专用型两系杂交早稻组合株两优06的选育与应用

Breeding and Application of Two-line Early Hybrid Rice Combination Zhuliangyou 06 with a Special Use for Processing

株两优06是采用温敏不育系株1S与早籼恢复系06EZ11配组育成的两系杂交早稻组合,具有熟期适宜、丰产性和稳产性好、分蘖力较强、植株较矮、抗倒力强、千粒重大和适应性广等特点,其稻米的直链淀粉含量高达26.8%,是米粉等食品加工专用的最佳原料。2010年通过湖南省农作物品种审定委员会审定,2018年通过江西省引种备案。文章介绍了该组合的选育过程、特征特性、高产栽培和制种技术及推广应用。

Zhuliangyou 06,derived from Zhu 1 S(TGMS line)/06 EZ11(early indica restorer line),is a two-line early hybrid rice combination.It is characteristic of suitable maturity,stable and high grain yield,strong tillering ability,relatively short plant height with strong lodging resistance,heavy 1 000-grain weight and wide adaptability.Its amylose content in rice grain is as high as 26.8%,so it is the best raw materials for a special food processing such as rice noodles.It was registered and released to commercial production by Hunan Provincial Crop Variety Appraisal Committee in 2010,and approved to be introduced into Jiangxi Province in 2018.The breeding procedure,characteristics,popularization and major applied techniques in high-yielding cultivation and hybrid seed production of Zhuliangyou 06 were introduced in this paper.
