STUDIES on association between various characters in cotton have  resulted  in the establishment of correlation between yield and some of the important economic characters like lint outturn, staple-length etc. (Dunlavy, 19?3 ; Griffee, Ligou and  Brannon,  1929;  Stroman,  1930,  1945;  and  others).  However, since yield is composed of a number of components, selecting for yield should also take into consideration all these characters. The relative con.tribution both direct and indirect to yield, of each of  these  characters,  the  interactions  between them and also linkage among them can be examined by the path coefficient analysis. Originally proposed by Wright (1921)  such  analysis  has  recently been profitably employed to assess the importance of various yield components by many workers—Dewey and Lu (1959) in crested wheat grass, Ramanujam and Rai (1963) in Brassica and Melak, Pickett and Davis (1965) in Teff grass. The methods of application of this method of analysis have been discussed  by  Li (1948). The present study on yield in cotton (Gossypium hirsutum L.), takes into consideration six characters as contributors to or causes of yield.
