Variation of early maize cobs with actual morphological characters

Being in full swing, studies on the variability of morphological characters, along with biochemical and molecular features, are considered very useful for the improvement of new maize hybrids. Rich genetic dowry and maize crop conditions lead to the characteristic expression of plant morphology. In the case of maize, the hybrid Surterra, some new directions have been found, which has recently been improved, with new morphological characters tendencies. Thus, the cobs had an average length of 17 cm, a thickness of 4 cm and weighed 159 g. The number of grains on the cob was 451, weighed 127 g, and the one thousand grains was 280 g. The cobs had 14 rows of grains, 32 grains/row, and the grain/cob percent was 81%. The grains of this hybrid were 10 mm long, 9 mm wide and 4.6 mm thick. Between the analyzed characters of the cob were mostly positive correlations. Grain percent/cob correlated negatively with most characters, while grain thickness correlated insignificantly with other attributes. The new, early-grading hybrid (FAO 250 group), cultivated, has shown a good adaptability to a new and performing agriculture.
