抗虫棉品种赣杂棉0906的特性及其栽培技术

Characteristics of the Insect-resistant Cotton Variety Ganzamian 0906 and its Cultivation Techniques

赣杂棉0906是利用抗虫棉品系HK003和优质棉品系赣棉47系选配而成的杂交组合,具有品质优、产量高、抗虫性好、抗枯萎病等优良性状,经江西省棉花品种区域试验表明,2010年和2011年两年平均皮棉产量1633.5kg/hm^2,比对照赣棉杂1号增产2.20%;蕾期和结铃期枯萎病相对抗指分别10.9、19.7,耐枯萎病;纤维上半部平均长度30.1mm,长度整齐度指数84.8%,断裂比强度30.05cN/tex,断裂伸长率4.7%,马克隆值4.5,反射率78.2%,黄度7.5,纺纱均匀性指数146.2。经农业部科技发展中心检验,赣杂棉0906对二代、三代、四代棉铃虫幼虫的校正死亡率分别为73.6%、49.2%和62.2%;比阳性对照品种(GK19)分别增加10.8%、1.7%和降低4.9%,为"抗"棉铃虫品种。2015年通过江西省农作物品种审定委员会审定。

Ganzamian 0906 is a good hybrid combination with good fiber quality, high yield, good insect resistance, re- sistance to fusarium wilt, and it was bred through the hybridization between insect - resistant cotton line HK003 and high qual-ity cotton line Ganmian 47. The results in the new cotton varieties regional test in Jiangxi province showed that： the average lint yield in 2010 and 2011 was 1633.5 kg/hm^2 increasing 2.20% compared with the control varitey Ganmianza No. 1 ; the rel- ative resistance to Fusarium Wilt in bud stage and boll stage respectively were 10.9 and 19.7, tolerance to Fusarium Wilt ; the upper half mean length was 30.1 nun, uniformity index was 84.8%, breaking tenacity was 30.05 cN/tex, breaking elongation was 4.7%, mieronaire was 4.5, reflectance degree was 78.2%, yellowness was 7.5, spinning consistency index was 146.2. With the inspection by Science and Technology Development Center of the Ministry of Agriculture, the adjust mortality ratio of the Ganzamian 0906 to the cotton bollworm＇ s second generation, three generation and four generation respectively were 73.6%, 49.2% and 62.2%, respectively increasing 10.8%, 1.7% and decreasing 4.9% compared with the positive con- trol variety （Gkl9）, it was a cotton bollworm resistant variety. This variety was approved by Jiangxi Provincial Crop Variety Certification Committee in 2015.
