Abstract
A systematic comparative analysis was conducted on the rice planting situation,advancements in independent variety breeding,and changes in market share in Xing'an League,from 2001 to 2023.The results indicated that during the period from 2022 to 2023,the rice planting area in Xing'an League remained stable at approximately 62,000 hectares,which was 2.37 times the average cultivation area over the 15-year period from 2001 to 2015.Simultaneously,the total rice output also exhibited a significant and corresponding increase.In terms of yield per unit area,it demonstrated a long-term and steady upward trend from 2001 to 2023.Particularly since 2016,the yield per unit area has reached 2.01 times that of 2001,fully highlighting the remarkable achievements in cultivation techniques and variety improvement.In the area of independent variety breeding,Xing'an League has also achieved remarkable accomplishments.Among the rice varieties approved by the autonomous region,the number of independently bred varieties increased from 0 in 2001 to 11 in 2023,with their proportion rising from 0%to 47.54%.This change not only enriched the diversity of rice varieties in Xing'an League but also provided a strong impetus for the sustainable development of the rice industry.Influenced positively by the increase in the number and quality of Xing'an independently bred varieties,the market share of Xing'an League's independently bred rice varieties has also experienced significant growth,rising from 23.30%in 2017 to 61.00%in 2023.This marks a leapfrog development in Xing'an League's high-quality rice industry,successfully transitioning from a situation of'weak seeds,strong rice,weak grain products'to one of'strong seeds,strong rice,strong grain products'.Looking ahead,to further consolidate and expand these development achievements,it is recommended to strengthen the construction of variety breeding clusters.By optimizing resource allocation and enhancing scientific research and innovation capabilities,the virtuous cycle mechanism of"strong seeds,strong rice,strong grain products"can be further reinforced.Meanwhile,the government should increase policy support for Xing'an League's leading high-quality rice industry,providing comprehensive guarantees in terms of funding,technology,and markets to help Xing'an League's high-quality rice industry reach a higher level of development.关键词
