Monthly summary for 2025-09 (bcgov/nr-spar): Focused on stabilizing data handling in display paths and advancing breeding value calculations with Seedlot Management (SMP) integration. Delivered a bug fix for Moisture Content (MCC) and Purity screens by prioritizing existing replicate data over default initialization, improving data accuracy and user experience. Implemented SMP breeding values integration into parent tree calculations by introducing SeedlotManagementBreedingValueDto, updating PtValsCalReqDto to accept SMP contributions, and enhancing ParentTreeService to incorporate SMP contributions. These changes strengthen data integrity, enable more precise selection decisions, and lay groundwork for future SMP-driven improvements. Overall, the month reduced risk of misrepresented results and enhanced the reliability of breeding value estimations, contributing to better business decisions and downstream outcomes.
