性频率98.4%~100%，其中对中B群96.9%~100%、中C群100%，两年区试比对照平均增产6.95%，生产上每667m2最高产量达到727.5kg，2011-2012年列为广东省农业主导品种。 |
| 英文摘要: |
| The combination of space mutagenesis and quality-resistance screening provides an efficient way for novel rice germplasm creation and new variety breeding. Huahang No. 31 was developed through cross breeding of new germplasm created by space mutation.This variety shows the characteristics of high-quality, high-yielding, disease-resistant. The rice quality reached the national standard of quality 2; the total resistance frequency ranged from 98.4% to 100%, of which the group B is 96.9% to 100% and group C is 100%. The average yield of the two-year regional test increased 6.95% than CK. The highest yield was 10.91 t/hm2 and was listed as one of the leading agricultural varieties in Guangdong Province in 2011 and 2012. |
