to be successful under the USSPS. These results show the potential of USSPS to produce a profitable crop in 79 to 100 d in the mid-South under both irrigated and dryland conditions
