Investigation and analysis of planting varieties and qualities of high quality paddy in Guangxi

Abstract

The planting varieties and qualities of 154 new high-quality paddy samples harvested in Guangxi in 2018 were investigated and analyzed in this paper. The results showed that abundant resources of high quality paddy varieties were planted in Guangxi, such as bai-xiang, silk fragrance, wild fragrance, oil percentage and silk seedlings. The food quality scores of the collected paddy samples all meet the requirement of grade III standard (≥70 points) specified in GB/T 17891—2017, 92.2% of the paddy samples could meet the requirement of grade II standard (≥80 points), and 9.7% of the paddy samples could meet the requirement of grade I standard (≥90 points). According to the requirements of high quality paddy amylose content (dry basis) range (14.0%~24.0%), 70.8% of the paddy samples could meet the requirements, and 29.2% of the total number of samples (45 paddy samples) was less than 14.0%, which did not meet the requirements of the standard, but 38 paddy samples of them could meet the requirement of grade II standard (≥80 points) specified in GB/T 17891—2017. The survey results showed that the whole quality of the newly harvested high quality paddy in Guangxi was excellent.
