Selection of improved rice lines through the comparison of agronomical characteristics of M4 mutants from Tarom Mahali, Hasani and Anbarbo varieties
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 1
Abstract
The production of suitable varieties is possible for the cultivation in paddy fields through the recognizing of the genetic resources of plant materials. In order to study of M4 mutants from Tarom Mahali (66 No.), Hasani (38 No.) and Anbarbo (29 No.), their selected seeds were planted by one panicle and seeds of check varieties, Tarom Mahali, Hasani and Anbarbo were planted in 2 square meter on nursery. The design was carried out as Augment design with 6 block and check varieties were randomly take placed in each block. The transplanting was done by one seedling with 25×25 densities in 1 square meter. For each mutant and check were measured characteristics of the number of flowering day, plant height, panicle number per hill, yield and yield components in flowering and ripping stages. The results showed that the mutants were early- maturity related to check varieties. There was diversity for plant height trait, but most of mutants were decreasing 10-30 percent in plant height compared to check. There was diversity between yield components but all of most were same with check varieties. The increasing yield of selected mutants was 10-27 percent. The cluster analysis of mutants from Tarom Mahali, Hasani and Anbarbo varieties were grouped them to 5, 3 and 4 groups respectively. The most of selected lines were placed in group of 3 and 4. The 8 lines with higher yield, however, 12 lines of earlymaturity and short plant height with same yield were selected as well.
