Abstract
In order to get a better understanding of the general situation and grain quality traits of the rice varieties registered in Hunan Province,230 rice varieties in Hunan Province registered from 2022 to 2024 were taken as the research objects,and the indexes were comprehensively analyzed and evaluated by means of coefficients of variation and correlation.The results showed that the number of registered varieties developed by different types of breeding units was in the order of enterprises＞joint venture of scientific research institutes and enterprises＞scientific research institutes.The high-quality rate of rice was in the order of three-line hybrid rice＞conventional rice＞two-line hybrid rice,late-maturing late season rice＞medium-maturing late season rice＞late-maturing early season rice＞single season rice＞late-maturing medium season rice＞medium-maturing early season rice.The high-quality rate of the six grading indexes of high-quality rice was as follows:head rice rate＞gel consistency＞transparency＞amylose content＞alkali spreading value＞chalkiness degree,and the first-grade compliance rate was as follows:gel consistency＞amylose content＞head rice rate＞alkali spreading value＞transparency＞chalkiness degree,indicating that chalkiness degree and alkali spreading value were the key indexes affecting the entry of the registered varieties into high-quality rice,and chalkiness was the key factor restricting the entry of registered varieties into the first-grade high-quality rice.The correlation analysis of each grain quality index showed that the quality traits had different degrees of correlation.Among them,the sensory evaluation of rice cooking and eating was significantly positively correlated with head rice rate,length-width ratio and the alkali spreading value,and it was significantly negatively correlated with the chalky grain rate and chalkiness degree.关键词
