CORRELATION AND PATH ANALYSIS IN MEIOTIC CHROMOSOME BEHAVIOUR IN SOME EXOTIC PAPAVER SPECIES

Published on

orrelation and path coefficient analysis of cytological characters was done in 21 entries of
exotic Papaverspecies. Abnormalities at metaphase I, anaphase I, telophase I, meiotic index
and pollen fertility showed highly significant correlations between them. Path analysis
revealed only negative direct and indirect effects. Abnormal cells at M I, A I and T I had
greater magnitude of negative direct effects on meiotic index and pollen fertility with
substantial involvement of abnormal cells at A I.
 

Keywords: Papaver somnifernm, P. setigerum, correlation coefficient, path coefficient, meiotic abnormalities.
