以Ｗ６１５４Ｓ为母本，Ｃｐ—ＳＬＯ１７为父本于１９８８年杂交配组，在后代中经定向选择，于１９９１年育成Ｗ９１６０７Ｓ，１９９４年通过湖北省科委的技术鉴定。Ｗ９１６０７Ｓ在武汉自然条件下７月２５日至９月１０日抽穗为稳定不育期，花粉和小穗自交不育度均在９９．５％以上。１０００株以上群体遗传性稳定，花粉不育度９９．９９％，小穗自交不育度９９．８８％。在育性对温度的敏感期进行日平均温度２４℃、光照１４ｈ处理，花粉平均不育度９７．８％，小穗自交平均不育度９９．１％，在武汉自然条件下，９月１３日以后抽穗为可育期，但可育度较低，花粉和自交可育度２％～６％。在海南陵水３月初抽穗，自然结实率２８％～６６％。在武汉播始历期１０３ｄ（３月２５日播）～８２ｄ（６月２０日播），主茎叶片数１６．２～１４．０片，属长江流域的中籼型品种。株高９４ｃｍ左右，穗长２６．５ｃｍ左右，每穗总粒数１４０～１５０粒。开花顺畅，花时集中，柱头外露率３０．２２％～４８．６２％。配合力较强。
Using W6154S as the female parent and Cp-SLO17 as the male parent, the hybrids were crossed in 1988 and selected by the offspring. In 1991, it was bred as W91607S, and passed the technical appraisal of Hubei Science and Technology Committee in 1994. W91607S in Wuhan from July 25 to September 10 in the natural conditions of heading for the period of sterile, pollen and spikelet self-fertility are more than 99.5%. More than 1000 strains of hereditary stability, pollen sterility 99.99%, spikelet self-fertility 99.88%. During the sensitive period of fertility to temperature, the average daily temperature of 24 ℃, light 14h treatment, average pollen sterility 97.8%, spikelet self-fertility average fertility 99.1%, in Wuhan natural conditions, September After 13 days, the heading date was fertile, but the fertility was low, pollen and selfed fertility was 2% -6%. In early March, Hainan Lingshui heading, the natural seed set rate of 28% to 66%. In Wuhan, the dates of 103d (sowing on March 25th) ~ 82d (sowing on June 20) are 16.2 ~ 14.0 pieces of main stem leaves, belonging to the medium indica varieties in the Yangtze River valley. Plant height about 94cm, spike length 26.5cm or so, the total number of grains per spike 140 to 150. Flowering smooth, spend time concentrated, stigma exposed rate of 30.22% ~ 48.62%. Strong combination.
