ESTIMATES OF INTER- CHARACTER ASSOCIATION OF EASTERN COTTONWOOD (POPULUS DELTOIDES. BARTR) CLONES

Abstract

Forty-nine exotic and indigenous clones of Poplar were evaluated for eight morphological traits to identify the
prominent clones of Poplar. At both 2 and 3 years of age diameter showed significant and positive phenotypic
correlation only with plant height (0.5979) and (0.5603), respectively. Similar trend was observed with other
parameters such as, at the 2 years of age Leaf lamina length showed significant and positive phenotypic correlation
with petiole length (0.5447), total leaf length (0.8733), leaf width (7488), L/B ratio (0.4927). Same trend was
observed at the 3rd year with Leaf lamina length being phenotypically significant and positively correlated with
petiole length (0.5447), total leaf length (0.8733), leaf width (7488), L/B ratio (0.4927). Petiole length at 2 and 3
years of age was significant and positively correlated with total leaf length (0.8217) (0.8737), leaf width (0.7517
(0.5156) and L/B ratio (0.3868) (0.7317) respectively. Almost similar trend has been observed at genotypic level
but with a higher degree.
