Abstract

An experiment was conducted to study 14 mungbean genotypes for 19 morphological traits as per DUS guidelines at Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) India, during Kharif 2020 as well as in summer 2021. All the genotypes were grown in randomized block design in a replication of three in the seasons mentioned above. Morphological traits were recorded as per crop DUS guideline approved by PPV & FR, New Delhi. Maximum morphological variability was recorded in leaf vein colour, colour of petal, leaf colour, leaflet lobe, pod colour, pod curvature, seed lusture and anthocyanin colouration. The distribution frequency of the traits like seed size (7.69%) followed by colour of pre-mature pods (7.14%), leaf vein colour (7.14%) and anthocyanin colouration (7.14%) was very low. Genotype SL 668 was reported as diverse mungbean variety dominated with green with pigmented suture in pre mature pod colour and also dominated with large seed size. The trait anthocyanin colouration wa

Conclusion

The study highlighted the importance of introducing new material in the breeding programmes to broaden the genetic base of the crop. Thus, characterization of elite improved lines holds an important significance in the identification of lines and their registration with PPV&FRA and maintenance of line having the information of genetic base. Lines found with unique traits and present only in few of the genotypes will be of great importance for the development of morphologically diverse breeding populations. These lines with unique morphological identity will be considered as a varietal marker in the seed production chain to maintain the genetic purity of the variety. These traits may also be useful when varieties may mix and purelines can easily beisolated very easily by normal selection method.
