77-130系1974年用74-浙原1758(早熟3号~(60)CO辐射矮干突变体)为母本,南74-17(天然杂种高杆早熟二棱元麦)为父本杂交而成。当年夏季异地繁殖F_1,1975年从F_2中选择39株夏繁,1977年进入病因鉴定,表现较抗黄花叶病,种植面积迅速扩大。1980年,郊区秋播约3万亩,其中南汇县1万2千余亩。1979年,浙江省引入病区种植,反映也较好。 (一)特征特性:77-130属春性二棱大麦。幼苗半散伙,叶片比早熟3号略大,而色较深,剑叶叶耳紫色,腊熟期芒尖淡紫色,穗子上下稍窄,中部稍宽。无病区株高100厘米左右,比早熟3号矮8厘米。有效穗数
77-130 was the female parent of 74-Zheyuan 1758 (early maturing 3 ~ (60) CO radiation dwarf mutant) in 1974, and the South 74-17 And into. In the same year, F_1 was propagated off-site in summer of that year, and 39 strains of summer fox were selected from F_2 in 1975. In 1977, the disease was identified as etiological factor, showing more resistance to yellow mosaic disease and the area under cultivation expanded rapidly. In 1980, suburban autumn about 30,000 acres, of which more than 12,000 acres of Nanhui County. In 1979, Zhejiang Province introduced ward planting, reflecting better. (A) Features: 77-130 is a spring two-row barley. Seedlings half scattered partner, leaves slightly older than No. 3 slightly larger, darker color, purple leaves sword ears, waxing lavender lavender, spike a little narrow, slightly wider in the middle. Disease-free plant height of about 100 cm, shorter than the early No. 3 8 cm. Effective spike number
