annot. The number of rows of corn kernels, grown in pairs, must be an even number. According to a journal article published in Nature in 1911 on the genetic characteristics of maize row numbers (Inheritance of Row-numbers in Maize Ears), we can know that the row numbers of different maize varieties can vary from 8 to 24. The ranks vary, and even more. In the same corn variety, different row numbers will also appear. Some varieties have 8, 10, and 12 rows; some have 12, 14, 16, and 18 rows; some varieties have 18, 20, 22, and 24. Row, and some varieties have more variation in the number of rows
. Therefore, it is impossible to judge whether it is genetically modified corn based on the number of rows of corn kernels alone (ref. 1). What is genetically modified corn? Genetically modified crops refer to changing the genetic sequence of plants under all conditions set in the laboratory, so that the plants show the characteristics we want, such as: drought tolerance, pest resistance, or sweet taste, fruit yield Wait more. According to the statistics of the International Service for the Acquisition of agri-biotech Application (ISAAA), as of June 2018, there were 29 varieties of 498 genetically modified Shadow Making crop lines approved for cultivation in the world. Among them, genetically modified maize accounted for 229 cases (ref. 2).
The characteristics and purposes of genetically modified maize mainly include 6 types: Abiotic Stress Tolerance: drought resistance, cold resistance, flood resistance, etc. Growth or yield modification (Altered Growth/ Yield): adjust the growth process and quantity, etc. Herbicide Tolerance: After spraying various herbicides, it can still survive without affecting yield, low pesticide residues, etc. Insect Resistance: Anti-insect, anti-virus, anti-fungal, anti-bacterial and other diseases Modified Product Quality: Improve fruit plumpness, sweetness, etc. Pollination Control System: Modify the reproductive pro More about this source textSource text required for additional translation information Send feedback Side panels
