The Seed–Seedling Transition in Commercial Soybean Cultivars with the Presence of Greenish Seeds in the Sample: A Perspective from Classical Genetic Parameters

Abstract

Chlorophyll retention reduces the quality of soybean grain and seeds, but little is known about the relationship between this anomaly and the seed–seedling transition or classical genetic breeding. Taking this into account, we provide a new perspective about how greenish seeds are associated with genetic material. For that, we used seed–seedling transition measurements of nine commercial cultivars cultivated by different seed farmers. Our findings demonstrated that: (i) The anomaly of greening in soybean seeds seems to be more expressed as a function of thermal variation than rainfall; (ii) There are commercial cultivars with distinct sensitivity to the greening phenotype, indicating potential for classical breeding for the species; (iii) The seed–seedling transition is significantly modified by the presence of greenish seeds, and the diagnosis of their presence can be anticipated by the analysis of embryo protrusion.

Soybean Seed Coat Cracks and Green Seeds—Predisposing Conditions, Identification and Management

“…According to Ajala-Luccas et al [42], (i) the soybean green seed anomaly seems to be more expressed as a function of thermal variation than water variation, (ii) there are commercial soybean varieties with a distinct sensitivity to the incidence of green seeds, indicating the potential for classical breeding, (iii) the seedling formation is significantly modified by the occurrence of green seeds, and (iv) the analysis of embryo protrusion can anticipate the diagnosis of a higher proportion of green seeds.…”
