摘要
恩施州是我国稻瘟病常发重发病区之一,水稻品种在该地区的农业生产上使用年限短,针对这一特点,实施品种试验和品种审定是良种更新换代的最有效途径.本研究拟对2012-2014年恩施州迟熟组水稻新品种试验中13个参试品种的产量、生育期、农艺性状、抗性、品质等主要指标进行系统鉴定和评价,评选出适宜该区域种植的优质多抗高产杂交水稻新品种,以期为恩施州水稻品种审定提供科学依据,对促进恩施州现代种业可持续发展具有重要意义.
Enshi Prefecture is one of the zones in which the rice blast occurs frequently and seriously in China,so the time of rice varieties used on agricultural production is very short in the Enshi mountainous areas. Based on this characteristic,carrying out new rice varieties test and cultivar registration is the most effective way to solve the above-mentioned problem. In this study the new rice regional trial and produc?tive test of late-maturing group in Enshi were implemented from 2012 to 2014,in order to appraise and e?valuate systematicly the main indexes of 13 testing rice varieties,such as yield,growth period,agronomic traits,resistance,quality,etc.Through selecting high-quality, multi-resistance and high-yield hybrid rice varieties which are suitable to be cultivated in this area.These research results will provide a scientific ba?sis for Hubei Provincial Variety Examination and Approval Committee to register new good rice cultivars, and be much helpful to improve the regional sustainable development of modern seed industry.
