Genetic diversity analysis of 19 coloured and white rice genotypes were conducted using 14 Simple Sequence Repeat (SSR) and 21 Insertion Deletion (INDEL) markers. Among them, polymorphic results were obtained for 9 SSR and 12 INDEL markers. The PIC values ranged from 0.36(RM484) to 0.78 (RM 167) and 0.50 (R9M20) and 0.81 (R9M10) for SSR and INDEL markers respectively. In the case of both SSR and INDEL markers highest genetic diversity was observed between Krishna Kamod (White pericarp) and IRST 1 (Red pericarp) whereas least genetic diversity was observed between Lal Kada (Red pericarp) and Krishna Kamod (White pericarp). However, it was also found that brown, black and red pericarp share more similarity among themselves. It was also observed that INDEL markers reveals greater diversity among the genotypes as compared to SSR markers which was indent from the low average similarity index observed in the former. On the whole INDEL markers were found to be more efficient than SSR markers for diversity analysis.
In the present investigation, three bottle gourd varieties i.e., AB-1, Pusa Santusti and Pusa Navin were subjected to seven different osmopriming chemical treatments of KNO3 at three storage periods. The data obtained from various observations were analyzed by using Factorial Completely Randomized Design (FCRD). The better seed quality was recorded when the seeds stored for 3 months under ambient condition. Among the studied varieties Pusa Navin stored for 3 months and treated with 150 ppm KNO3 recorded significantly highest seed germination as well as other seed quality parameters. The results depicted that the seed quality of bottle gourd was significantly influenced by varieties, storage periods and osmopriming treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
