Merr.] (Reg. no. GP‐442, PI 696388), is an F5–derived early maturity group (MG) VI germplasm jointly released by the USDA–ARS and North Carolina Agricultural Research Service in January 2021. USDA‐N6005 is a genetically diverse germplasm with 25% of its pedigree from Japanese cultivar Tamahikari and has high yield potential coupled with elevated seed and meal protein content. USDA‐N6005 is the first MG VI release derived from Tamahikari. In the USDA Uniform Tests–Southern States during 2017–2018, USDA‐N6005 yielded 102, 103, and 102% of the check cultivars NC‐Dunphy, NC‐Dilday, and NC‐Roy, respectively. It had significantly better lodging resistance (1.5) than NC‐Roy and NC‐Dilday (2.6 and 2.5, respectively). The seed protein content on a dry basis of USDA‐N6005 (424 g kg–1) was significantly higher than that of NC‐Dunphy and NC‐Dilday (392 and 383 g kg–1, respectively). The estimated meal protein content (49.0%) of USDA‐N6005 was significantly higher than that of NC‐Dunphy and NC‐Dilday (46.2 and 45.5%, respectively). Across the five environments of the 2016 USDA Preliminary Tests–Southern States, USDA‐N6005 yielded 100 and 102% of check cultivars AG6534 and NC‐Roy, respectively. This release should help to reverse the declining trend in genetic diversity and seed protein of U.S. soybean cultivars without negative impact on seed yield.}, number={2}, journal={JOURNAL OF PLANT REGISTRATIONS}, author={Mian, M.

GP‐438, PI 692263) is a conventional late maturity group VII soybean [Glycine max (L.) Merr.] germplasm with good yield potential, elevated seed protein content, and 25% exotic pedigree from Japanese cultivar Tamahikari (PI 423897). USDA‐N7004 was jointly released as a non‐GM germplasm by the USDA‐ARS and the North Carolina Agricultural Research Service in September 2019. USDA‐N7004, experimental name N10‐711, was derived from a cross of USDA‐ARS breeding lines NTCPR01‐163 (‘Dillon’ × Tamahikari) and N03‐832. Across 27 environments of the USDA Uniform Soybean Tests‐Southern States (Uniform Tests), USDA‐N7004 yielded 97 and 94% of elite checks ‘N7003CN’ and ‘NC‐Wilder’, respectively. Over 20 environments of United Soybean Board Southern Diversity Yield Trials (Diversity Trials), USDA‐N7004 yielded 98 and 94% of the same two checks, respectively. In the Uniform Tests, seed protein content of USDA‐N7004 (421 g kg−1) was significantly higher than N7003CN and NC‐Wilder on a zero‐moisture basis (405 and 399 g kg−1, respectively). The meal protein content of USDA‐N7004 (49%) was significantly higher than N7003CN or NC‐Wilder (47%) in the Uniform Tests as well as in the Diversity Trials. USDA‐N7004 should be a useful parent in breeding programs aimed at broadening the genetic base of soybean along with improving seed protein and seed yield.}, number={3}, journal={JOURNAL OF PLANT REGISTRATIONS}, author={McNeece, Brant T. and Bagherzadi, Laleh and Carter, Thomas E., Jr. and Mian, M.

Merr.] genotype PI 471938 expresses a slow-wilting phenotype in the field, and the progeny of this genotype have shown to have high yield under water deficit conditions. However, the physiological basis for the slow-wilting trait in PI 471938 remains unclear, and failure to understand the causal mechanism may limit future breeding efforts. This study investigated three primary hypotheses for trait expression that could explain slow-wilting trait in PI 471938: (1) a low osmotic potential in the leaves allowing greater water retention, (2) high elastic modulus of leaves resulting in delayed development of wilting, and (3) high hydraulic conductance allowing rapid water redistribution in the plants. Experiments included three other soybean genotypes as references for the results obtained with PI 471938. Surprisingly, the results for PI 471938 did not prove to be unique as compared to the other three tested genotypes for any of the three hypotheses. These negative results indicate that a hypothesis outside the usual candidates describing plant water transport, possibly anatomical features related to specific water transport properties, is required to explain slow-wilting in PI 471938.}, number={3}, journal={JOURNAL OF CROP IMPROVEMENT}, author={Bagherzadi, Laleh and Sinclair, Thomas R. and Zwieniecki, Maciej and Secchi, Francesca and Hoffmann, William and Carter, Thomas E. and Rufty, Thomas W.}, year={2017}, pages={400–417} }

Experimental observations were consistent with these limitations. Combined, these results indicate a need for caution in high-throughput screening and phenotyping. Pot experiments are a mainstay in many plant studies, including the current emphasis on developing high-throughput, phenotyping systems. Pot studies can be vulnerable to decreased physiological activity of the plants particularly when pot volume is small, i.e., "pot binding". It is necessary to understand the conditions under which pot binding may exist to avoid the confounding influence of pot binding in interpreting experimental results. In this paper, a derivation is offered that gives well-defined conditions for the occurrence of pot binding based on restricted water availability. These results showed that not only are pot volume and plant size important variables, but the potting media is critical. Artificial potting mixtures used in many studies, including many high-throughput phenotyping systems, are particularly susceptible to the confounding influences of pot binding. Experimental studies for several crop species are presented that clearly show the existence of thresholds of plant leaf area at which various pot sizes and potting media result in the induction of pot binding even though there may be no immediate, visual plant symptoms. The derivation and experimental results showed that pot binding can readily occur in plant experiments if care is not given to have sufficiently large pots, suitable potting media, and maintenance of pot water status. Clear guidelines are provided for avoiding the confounding effects of water-limited pot binding in studying plant phenotype.}, number={4}, journal={PLANTA}, author={Sinclair, Thomas R. and Manandhar, Anju and Shekoofa, Avat and Rosas-Anderson, Pablo and Bagherzadi, Laleh and Schoppach, Remy and Sadok, Walid and Rufty, Thomas W.}, year={2017}, month={Apr}, pages={729–735} }
