Detailed Introduction to the Sesame Variety Ganzhu No. 3

The new sesame variety "Ganzhu No. 3", originally named B232, was developed by the Jiangxi Provincial Institute of Bast Fiber Crops through 12 years of breeding.

Characteristics: deep-rooted clump type, whole growth period 190d, of which the first crop 81d, the second crop 45d, and the third crop 64d. Plant height 172-198cm, stem diameter 1.0-1.2cm, fresh bark thickness 0.85mm, fiber extraction rate 12.4%, medium tillering ability. Leaves relatively large and nearly round, leaf surface wrinkles numerous and relatively deep, back pubescence relatively thick, leaf margin serrations deep and sparse, petiole insertion angle medium, stipules greenish-yellow, female buds reddish-brown. Raw fiber greenish-white, rust foot extremely short, no spots or defects, soft to the touch, gum content 26.8%, single fiber count 2472.6 count, can spin 80-100 count high-grade yarn, reaching premium quality indicators. Bundle fiber strength 4.92 gram-force/5Okg. Highly resistant to mosaic disease, relatively resistant to anthracnose.

The two-year variety comparison averaged 152.5kg per mu, an increase of 17.7% over the control Xiangzhu No. 2 and 12.8% over Xiangzhu No. 3; the provincial regional trial averaged 161.9kg per mu, an increase of 39.8% over the control variety Luzhuqing; field demonstrations and extension covered more than 60,000 mu, with yields all above 150kg per mu.

Region and techniques: 1. Sowing: 500g of seed can sow 1.0-1.2 mu of seedling bed, and can transplant to 15-30 mu of field; generally sown in March, aiming for sowing, transplanting, and harvesting in the same year; ramie seeds are very small, requiring finely prepared seedling beds. 2. Transplanting: seedlings can be transplanted when they grow to 6-8 leaves, generally planting about 6000 plants per mu, with wide-narrow row or equal row spacing, and sufficient organic fertilizer applied before planting. 3. Harvesting: generally the standard for harvesting is when the stems turn brown-black from bottom to top reaching 1/2 of the height; achieve quick peeling, quick stalk cutting, and quick fertilizing to promote the fastest possible growth of the next crop of ramie. 4. Winter cultivation: generally carried out after frost, including deep intertillage, heavy fertilization, and earthing up with soil cover; the quality of winter cultivation affects the ramie yield of the second year.
