Introduction to the Characteristics of the Late Japonica Rice Variety Zhejing 30
I. Variety Introduction "Zhejing 30" was developed by the Institute of Crops and Nuclear Technology Utilization, Zhejiang Academy of Agricultural Sciences, in the spring of 1995 by crossing Xiushui 63 as the female parent with R9475. Through years of south propagation and north breeding, it was developed using a breeding method that combines low-generation selection for appearance quality (grain shape, transparency, chalkiness degree, chalkiness rate) and resistance identification in disease nurseries, with high-generation determination of physicochemical quality such as amylose content, taste testing, and resistance identification. It has been entered in trials at various levels since 1999, and passed the approval of the Zhejiang Provincial Variety Approval Committee in March 2003.
