Abstract:

In the present investigation efforts were made to identify the distinct, uniform and stable morphological characters and molecular markers between NILs developed for SUB1 in background of Pushyami (MTU 1075), Amara (MTU 1064), SALTOL in Cotton dora sannalu (MTU 1010) and lodging resistance in Swarna (MTU 7029) and Indra (MTU 1061) and their respective recurring parents. Rice productivity is limited by major abiotic stresses. Incorporation of stress tolerance gene/Qtls into popular varieties is one of the breeding strategies to combat adverse effects of climate changes. Characterization of rice genotypes is necessary for identification and protection of varieties under PPV. Results of molecular characterization showed genetic diversity among 24 entries. PIC value ranged from 0.08 (RM 6006) to 0.70 (RM 2229). Cluster analysis grouped 24 entries into two distinct clusters at similarity coefficient of 33 %. The results revealed that grouping of clusters using molecular markers is in accordance with parental ancestry and morphological traits. Graphical genotyping revealed that genome recovery of recurring parent in developed NILs ranged from 75.1 % (MTU 2546A-12-18-1) to 96.4 % (MTU 2336-70-46-25-44). Most of the agro morphological characters were found to be similar between near isogenic lines and respective recurrent parent.
