Correlation analysis of early maturity of corn hybrids by FAO
Abstract
Carried out correlation analysis of determination the early maturity of hybrids by number of FAO when growing corn in the central zone of Belarus according to the numbers of days from germination to flowering of a cob of corn and leaves on one plant, dry matter content in the plant and moisture in grain during harvesting. It is shown that the last two indicators give a more accurate result regardless of the weather conditions of the year. A discrepancy was found in the value of the number of FAO assigned by the originators of hybrids, so for an adequate assessment of precocity, this should be done in the field of commercial production. Depending on the intended use, a hybrid can have a different the number of FAO, especially in relation to hybrids with a low proportion of grain in the dry matter yield.
