花单1号是利用玉米花培纯系与常规自交系组配选育而成的一个单交种。1986—1987年参加广西玉米区试,名列第一。1988—1989年是广西玉米区试对照种,并被推荐参加西南7省(区)玉米区试。与此同时,在广西各地进行生产力鉴定和试种示范。试种结果表明,花单1号均比当地推广的杂交种增产。1992年,自治区农业厅把花单1号列为广西“八五”期间主要推广的杂交玉米良种之一。到目前为止,花单1号已在广西各地累计推广面积约7万亩。
Hua Dan No. 1 is the use of popcorn purebred lines and conventional inbred lines with a single cross breeding. From 1986 to 1987, she took part in Guangxi corn area trial, ranking first. 1988-1989 was a pilot crop of Guangxi maize area trial and was recommended to participate in the corn area trial of 7 provinces (autonomous regions) in southwest China. In the meantime, demonstration and trial production of productivity has been carried out throughout Guangxi. The results of trial planting showed that flower number 1 increased yield compared with the hybrids promoted locally. In 1992, the Department of Agriculture of Xinjiang Uygur Autonomous Region named Huadan No.1 as one of the main varieties of hybrid maize to be popularized in Guangxi during the “Eighth Five-Year Plan” period. So far, Hua Dan No.1 has accumulated a total area of about 70,000 mu across Guangxi.
