The current pace of yield increase for major crops is not fast enough to meet future demand. Crop breeding programmes are under increasing pressure improve existing further. Quantifying the contribution these observed increases important evaluating their success and identifying if crop improvement goals likely be met. In this paper we explore methods study genetic gain two cereal species, wheat (Triticum aestivum L.) barley (Hordeum vulgare L.). Specifically, objective research was identify sources bias in estimates UK variety trials data. Genetic estimated fungicide-treated untreated winter wheat, spring 1982–2018 using National List Recommended Subsets dataset were used replicate shorter cycles quantify impact number choice long-term check varieties on estimating gain. While non-genetic contributions changes performance line with previous estimates, able previously undetected biases performance. an difference between fungicide treated as age, driven by both a breakdown disease resistance unobserved age trials. This shows that yields cannot assumed stable over time. We found highly sensitive chosen, whilst inclusion multiple checks decreased standard error estimate. estimation susceptible bias. provide recommendations how reduce risk Accounting calculations any programme selection prevent inaccurate quantification progress.

Current research topic delves into subjects ranging from fundamental mechanisms of reproductive biology to practical strategies for enhancing crop resilience under environmental stresses. Since seed-based traits are pivotal in maintaining and conferring biodiversity, insights their development adaptation critical cope with issues like climate change, food scarcity, e;ective management underutilized marginal lands.This focused issue presents four unique contributions, each o;ering di;erent aspects plant reproduction seed-related traits. While some these studies align directly ovule seed development, others provide complementary perspectives, broadening the narrative topic.Seed via sexual essentially relies on successful delivery male gametes fuse egg cell residing embryo sac female gametophyte. Hence, coordinated precise is essential process. Here, Cui et al. discuss molecular behind microsporogenesis micro-gametogenesis references recent relevant studies.
