该品种是原吉林省四平市农业科学院培育的中早熟品种,生育期116d左右,植株较矮,抗倒伏。抗病,活秆成熟,果穗较长,喜肥水,增产潜力大,适宜在宾县、通河、鸡西、密山等地种植。但是该品种制种难度大,由于花期相遇不好,结实率低,制种产量最低时仅为750kg/hm~2左右。导致制种结实率低的主要原因是父本雄穗分枝少(约为3～5个)而短,花粉量少,花期短(为15d),因此导致产量低。为了解决该品种制种产量不稳定的问题,笔者采用父本一期播种三期花粉的方法,在2000年度和2001年度进行了制种稳产试验,连续2年制种产量稳定在2250kg/hm~2以上,高产户产量达到3300kg/hm~2。
This variety is the middle-early-maturing variety cultivated by former Academy of Agricultural Sciences in Siping City, Jilin Province. The growth period is about 116 days, and the plants are short and lodging resistant. Resistant to disease, living stalk maturity, ear longer, hi fertilizer, yield potential, suitable in Binxian, Tonghe, Jixi, Mishan and other places planted. However, it is very difficult to seed the seed, but it is only 750kg / hm ~ 2 when seed yield is the lowest due to the poor flowering and low seed setting rate. The main reason for low seed setting rate is that the male tassel branches have few branches (about 3 to 5) and short, less pollen and short flowering period (15d), thus resulting in low yield. In order to solve the problem of instability of seed yield of this variety, the author adopted the method of sowing the third pollen of the male parent in the first crop in 2000 and 2001, and the seed production was stable at 2250kg / hm ~ 2 or more, high yield reached 3300kg / hm ~ 2.
