Abstract<\/strong><\/p>\n\n\n\n

A field experiment was conducted at Dmsrkho region, Latakia governorate, Syria, during two\nseasons 2017 and 2018.  Six genotypes of maize Zea\nmays<\/em> L. saccharat<\/em> were used in this study, i.e: Temptation,Target-A, Sucaria-1 and Sucaria-7- Merritt (USA), and (Faihaa) to study of\nthe  genotypic and phenotypic correlation\nand path analysis  of yield and its\ncomponents (number of grains per row, number of rows per ear, 100 kernel\nweight, ear length, ear circumference), to determine the most common traits of\nyield and to determine the\nappropriate selection\ncriteria evidence to improve\nSweetcorn. The study showed that the\ngenotypic correlations were higher in most studied traits. The study of genetic\ncorrelations were significant and positive in most traits, especially between\nthe fresh yield of the plant with the plant height (rg<\/sub>=0.57**), ear height (rg<\/sub>=0.53**), ear length (rg<\/sub>=0.69**(, ear circumference (rg<\/sub>= 0.83**), number of rows in per ear (rg<\/sub>=0.34**),\nnumber of grains per row (rg<\/sub>= 0.72**) and 100 kernel\nweight )rg<\/sub>=0.66**.( The results showed a high direct effect of the number of grains per\nrow )Genotypic\n0.55 and phenotypic 0.53), 100 kernel weight (Genotypic\n0.563 and phenotypic 0.451), number of rows per\near  (Genotypic 0.51 and  phenotypic 0.35( and plant height  (Genotypic\n0.113 and phenotypic 0.184(, on the individual plant yield because of their strong\ncorrelation with it. These traits can therefore be relied as selection criteria\nto improve grain yield in Sweet corn. The relative importance of the yield\nvariability was (58.67%) because of the fifth aforementioned traits, while the other\neffects on yield were (41.33%). These five traits are the most important traits\nthat affect the variation in yield in this study<\/p>\n\n\n\n

Key words:<\/strong> Sweet corn, Genotypic correlation, phenotypic correlation, genotypic path coefficient, phenotypic path coefficient.<\/p>\n\n\n\n
