Abstract

Study of GENETIC DIVERSITY of RICE is very important for RICE breeders. In this study 64 genotypes for 14 agronomic traits were evaluated. Phenotypic variation coefficients of some of traits were high which showed essential variation in this traits. Principal component analysis detected 6 components which explained 74.66 percent of the total variations. The first component was related to generative traits such as number of spiklet per panicle, number of full grain per panicle, date of 50% flowering and length of panicle. In the third component, the date of complete maturity with -0.730 has negative effects on yield. Correlation analysis of MORPHOLOGICAL TRAITS indicated a negative and significant relationship between early maturity and plant height, which showed early maturity cultivars, had higher plant type. Results of stepwise regression analysis for early maturity indicated that three traits such as date of 50% flowering, number of full grain per panicle and plant height showed higher variation and explained 54.3 percent of total early maturity variations. All traits were classified into 2 groups, by cluster analysis and traits belonged to early maturity classified as a sub-group. Genotypes were classified into 4 groups by using method of Wards minimum variance and squared Euclidean distance. Native cultivars from the view point of early maturity and yield components had useful information for RICE breeding.
