Response of ems and colchicine on genetic variability, heritability and genetic advance in bhendi (<em>Abelmoschus esculentus </em>(l) moench) varieties of MDU 1 and Arka Anamika

Abstract:
Bhendi (<em>Abelmoschusesculentus</em> L.) is major vegetable crop in tropical and subtropical regions of the world. Mutation induction has been accepted as a useful tool in plant breeding programme to provide more variability. The seeds are bhendi varieties MDU 1 and Arka Anamika were subjected to the chemical mutagens. The investigation using ethyl methane sulphonate (EMS) and colchicine in various concentrations which were fixed based on LD<sub>50</sub> value. The yield and its component traits were recorded in M<sub>2</sub> generation. The PCV and GCV were more for number of branches per plant, number of notes per plant, fruit girth, fruit weight, and fruit yield per plant indicating the release of micro mutation for these characters. High heritability coupled with genetic advance for fruit yield per plant was observed in 0.8 percent EMS treatment in MDU 1 variety. This indicated that variability induced by these treatments in these variety is highly heritable and additive in nature and hence selection will be effective
