Xinhai No. 41 (the original code 06-146) is Xinjiang Tahe seed industry R & D center using high resistance to Fusarium wilt resistant source material as female parent, and has strong boll, quality of lines as male parent and disease resistance, early maturity, high yield cotton new lines. May 2012 approved by the the Xinjiang Uygur Autonomous Region crop variety Approval Committee named.
First, the characteristics of the characteristics
The varieties of the growing period of about 142 days type, tube type, more compact, height of 120 cm, stem thick, corolla yellow; zero branches. Cotyledon kidney type, light leaf color, leaf split 5 pieces, a deep, leaf size, leaf color dark green leaves, less hair. In the bell type, there was a clear oil gland point on the bell surface, the bell mouth was pointed, and the bell room was more than 3. Single boll weight 3.44 G. The smooth and concentrated, good picking flowers, color white floc. The strong adaptability, not premature aging, resistance to leaf disease, high resistance to Fusarium wilt, Verticillium wilt resistance. On the early flowering boll, boll, boll opening, Chang Yi picking flowers, good harvest.
Two, production performance
2009-2010 two years average test results: per mu of seed cotton and lint, pre frost lint yield respectively kg 330.59, 112.46 kg, 106.31 kg, respectively for control 108.14%, 111.57%, 111.26%. Flower before frost was 94.72%, boll weight 3.44 grams, lint percentage 33.23%. 2010 autonomous region in southern Xinjiang long staple cotton production test, with per mu of seed cotton and lint, pre frost lint yield respectively kg 355.31 and 114.42 kg, kg 109.94, respectively for control of 99.17%, 102.18%, 101.85. General Oda lint yield over 140kg/ mu, high yield and lint yield of about 160kg/ mu tian.
Three, fiber quality:
In 2009 and 2010 two regional trials and 2011 production test of fiber quality average: 3.666 mm on average half the length, fracture than strength 45.65 cattle / tex, micronaire value 3.96 and elongation at break of 5.36%, neat index 88.75%.
The disease resistance was identified by the autonomous region: the disease index was 0.69, and the disease resistance was high. Verticillium wilt disease index 43.84, resistant to Verticillium wilt.
Four, cultivation techniques:
1 sowing date and sowing density: in mid April, 13000 - 15000 plastic mulching cultivation, seedling plants / mu.
2. The fertilization and irrigation: base fertilizer oil check 80 - 100kg/mu, urea 20kg/mu, three material phosphorus 15kg/mu, under furrow irrigation and fertilization twice, first head of urea 8kg/mu, diammonium 7kg/mu, second second water before urea 10kg/mu. Irrigation 4 times, 8 months late without water, fertilizer, drought and prevent late. Under the condition of drip irrigation, dripping about 10 times, each content in the 20-30 square, topdressing available special fertilizer for drip irrigation, or urea, amount of potassium dihydrogen phosphate, fertilizer with with water application, drip application 6 times, respectively in the early late October, 7 June and mid July and late July, early August, mid August.
3: according to the cotton growth, light adjustment, height control in 110-120cm.
