Impact of Agromorphological Quantitative Traits Towards Divergence of Rice (Oryza Sativa L.) Landraces

Abstract

Background Rice Landraces has a never deniable Importance in agriculture because existing variety improvement and future breeding program depends on the desirable genes present in the landraces only. Landraces can be selected on the basis of various morphological parameters. So, assessment, analysis and documentation are very much essential. Methods In this review, authors searched various different databases to study the morphological diversity and relationship within the landraces. Observational and Interventional studies of Rice landraces and morphological markers are included in this review studies. Results In an efficient breeding technique, selecting important characters on the basis of detailed information and association patterns between the yield and yield related components is very significant for crop up-gradation. To understand the genetic variability between enviable landraces, presence of genetic divergence in the landraces is essential and it guides to successful exploitation of landraces in breeding program. In this study it is revealed that there are significant interrelationships among yield and yield related characters where the yield related traits applied their direct and indirect effect through other traits for improving grain yield/hectare. Conclusions An extensive amount of variation was recorded for maximum characters within the genotypes studied which indicate that the selection on the basis of these characters is imagined to be effectives. Characterization of rice landraces expressed distinctiveness among the rice landraces. It is very much important for utilizing the proper characteristic in breeding programmes and also important in the present time for protecting the landraces of rice.
