Oct 25, 2024 · Are more soybeans per pod better than pods with fewer but bigger beans? Agronomist Steve Gauck explores this conundrum.

The number of four-seed pods is one of the most important agronomic traits affected by gene and environment that can potentially improve soybean (Glycine max) yield. However, the gene regulatory network that affects the ratio of four-seed pod (the ...

Mar 1, 2024 · Guo et al. (2021) proposed an improved YOLOv4-based model to classify soybean pod as empty pods, one-seed pods, two-seed pods, three-seed pods, four-seed pods and five-seed pods, six types of soybean pods. Whereas, Guo et al. focus on classification and neglect instance segmentation.

Of the two, seed number has the greatest impact on final soybean yield. Seed number is a function of the plants per acre, pods per plant, and seeds per pod. The maximum number of seeds per pod, or prevalence of 4-bean pods, is largely determined by genetics.

Jan 17, 2023 · According to the data published on the SoyBase, 425 QTLs related to soybean four-seed pods have been reported to date. In this study, 12 QTLs detected in a single year and 5 QTLs repeatedly detected in two years or more were mapped by PoFSP data and BLUE value in CSSLs from 2016 to 2018.

Jun 15, 2020 · Here, linkage analysis combined with genome-wide association study (GWAS) was used to identify 20 pod number-related traits in four-way recombinant inbred lines (FW-RILs) derived from crosses between the four soybean varieties (Kenfeng 14 × Kenfeng 15) × (Heinong 48 × Kenfeng 19).

Dec 29, 2015 · Seed number per pod is an important component of yield traits in soybean (Glycine max L.). In 2010, we identified a natural mutant with an increased number of four-seed pods from a soybean variety named 'Jinong 18' (JN18). Subsequent observations indicated that the trait was stably inherited.

Sep 1, 2021 · These findings provide basic insights into the understanding of the underlying gene regulatory network affected by specific environment and lay the foundation for identifying the targets that affect the ratio of four-seed pod in soybean.

At R4, the plant reaches the full pod stage, pod growth is rapid and seed development begins. This is the most crucial stage for seed yield. In hot, dry conditions, consider irrigation if available.

The system of soybean growth stages divides plant development into vegetative (V) and reproductive (R) stages. The vegetative stages are numbered according to how many fully-developed trifoliate leaves are present. The reproductive (R) stages begin at flowering and include pod development, seed development, and plant maturation.
