Abstract:
The forty five genotypes of Aromatic Rice were studied for genetic divergence .The observation were recorded on thirteen quantitative and three cooking quality characters. All the characters showed highly significant differences among the genotypes for all the characters, indicated that appreciable amount of diversity was present among the genotypes. The VDNGS-12 for grain yield per plant, straw yield per plant, VDNGS-19 for early flowering , L: B ratio, kernel length after cooking, amylase content, VDNGS-25 for productive tillers per square meter, 1000 grain weight, grain yield per plant, VDNGS-30 for productive tillers per plant, productive tillers per sq.m, 1000 grain weight, grain yield, amylase content, VDNGS-31 for L:B ratio kernel length after cooking, VDNGS-36 for number of seeds per panicle, 1000 grain weight, VDNGS-44 for number of tillers per sq. m., grain yield per plant were found to be superior genotype on the basis of per se performance.
The 45 genotypes were grouped into 10 clusters and the clusters I, II, IV, V and VI contained 21, 4 , 2, 8 and 5 genotypes, respectively. While, the clusters III, VII ,VIII, IX and X were monogenotypic. D² analysis revealed that there was a wide diversity between the genotypes. Suggesting that the genotypes may provide large source of variation under breeding programme. On the basis of per se performance and divergence classes the following genotypes were suggested for further breeding programme, viz., VDNGS-4, VDNGS-12, VDNGS-19, VDNGS-25, VDNGS- 30, VDNGS-31, VDNGS-20, VDNGS-44, For improvement of yield and yield components in Aromatic Rice.
