The correlation coefficients amongst the different characters at phenotypic and genotypic levels revealed that the number of spikes per
year yield and per plot had a significantly positive association with plant height, number of pseudostems per plant, number of florets/spike,
and spike length, whereas a significant positive correlation was observed with days to first harvest. Spike length had a positive association
with plant height, leaf length and width, number of pseudostems, and number of florets/spike, whereas its negative correlation with days
to first harvest was observed. The number of florets per spike had a positive association with plant height, leaf length and width, and
number of pseudostems, while its negative correlation was found with days to first harvest. Days to first harvest had a negative correlation
with all the traits observed in the present study. Plant height showed a significant and positive association with leaf length and width, and
number of pseudostems per plant. Spike length had a very high positive direct effect and the number of pseudostems per plant had a high
positive direct effect on the number of spikes per plant per year. The present findings showed that selection should be made on the basis
of spike length and number of pseudostems per plant which may have the highest positive direct effect considering other traits while
making improvement in orchids for number of spikes per plant per year.
