摘要
焦杂粳1号是焦作市农林科学研究院于2005年以不育系焦31A与焦恢2号配组育成的杂交粳稻新组合。2008和2009年参加河南省水稻中晚粳区域试验,产量分别为9.296和9.458 t/hm2,分别比对照增产17.2%和17.3%,2 a均居参试组第1位。该组合还具有米质较优、抗病性较强、适应性广等特点,适合河南省北中部粳稻区和南部籼改粳稻区栽培,2011年5月通过河南省农作物品种审定委员会审定。
Jiaozajing 1, derived from 3iao 31 A and Jiaohui 2 developed by Jiaozuo Academy of Agricultural and Forestry Sciences in 2005, is a new japonica hybrid rice combination. In 2008 and 2009, it was tested in the re- gional trials for medium and late japonica rice of Henan Province. Ranking first among all tested varieties in these two years, it yielded 9. 296 and 9.458 t/hm2, 17.2% and 17.3% higher than those of the control varieties, re- spectively. Besides, Jiaozajing 1 also shows acceptable grain quality, multiple disease resistance and wide adapta- bility. Certified by Henan Provincial Crop Variety Appraisal Committee in May, 2011, it was released to commer- cial production for the northern and central Henan japonica rice growing areas and the southern Henan areas with a tendency of altering indica to japonica rice.
