Abstract:

Determining the genetic relationship between the species or genera is very important for genetic improvement and phylogenetic studies. Fifty one landraces of rice were evaluated for the estimation of genetic variation among the agromorphological characters. Fifty one genotypes used for the grain quality studies showed significant differences among grain quality traits. Heritability estimates were higher for morphological traits ranging from 45.8 to 99.9. Correlation analysis indicated that plant height had positive and significant association with panicle length, and grain weight. At genotypic level, kernel weight was correlated positively and significantly with maturity, grain weight, grain length, grain breadth and flag leaf angle. Path coefficient analysis indicated direct effect of grain weight followed by number of grains panicle-1  and grain length/breadth ratio. The grain quality studies revealed the better performance of Sarkele aman followed by Jhingasal and Annada with high values of panicle length, plant height, grain weight, number of primary branches panicle-1, number of grains panicle-1; Malliksal for higher values of grain length; Majhisal and Basmoti local with high values of number of primary branches panicle-1 and number of grains panicle-1.
