“汕优22”系四川省农科院作物所彭兴富副研究员以“珍汕97A”与自选新恢复系”CDR22”(2R50×明恢63多代选择)于1988年组配而成。一、“汕优22”的生产能力“汕优63”是继“汕优2号”统治全川杂交稻之后的又一主栽品种,“汕优22”与“汕优63”相比,其生产潜力如何呢? (一)控制性品比试验 1988年配合力鉴定试验。“汕优22”亩产428.6公斤,比对照增产13.8％。 1989年组合对比试验亩产611.4公斤,比对照增产4.2％。 1990年南方稻区“超高产水稻新品种(组合)栽培特性与技术对策协作组”在五省8个点的4次重复试验,“汕优22”平均亩产493.73公斤,比“汕优63”494.94公斤亩减0.21公斤,产量持平。其小四省5点增产:四川农科院广汉点和湖南农学院点增产2.9％和3.0％(亩增16.6公斤
“Shanyou 22” Department of Sichuan Academy of Agricultural Sciences Peng Xingfu associate researcher in the “Zhenshan 97A” and optional new restorer “CDR22” (2R50 × Ming Hui more than 63 generations to choose from) in 1988. One, “Shanyou 22” production capacity “Shanyou 63” is the second major variety “Shanyou 2” ruled the whole Sichuan hybrid rice, “Shanyou 22” compared with “Shanyou 63” Its production potential? (A) control sex ratio test 1988 appraisal of combining ability. “Shanyou 22” per mu 428.6 kg, 13.8% increase over the control. In 1989, the combined control trial output per unit area was 611.4 kg, 4.2% more than the control. In 1990, the cooperation group of cultivation characteristics and technical measures of new super-high-yielding rice varieties (combinations) in southern rice area was tested in 4 replicates at 8 points in 5 provinces. The average yield of “Shanyou 22” was 493.73 kg per mu, "494.94 kilograms mu minus 0.21 kilograms, the output is flat. Its small four provinces increased production 5:00: Sichuan Academy of Agricultural Sciences Guanghan point and Hunan Agricultural College point of increase of 2.9% and 3.0% (mu by 16.6 kg
