Transgenic Cotton Cotton 8

Yinmian 8 is a high-yield, multi-resistance transgenic insect-resistant cotton variety jointly selected by Beijing Yinland Biotechnology Co., Ltd. and the Institute of Biotechnology, Chinese Academy of Agricultural Sciences. Auditing No.: National Auditing Cotton 2008008.

Characteristics: Yinmian 8 is a three-line hybrid cotton with transgenic insect resistance. The spring sowing period of the cotton in the Yellow River Basin is about 122 days. Plants tall, loose plant type, less crazy branches, management labor. Stem thick, less hair. Good emergence, strong growth, good uniformity. The fruit branch averages 6.5 knots, the highest number of bolls per plant is 110, the bell is oval, the bell tip is obvious, and the concentration of flower bells is concentrated. The boll weight is 6.2 g, the lint percentage is 42%, the son finger is 10.3 g, and the frost flower is The rate is 92.4%. The shell is thin, it is easy to pick, and it is easy to pick. Strong pest resistance, no premature senescence, high yield, and good fiber quality.

Production performance From 2005 to 2006, we participated in the spring cotton group regional trials in the national cotton region of the Yellow River Basin. The yields of cotton, lint, and pre-frost lint were 233.1 kg, 93.9 kg, and 86.9 kg respectively, which was 5.6% higher than the control Lumianyan 15 respectively. 6.3% and 4.3%; In 2007, they took part in the production test of the middle-maturing hybrid group in the national cotton area of ​​the Yellow River Basin. The yields of cotton, lint, and pre-frost lint were 224.4 kg, 94.2 kg, and 88.2 kg respectively, which were higher than the control Lumianyan 15 respectively. 7.3%, 7.8% and 6.9%.

Cultivation points This variety is suitable for spring sowing in the cotton region of the Yellow River Basin. The transplanting of the seedlings for the nutrition seedlings is planted at the beginning of April, and the mulching cultivation is planted in the middle and early April. The open field is sown in the middle and late April. Planting 1800 to 2200 plants per acre in high-fertilizer plants, 2,500 plants per acre in medium-fertilizer plants, and more than 3,000 plants per acre in dry land. Apply enough base fertilizer, organic fertilizer applied per acre 2000 ~ 2500 kg, 20 kg of diammonium phosphate, potash 15 kg, early application of flower bell fertilizer, make-up cover roof fertilizer, extend the effective ringing period. Growth regulators are applied as appropriate, depending on the growth of the cotton and weather conditions. Topping up at the right time, doing a good job of whole-grassing. In case of drought, timely irrigation should be done to increase the boll weight.
