Abstract:

The present investigation is carried out to study the correlation and path analysis in fifty six high iron and zinc genotypes of rice (Oryza sativa L.). Character association studies revealed that the characters grain yield per plant showed significant positive association with number of productive tillers per plant, panicle length, number of filled grains per panicle and grain iron concentration. Hence, selection for these traits can improve yield. Path coefficient analysis revealed that the traits 1000-grain weight, numbers of filled grains per panicle, number of productive tillers per plant, grain iron concentration, grain zinc concentration, days to 50% flowering and plant height were directly influencing the grain yield per plant. Hence, these traits were considered as important attributes in formulating selection criterion for achieving desired targets.


Keywords: Rice, Correlation coefficients, Path coefficient analysis.
