ABSTRACT

Eighteen genotypes of Kenaf including five F1s and eleven genotypes of Mesta along with three cultivated varieties were grown in pots at central station of Bangladesh jute Research Institute (BJRI) during August-September, 2021. A total of 226 crosses in Kenaf and 38 crosses in Mesta were made. Among them, 214 (191+23) crosses from 75 and 13 different cross combinations were successful in kenaf and mesta, respectively.

Key words: Hybridization, genotypes, kenaf, mesta.     

 

Introduction

 

 

Plant breeding is a mechanism of changing the characters of plants for getting desired characteristics. It is being used to upgrade the quality of products for the benefit of human being (Hartung and Schiemann, 2014). Classical plant breeding means crossing or hybridization of pure lines, followed by artificial selection to get plants with desirable traits of higher yield, nutrition and resistance to diseases (Bauman and Crane, 1992). It helps to create recombinant by accumulating desirable genes for both qualitative and quantitative characters from diverse parents (Kar et al., 2009). Through hybridization, it is therefore, possible to combine the desirable characters in a parent and to select superior progeny for varietal improvement program (Buerkle et al., 2013; Zhou et al., 2012). So, the hybridization program has been undertaken with 18 genotypes of Kenaf and 11 genotypes of Mesta including their checks for creating variability and to combine the desirable traits in a parent. Development of quick growing, short duration and stress resistant high yielding variety has been given the highest research priority under the context of global climate change. Genetic improvement through incorporating stress adaptive traits into good agronomic background is being duly emphasized in the variety development program.
