Abstract

Rice (Oryza sativa L.) is a very important commodity. The nutritional content in rice makes rice a very important commodity to meet food needs. One of the efforts that can be made to increase rice productivity is to create new superior rice varieties that have high yields. This study aims to examine and determine the varied morphological characteristics of the new superior varieties of rice, and determine how close the kinship relationship is between 51 new superior varieties of rice (Oryza sativa L.) and determine the advantages of each variety. This research was conducted at the Experimental Garden of the Indonesian Rice Research Center located in Sukamandijaya Village, Ciasem District, Subang Regency, West Java. The time for conducting the research was carried out in September 2021-March 2022. The research method used was a descriptive method, with 51 treatments of new superior rice varieties. Each treatment was repeated 3 times so that there were 153 experimental units. Each observational data on morphological characters of 51 superior rice varieties (Oryza sativa L.) was analyzed by clustering using the UPGMA method with NTSYS 2.02i and 2.11a software. The results showed that the results of the cluster analysis formed 6 main groups at a similarity coefficient value of 0.72 (72%). There are 7 closest kinship relationships and have the farthest kinship in inpari 1 and Inpago 9 varieties. Keywords : Characterization, Morphology, New superior varieties, Clustering, Rice

Abstract

Differences and similarities in morphological characters in rice plants can be distinguished through characterization activities. Morphological characterization needs to be carried out to identify the superior characters that appear, especially characters related to the growth and development of rice plants which can increase the yield potential of rice. The results of the morphological characterization can be used to determine the close kinship and genetic distance between plants. This study aims to determine the kinship relationship and genetic distance formed in several selected superior varieties of rice plants. The research was conducted at the Experimental Garden of the Sukamandi Rice Research Center. The research method used is descriptive experimental method with a treatment of 44 varieties of rice, repeated 3 times. Observational data were analyzed using Ntsys 2.02 and 2.11 software with the UPGMA method. The results showed that several selected high yielding varieties had similarities in several morphological characters such as leaf width, leaf angle, leaf neck color, leaf midrib color, leaf tongue color and leaf tongue shape. The resulting similarity coefficient is 0.75 and seven groups with close kinship are formed. The genetic distance formed in several selected superior varieties of rice plants has a narrow diversity with a value of 0.25. The results for both parameters indicate that the resulting genetic diversity is small. This cannot be used as a cross parent but can be used as genetic material which is re-analyzed to increase its diversity.

Abstract

Rice (Oryza sativa L.) is known to have a very diverse genetic diversity. The target of rice variety improvement is to produce new varieties that have superior traits in accordance with the development objectives in each typological region. This study aims to determine the level of similarity formed in a number of new superior varieties. The method used is descriptive experimental, with 51 treatments, namely new superior varieties, repeated 3 times so that there are 132 experimental units. Each agronomic character observation data was analyzed by clustering using the UPGMA method. The analysis used NTSYS 2.02i and 2.11a software. The results showed that the genetic variability of 51 new superior varieties of rice (Oryza sativa L.) has a similarity coefficient value of 0.81 based on clustering analysis. This shows a high level of similarity of genetic variability, however, the clustering results form 5 main groups with genetic distances ranging from 0.0000 - 0.5593.  Keywords: genetic variability, seed morphology, new improved varieties, clustering.
