CLUSTERING OF BASMATI RICE MUTANTS BY METROGLYPH ANALYSIS

 MUHAMMAD RASHID^*, AKBAR ALI CHEEMA AND MUHAMMAD ASHRAF

Abstract: Deviations observed by Metroglyph method regarding the number of clusters formed, number of genotypes in each cluster and superimposition of the genotypes within the cluster pointed out the precision and refinement of the technique in studying the germplasm collection. It is noted that through induced mutation genetic improvement for yield and yield components is possible. Metroglyph scatter diagram provided the possibility of 11 clusters of rice genotypes. Cluster-I and cluster-II possessed the highest index scores i.e., 66 and 56 respectively on morphological basis. On the basis of this clustering, it can be interpreted that mutants between cluster-I and cluster-II is expected to give better types after hybridization
