Synergistic optimization of crops by combining early maturation with other agronomic traits

Many newly created early maturing varieties exhibit poor stress resistance and low yield, whereas stress-resistant varieties are typically late maturing. For this reason, the polymerization of early maturity and other desired agronomic qualities requires overcoming the negative connection between early maturity, multi-resistance, and yield, which presents a formidable challenge in current breeding techniques. We review the most salient constraints of early maturity breeding in current crop planting practices and the molecular mechanisms of different maturation timeframes in diverse crops from their origin center to production areas. We explore current breeding tactics and the future direction of crop breeding and the issues that must be resolved to accomplish the polymerization of desirable traits in light of the current obstacles and limitations.

Automated summary

The breeding of early maturing varieties faces constraints due to negative correlations between stress resistance, yield, and early maturity. Overcoming these constraints and achieving the combination of early maturity with other desirable agronomic traits poses a challenge in current breeding techniques. This review explores the limitations and obstacles in early maturity breeding and discusses the molecular mechanisms of maturation timeframes in different crops, as well as current breeding strategies and future directions to achieve the polymerization of desired traits.
