CORRELATION STUDIES IN UNUM USITATISSIMUM-II. EFFECT OF MORPHOLOGICAL GROUPING OF TYPES ON THE CORRELATION COEFFICIENTS RELATING TO YIELD AND SOME OF THE COMPONENTS OF YIELD

Published on

YIELD is the ultimate criterion which a plant breeder has always to keep in view in
his attempts to evolve improved types of any crop plant. However, yield itself, as is
well known, is not a unitary character but is the result of the interaction of a number of factors inherent both in the plant as well as in the environment in which the
plant grows.
It, therefore, becomes difficult to evaluate or select for this complex
character directly. Recourse must then be had to more indirect methods such as
determination of the association existing between other, less variable, plant characters
and yield. Selection pressure may then be more easily exerted on any of the
characters which show close association with yield. The existence of association is
usually determined by studying the correlation existing between different characters
and the quantitative character under study.
