An experiment was conducted during kharif 2013 and 2014 in North Coastal Zone of Andhra Pradesh at Agricultural Research Station, Ragolu, Srikakulam district to study the genetic parameters like variability, heritability, genetic advance, correlation and path analysis for fibre yield and eleven component traits in a set of 60 genotypes of roselle (Hibiscus sabdariffa L.). Phenotypic as well as genotypic coefficients of variability were high for the important productivity characters like green weight (leafless) plant-1 , dry stick weight plant-1 and fibre yield plant-1 .

Statistical correlation coefficient is a measure that denotes the magnitude and direction of interrelationship between any two casually related variables. The information on the genotypic and phenotypic interrelationship of cane yield and sugar yield with their component characters interest would be of immense help to the sugarcane breeder. The character association will also help in the selection of superior genotypes from divergent population based on more than one interrelated characters.

Seed cotton yield and fibre quality traits are governed by polygenes and these traits are highly influenced by the environment. Hence, selection merely based on yield is not effective. In order to enhance the yield potential of the cotton varieties, knowledge on the direct contribution of different characters to yield would be highly important for formulating a selection programme.

An investigation was carried out using 20 opium genotypes, to study character association between fourteen characters and their direct and indirect effect on seed yield and latex yield independently. Association study indicated that seed yield per plant had significant positive correlation with diameter of main capsule (0.60) and latex yield per plant (0.60). Whereas latex yield per plant had significant positive correlation with days to 50 per cent flowering (0.53) and seed yield per plant (0.

The present study emphasized on determination of the nature and magnitude of variability, heritability and genetic advance on yield and yield attributing characters in 19 potato genotypes harvested on different date. The estimation of correlation co-efficient among the characters along with their direct and indirect effect on yield is necessary to carry out proper selection on the basis of the traits. Wide ranges of variation have been observed for all the traits both in early and late harvesting situation.

The research carried out during 2010 at Saffron Research Station Pampore, SKUASTKashmir to investigate the yield relationships between yield and some yield related components of fifty clones of saffron (Croccus sativus L.) by using path coefficient analysis. All the clones were replicated thrice with plant geometry of 20×10cm. Observations were recorded on 10 randomly selected and tagged competitive plants for morphological, physiological, floral and corm attributes.

A study was conducted to assess the induced genetic variability, interrelationship among yield components and their direct and indirect effect on yield. Thirty six genotypes of linseed (Linum usitatissimum L.) were evaluated in Randomized Complete Block Design with three replications. Substantial amount of genetic variations were observed with low influence of environment indicated consistence performance of the genotypes.

The efficiency of a breeding programme depends mainly on the direction and magnitude of the association between yield and its components and also the relative importance of each factor involved in contributing to grain yield. The path analysis provides an effective measure of direct and indirect causes of association and depicts the relative importance of each factor involved in contributing to the final product.
