 ABSTRACT

A hundred landraces of rice (Oryza sativa L.), from core group genotypes collected from different parts of Chhattisgarh, were characterized following the guidelines from the Protection of Plant Varieties and Farmers' Rights Authority, GOI. Hundred rice accessions were planted in a randomized block design (RBD). The data were recorded on 32 different agro-morphological traits (20 qualitative and 12 quantitative). The study revealed a high degree of variation in agro-morphological traits of rice accessions with a Shannon diversity Index ranging from 0 – 1.223 with a mean of 0.548. The highest diversity index of 1.223 was observed for flag leaf attitude of the blade. The coefficient of variation was more than 10 % for most of the characters; Correlation coefficients showed that all the traits were highly correlated with each other. Grain yield per plot showed a highly significant and positive correlation with biological yield per plot (r= 0.512) and days to 50% flowering (r= 0.299). Therefore, these characters emerged as the most important associates of grain yield in rice. The genetic potential of the mentioned accessions for the desired traits can be utilized in future rice breeding programs to get promising results.
