How is the Yumai 66 wheat variety?

It is a 1BL/1RS translocation line bred by the Yudong Crop Variety Exhibition Center of Henan Province and the Institute of Genetics of the Chinese Academy of Sciences through distant hybridization using the hexaploid triticale variety MZALEONDBA-TR from the Black Mexican International Maize @#@245@#@ Improvement Center as the female parent and Yumai 2 as the male parent (pedigree number (84) 184), and then through a second distant hybridization using the F6 generation 84 (184) 1 hexaploid triticale intermediate material as the female parent and the 90-selected line as the male parent.

It is a semi-winter, medium-late maturing variety. The growth period is 226-230 days. The plant type is compact, the stem is thick, the leaves are held upright, ventilation and light transmission are good, the leaf functional period is long, the plant appearance is clean and neat, and it is resistant to dry hot wind. The grain is oval and vitreous. It has good comprehensive disease resistance and is highly resistant to leaf rust and powdery mildew. It is moderately susceptible to sheath blight and stripe rust. However, the edge-row advantage is small, and the tillering-to-spike rate is low. Under ordinary cultivation conditions, the number of spikes per mu is somewhat low and it matures somewhat late. Crude protein 14.9%, wet gluten 33.5%, sedimentation value 33.8 ml, water absorption 60.54 ml/100 g, development time 5.8 minutes, stability time 8.4 minutes, evaluation value 62, bread volume 875 cm3, area score 88.4, reaching the strong-gluten flour standard. It is suitable for planting in the early-to-mid cropping season in the medium- and high-yield areas of the central and northern parts of our province. In cultivation, measures such as narrowing row spacing, increasing sowing width, increasing seeding rate, and shifting nitrogen fertilizer later should be adopted, and the yield can reach more than 1,000 jin.
