The selection of improved rice varieties is a key strategy for boosting rice yields. As such, it is crucial to ensure the proper selection and preservation of traditional late rice varieties. This process should not be overlooked or underestimated. So, how can farmers effectively carry out seed selection for late rice production? Based on my experience, there are four essential steps that should be followed:
First, pay close attention to the fields selected for seed production. Choose plots from fine conventional rice varieties that have been grown in the previous season. These fields should feature healthy plants, balanced growth, full grains, uniform maturity, and no signs of pests or diseases. The best time to evaluate these fields is during the yellow ripening stage of the rice.
Second, focus on removing impurities. Once the plots have been selected, thorough efforts must be made to eliminate any unwanted plant strains. This cleaning process needs to be done carefully and repeated multiple times to ensure all off-types are removed, maintaining the genetic purity of the seeds.
Third, ensure careful harvesting and drying. Only select specific plots for harvesting, and make sure that each plot is harvested and dried separately. Use clean tools and avoid mixing different varieties during the process. The drying area should also be kept clean and free from contamination by other rice types. This helps maintain the quality and purity of the seeds.
Fourth, pay attention to storage conditions. After harvesting, the seeds should be thoroughly dried under the sun to reduce moisture content to below 13%. Store them in sealed packages in a dry, well-ventilated warehouse. Apply disinfectants to prevent pests and rodents from damaging the seeds. Regular inspections during storage are essential to monitor for any signs of mold or deterioration. Proper storage ensures that the seeds remain viable and ready for planting when needed.
