The inability to save hybrid seeds is not a conspiracy by seed companies but rather a consequence of scientific principles. This article thoroughly examines the characteristics of hybrid seeds compared to traditional saved seeds, explaining why second-generation planting of hybrid seeds yields poor results.
In recent years, with the advancement of agricultural technology, hybrid seeds have gradually become the primary choice for farmers. However, many farmers have noticed that hybrid seeds cannot be reused in the second year after planting, leading to significant declines in yield and quality. Some have questioned whether this is a conspiracy by seed companies, but experts point out that it's actually due to inherent characteristics of hybrid seeds, demonstrating the companies' responsibility towards farmers.
Why can't hybrid seeds be saved for planting?
Hybrid seeds are obtained by crossing pure parental lines with different genetic traits. They exhibit clear advantages: tall plants, well-developed roots, fast growth, drought and flood resistance, strong disease resistance, and high yields. However, these desirable traits cannot be stably inherited in the second generation of planting, often resulting in trait segregation. Second-generation hybrid plants vary in height, exhibit large differences in ear size, inconsistent maturity times, and significantly reduced yields.
The past and present of traditional saved seeds
In the past, farmers commonly propagated crops through saved seeds, selecting and retaining superior plants to save on seed costs and preserve the characteristics of excellent varieties. However, with the advent of hybrid seeds, saved seeds have gradually been replaced. The superiority of hybrid seeds has made them the preferred choice among farmers, but it has also led to the disappearance of many traditional varieties.
The rise of hybrid seeds and its impact
While the dominant rise of hybrid seeds has increased crop yields and quality, it has also reduced the market share of traditional seeds. Many traditional seeds are gradually disappearing due to reduced market demand and even face the risk of extinction. Despite the clear advantages of hybrid seeds in yield and disease resistance, traditional seeds still hold unique value in terms of quality and taste.
In conclusion, the inability to save hybrid seeds results from their genetic characteristics, not from intentional actions by seed companies. Scientifically planting hybrid seeds can help farmers increase production and income, but equal attention should be paid to protecting and preserving traditional varieties to maintain agricultural diversity and sustainable development.
