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

<\/p>

The experiment was conducted at Hama Agricultural\nResearch Center during 2016,\n2017 and 2018 seasons to\nstudy the heterosis according to the best parent and inbreeding depression in F1<\/sub>\nand F2<\/sub> of the resulted hybrids from top cross<\/a>\nprogram among ten parents of upland cotton. Analysis of variance indicated high\nsignificant differences among the genotypes for all characters except sympodial\nbrunch number in F2<\/sub>. Estimation of heterosis showed significant\npositive values in some F1<\/sub> hybrids that reached 20.18% sympodial\nbrunch number, (44. 74%, 44.30%, 47.06%, 65.00%) opened bolls number and (39.07%, 44.18%) seed cotton yield which may\nrefers to variance of parents in genetic factors that control these traits.\nHeterosis in F2<\/sub> excelled F1<\/sub> which indicated to the\ntransgressive segregation. Heterosis accompanied with positive inbreeding\ndepression values indicating to dominance effect. Also, negative values of\ninbreeding depression were noticed in some hybrids because of F2<\/sub>\nexcellence to F1<\/sub>. To confirm the superiority in these hybrids, it is\nrecommended to be tested in large-scale trials.<\/p>\n\n\n\n
