Nohutta Cicer arietinum L. Gül-Çiçekli Mutasyonun Kalıtımı

Mutasyonlar, bitki türlerini de içeren canlı organizmalarda varyasyon yaratmak için en önemli varyasyon kaynağıdırlar. Bitkilerde varyasyon yapay mutasyonlarla artırılabilmektedir. Bu çalışma kültürü yapılan nohutta Cicer arietinum L. gül-çiçekli yapay mutasyonun kalıtımıyla ilgilidir. Erkek ve dişi organları olmayan gül-çiçekli nohut mutantı M2generasyonunda belirlenmiş ve kardeşleriyle birlikte tek bitki hasadı yapılmıştır. Gül-çiçekli mutantın kalıtımı, mutant ve ebeveyn ya da diğer genotiplerle döllenmenin olanaksız olduğu M3 generasyonunda açılan sıralarda çalışılmıştır. Sonuçlar gül-çiçeklilik özelliğinin resesif bir genle rs idare edildiğini göstermektedir. Bu çalışma kısırlıktan dolayı döllenmenin mümkün olmadığı durumlar için alternatif bir yaklaşımdır

Inheritance of Rose-Flowered Mutation in Chickpea Cicer arietinum L.

Mutations are the most important phenomenon in the living organisms including plant species due to creating variation. Variation in crop plants can be increased by induced mutations. The present study deals with inheritance of an induced mutation with rose-flowered in the cultivated chickpea Cicer arietinum L. . A mutant having rose-shaped flowers without male and female organs in the cultivated chickpea was isolated in M2 and harvested as a single plant with its sisters sibs . In M3, inheritance of the rose-flowered mutant was studied in the segregated rows because hybridization between the mutant and parent or the other genotype of the cultivated chickpea was not possible. Results indicated that the rose-flowered mutation was controlled by a single recessive gene rs . This study is an alternative approach on inheritance studies if hybridization is impossible due to sterility
