Boll 8 grams of cotton
The average single boll weight of this variety is 8 grams, and the maximum single boll weight is 9.2 grams. Clothing percentage 41.5%, sub-refers to 11.1 grams.
Second, good seedling emergence of this variety with 40000g / mu seed, strong germination potential, good seedling emergence and strong seedling.
The growth period of the variety is about 128 days, the leaves are of medium size, and the ventilation and light transmittance are good. The plant height is 105 cm, the cotton plant is clean, and the ability of fruit branch extension is strong. Cotton bolls are evenly distributed in the lower, middle, upper, inner and outer parts of the plant, and the boll weight is the same.
Fourth, the variety has good resistance to cotton bollworm, strong resistance to Fusarium wilt and Verticillium wilt, drought tolerance, alkali tolerance and no premature senescence.
Fifth, the variety has high yield, sparsely planted large trees, and has great potential to increase yield per plant. It is suitable for non-pruning cultivation in high fertilizer land (1500 plants per mu), and can also be planted in middle and lower soil fertility (2000,2500 plants per mu). The yield of seed cotton per mu is up to 602.9 kg in plot experiment.

Lu 05h9 pioneered Cotton Marker breeding in China
Recently, a new safflower marked insect-resistant hybrid cotton variety Lu 05H9 selected by the Cotton Center of Shandong Academy of Agricultural Sciences has been examined and approved by the National crop Variety approval Committee. The safflower mark is like putting an anti-counterfeiting label on the transgenic insect-resistant hybrid cotton. This variety has created a precedent of cotton safflower trait marker breeding in China, and it is also the first case in the world. According to researcher Wang Liuming of variety breeding, Lu 05H9 safflower marked insect-resistant cotton transferred the HB safflower character of wild Bick cotton to cultivation through distant hybridization for 12 years.
