一、WF_9×C_103 WF_9×C_103是芳草湖总埸试验站一九七二年用自交系WF_9作母本、C_103作父本配制成功的。 WF_9×C_103株高2.2—2.7米,叶片较短,斜上举,节间较长,通风透光较好,适于密植(3400株/亩),分蘖少(约20％),穗位90厘米左右,穗长23—25厘米,穗粒行14—20行,子粒黄色,马齿型,穗轴紫色,单穗子粒重210—297克,百粒重35—37克,子粒出产率82.3—83.4％。WF_9×C_103的子粒品质比双交156好,其成熟期此双交156早7天左右。
First, WF_9 × C_103 WF_9 × C_103 Fangcao Lake total station test station in 1972 with inbred WF_9 as the mother, C_103 as the father of the preparation of the formula. The plant height of WF_9 × C_103 is 2.2-2.7 m, the leaves are short, the ramps are upwards, the internodes are longer, the ventilation and light are better, which is suitable for close planting (3400 plants / mu) Cm, spike length 23-25 cm, spikelets line 14-20 lines, yellow, dentate, cob purple, single grain weight 210-297 grams, 35-37 grams of grain weight, grain yield 82.3 -83.4%. The grain quality of WF_9 × C_103 was better than that of double crosses 156, and the maturity of this double crosses 156 was about 7 days earlier.
