Bean purifying and rejuvenating method
The degraded varieties of beans often exhibit delayed maturity, low yields, and poor quality. To restore their vigor and quality, a purification and rejuvenation method can be applied. This involves isolating the bean plants to prevent unwanted cross-pollination. Since self-pollination is the primary mode, the natural hybridization rate typically remains below 4%. However, factors such as variety characteristics, environmental conditions, or wind can increase this rate, sometimes exceeding 10%. Therefore, it's essential to maintain proper isolation distances: at least 80–100 meters for original seed production areas and more than 20 meters for general production areas.
To ensure purity, careful selection is necessary during the breeding process. Three key stages should focus on removing undesirable plants. First, during the early flowering stage, remove any diseased, weak, or deformed plants. Second, when the first batch of pods reaches harvest readiness, eliminate any off-type plants based on their visible traits. Third, before final harvesting, inspect mature pods and seeds to remove any remaining impurities that do not conform to the desired variety characteristics.
Selecting high-quality bean plants can be challenging, especially when choosing individual plants with strong pod development. One effective approach is to identify the best plants in the field and collect their seeds together after they reach the harvest stage. These seeds are then threshed and stored collectively to preserve the desired traits.
After sowing in the second year, field identification is crucial. If the plants meet the variety standards, they can be mixed and preserved as original seeds. Alternatively, select the most promising plants, harvest them individually, and plant them separately in the following season. If they continue to meet the variety requirements, they can be used for producing hybrid mixtures intended for original seed stock.
This process ensures that only the healthiest, most uniform, and true-to-type plants are retained, leading to improved yield, quality, and consistency in future generations of beans.
