Abstract To optimize the testing methods and grading standards for quantitative characteristics of Okra,this
experiment took 35 Okra varieties as research objective;observed and compared 2 quantitative characteristics,
including plant height and main stem diameter by different measuring methods;and graded 12 quantitative traits
by the least significant difference method. The results indicated that considering the consistency of within one test
area and convenience for operation,natural plant height and diameter of middle main stem should be measured.
Based on the existing material,we classified the depths of crack fluting leaves into 9 grades,and unequal grading
was suitable for measuring the length of matured fruits.
