【摘要】 利用光温敏核不育系2136S与恢复系M86配组。育成了优质高产两系杂交稻新组合黔两代58。经两年贵州省早熟组杂交稻区试鉴定,平均单产8.51t/hm~2,比对照平均增产5.66%;一年生产试验鉴定,平均单产8.28t/hm~2,比对照平均增产10.11%;在贵阳进行两年高产栽培试验,平均单产达10.99t/hm~2。黔两优58对稻瘟病的抗性优于对照,耐寒性强。稻米理化指标则试和食味鉴评结果表明品质较优,是适合中高海拔地区种植的优质高产杂交稻理想组合。黔两优58于2004年4月通过贵州省农作物品种审定委员会审定。
【Abstract】 Qian Liangyou 58, a new two-line hybrid rice combination with high-yielding and good quality was devel-oped from the cross between an indica dual-purpose genic male sterile line 2136S and a male parent M86. The average yieldof Qian Lianyou 58 was 8. 51t/hm~2, 5.55% higher than that of CK combination in multiple-location regional experimenttests for two years, 8.28t/hm~2, 10.11% higher than that of CK combination for one-year productive experiment in five lo-cation tests in Guizhou Province, and 10. 99t/hm~2 in two-year high-yielding cultural experiment at Guiyang. Qian Liangyou 58 is of characteristics with high and stable yield, good grain quality, wide adaptability, better resistance to blast andstrong tolerance to low temperature. The new combination is suitable for middle-high elevation regions and has good pros-pect of utilization. It was registered as commercial variety in 2004 in Guizhou Province.
