Özet

This investigation was carried out to study the inheritance of stem, leaf and capsule hairiness and number of capsules per leaf axil in sesame. For hairiness, Muganli-57 (female) which is hairless was crossed with ACS 82 (male) with high hairiness on capsules, leaves and stem. For number of capsules per leaf axil, Muganli-57 (female) with one capsule per leaf axil was crossed with ACS 114 (male) and ACS 139 (male), which were providing three capsules per leaf axil. The results in the F-1 generation of the cross made for hairiness revealed that hairiness in sesame was controlled by a single dominant gene and it was dominant over hairless. Similar result was obtained for the crosses of number of capsules per leaf axil that one capsule per leaf axil character was dominant to three capsules and this character was controlled by one single gene. Chi-square values obtained for all the crosses in F-2 progeny showed a good fit for a monogenic inheritance with the F-2 phenotypic ratio of 3:1. Three capsules per leaf axil and hairiness are the important characters for providing more seed yield and natural defense mechanism for some biotic and abiotic factors, respectively. Therefore these two characters could be assessed as a part of ideal plant type. The information presented in this investigation was beneficial for the genetic improvement of sesame and reaching to appropriate plant type.
