摘要
为进一步了解彩色稻种质资源,筛选出适合珠三角地区观光农业发展需要的彩色稻品种,收集引进了 24 个不同彩色水稻品种(系),分早晚两造与本地主栽品种美香占 2 号(对照)进行农艺性状比较试验,对生育期、生长动态、株高、产量、抗性等进行综合分析.结果表明,11 个紫色品种的生育期、株高、分蘖率与对照相对接近,产量除紫色稻晚造增产外,其余均比对照低;5 个白色品种生育期比对照长、分蘖率高、株高偏矮、产量均比对照低;8 个黄色品种生育期,除江黄、云黄生育期比对照长外,其余生育期比对照短,株高偏矮,产量除坚黄 2 号早造增产外,其余均比对照低.综合考察24 个不同彩色稻品种,较适合广东珠三角地区用于观光农业"稻田画"等创作应用的紫色品种有紫红 1 号、花紫、优紫,黄色品种有坚黄 2 号、黄叶稻、江黄,白色品种有海白、江白.
Abstract
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.
