CORRELATION AND DISCRIMINANT FUNCTION ANALYSIS OF SOME SELECTED CHARACTERS IN FINE RICE (Oryza sativa L.) AVAILABLE IN BANGLADESH (Pages : 30 - 35)

A field experiment was conducted with 30 fine rice genotypes for correlation and discriminant function analysis of some selected characters. A remarkable variation in plant characters and yield performance was noticed among the fine rice. Genotypic correlation coefficients indicated a fairly strong inherent relationship among the characters. A total of the 31 selection indices along with genetic worths and relative efficiencies over straight selection were estimated the five single character selection indices, grain yield offered maximum genetic worth (12.05). The two character combination function a substantial gain of 171.45% was observed when effective tillers/hill was selected together with 1000-grain weight. It is obvious that the index, I245 accounted a profitable efficiency (217.18%) as compared to other three character functions studied and the four character index, I1245 appeared to be highly beneficial over straight selection. However, the tedious approach, I12345 might be adopted while attention of a breeder is solely engaged for increasing grain yield in fine rice. Download
