湖南杂交水稻研究中心,经多年转育已培育出香稻不育系,与5个非香稻恢复系配组,1986年秋在广西南宁小面试种,F_1表现很有苗头。这五个组合,在南宁8月6日播种,8月20日移栽,9月27~30日始穗,11月2~5日成熟。全生育期86~89天,属倒种春种植的早稻组合。株高85~89厘米,穗长19.2~20.8厘米,穗粒数118.7~152.7粒,结实率79.9~89.9%,千粒重
Hunan hybrid rice research center, after years of transplanting have developed male sterile lines, and 5 non-fragrant rice restorer line group, the autumn of 1986, Nanning, Guangxi small surface test species, F_1 performance is very signs. The five combinations are sown on August 6 in Nanning, transplanted on August 20, spikelets started on September 27-30, and matured on November 2-5. The whole growth period of 86 to 89 days, is an early spring rice planting hybrid rice combination. Plant height 85 ~ 89 cm, spike length 19.2 ~ 20.8 cm, grain number 118.7 ~ 152.7, seed setting rate 79.9 ~ 89.9%, 1000-grain weight
