VARIABILITY PARAMETERS OF SOME MORPHOLOGICAL ATTRIBUTES AND PRODUCTION OF SWEET CORN
Abstract
Yield and its stability components are major requirements for new sweet corn hybrids.The emphasis on improving and increases of yield for sweet corn new hybrids is due to climate change in recent years. Biological material used in this stage was represented by seven sweet corn hybrids, of which six are Romanian and one foreign. Among the analyzed properties, the diameter of the cob has the lowest values regarding coefficient of variation, indicating genetic stability, a variation indicating the pronounced genetic stability of this characteristic and the high contribution of the genotype in the phenotypic expression of this characteristic. The simple hybrid Estival M has the lowest fluctuations in the coefficient of variability (CV%) from year to year of 3.77 and 3.93, respectively. Other charactheristics that were analyzed were represented by: plant height, weight of the sweet corn cob, number of grains (berries)/cob and the length of the cobs.
