Agronomic Characters Comprehensive Analysis of 24 Different Germplasm Resources of Color Rice
To further understand the germplasm resources of color rice and screen out color rice varie-ties that are suitable for the development of tourism agriculture in the Pearl River Delta region,24 color rice varieties(lines)were introduced and conducted early and late planting experiments.Some agronomic traits such as growth period,growth dynamics,plant height,tillering rate,and resistance were compared with contrast Meixiangzhan No.2.The results showed that the growth period,plant height,tillering rate of 11 purple varieties were close to Meixiangzhan No.2,and yield were lower than Meixiangzhan No.2 except late cultivation Zise.Compared to Meixiangzhan No.2,the growth period of 5 white varieties were longer,the tillering rate were higher,the plant height were shorter,and the yield were lower.Meanwhile,the growth period of 8 yellow varieties were shorter,except Jianhuang and Yunhuang,and all plant height were shorter,the yield were lower,except early culti-vation Jianhuang No.2.After comprehensive analysis of 24 different color ricevarieties,the purple varieties Zihong No.1,Huazi,Youzi,yellow varieties Jianhuang No.2,Huangyedao,Jianhuang and the white varieties Haibai,Jiangbai were suitable for the creation and application of sightseeing agri-cultural rice field painting in the Pearl River Delta region of Guangdong Province.
