棉花新品系“4947”于1978年采用复式杂交{[(5006×1080)(3762×木槿)]F_1×豫79}F_1,经两次南繁加代,于1982年育成。该品系遗传基础较丰富,总体性状表现良好。现将几年来的试验观察和各地示范鉴定结果简报如下。 农艺性状:该品系子指较大(10克以上),出苗好,易全苗。顶端生长势较强,植株较高,中等肥力的棉田,一般在120厘米左右,株呈塔型。果枝上举,与主茎所成的夹角小,约为60度,故高而不大,松而不散。主根发达,主茎细硬,高而不倒。叶片中等大,叶量适中,色深绿,叶光滑,肉质厚,缺刻深且突起,后期较耐低温和较抗叶跳
The new line “4947” of cotton used double crosses {[(5006 × 1080) (3762 × hibiscus)] F_1 × Henan 79} F_1 in 1978, The genetic basis of the line is rich, the overall traits performed well. Now several years of experimental observation and demonstration results around the briefing is as follows. Agronomic traits: The pedigree refers to the larger (10 grams or more), emerge, easy whole seedlings. Strong growth potential at the top, higher plant, medium-fertile cotton fields, generally about 120 cm, strains were tower. Fruit branches on the move, and the angle formed by the main stem is small, about 60 degrees, it is high rather than loose, loose and scattered. The main root developed, the main stem fine, high and not down. Moderate leaf mass, dark green color, smooth leaves, thick flesh, lack of deep and protruding, the latter more resistant to low temperature and more anti-leaflet jump
