(一)选育经过:1973年夏凡,从“阿夫”选出变异单株,74年在穗行圃中表现抗逆性强,丰产性好,75年升入穗系侧产圃,亩产324.5斤,比对照“阿波”增产81.9％,在62份材料中居首位,77及78两年参加省区域试验,77年在11个试点中,平均亩产392.5斤,比对照增产7.65％,居首位,其中8个试点较“阿波”增产,增产率0.69～39.27％,增产不足10％的2个点,10％以上的3个点,20％以上的3个点,78年14个试点平均亩产413.3斤,比“阿波”减产3.56％。其中5个试点较“阿波”增产,增产率10.8～25.6％。
(A) after breeding: 1973, where the spring, from the “Avr” selected mutants, 74 years in the spike nursery performance of the strong resistance, high yield, 75 years into the panicle side nursery, A yield of 324.5 kg, an increase of 81.9% over the control “A-wave”, ranking the first among 62 materials and 77 and 78 years in the provincial regional experiment. In 11 of 77 pilot years, the average output per mu was 392.5 kg, 7.65% , Of which 8 were more successful than the “A-wave”, with an increase rate of 0.69-39.27%, an increase of less than 10%, 3 more than 10%, 3 more than 20% and 78 14 A pilot average yield of 413.3 kg, compared with “Aba” cut 3.56%. Five of the pilot projects increased production compared to “Abo”, with a yield increase of 10.8% to 25.6%.
