     Резюме
 
The article examines the correlation and regression relationships between the weight of the first cob, as one of the main commercial parameters in sugar maize and some other main indicators in the medium-sized hybrid corn Knezha - su 2, which can form more than 1 standard cob of plant - an average of 1.6 pieces. It was found that the weight of the first cat correlates differently in degree and character with the indicators tested. The highest, positive and proven correlations and regressions are between the weight of the first cob and the diameter of the cob. The average correlation coefficient for the hybrid is r = + 0.71 and is reliably proven at the highest level. The regression coefficients for Knezha su 2 are respectively R X / Y = + 8.0 and R Y / X = + 0.06. Between the weight of the first cage and the number of cobs, the correlation dependence is negative but not strong. The negative correlation for Knezha 2 su is r = - 0.40. The correlation between the weight of the first cat and the height of the plants is the lowest and least reliable. This should be taken into consideration when forming the crops, because the high plants in the sugar corn are easier to lay down.
