Character association for yield components
-
A field experiment was conducted to estimate the genetic variability, trait association and path coefficient analysis among the Indian mustard genotypes during rabi, 2019. Analysis of variance revealed the mean sum of squares due to genotypes was highly significant for all the characters studies indicating the existence of ample variability among the genotypes studied. The high GCV and PCV observed for number of siliquae per plant and secondary branches per plant indicated the influence of environment on the expression of these characters were at minimum level.

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 .

The present investigation was undertaken in 23 genotypes of blackgram [Vigna mungo (L.) Hepper] to study the genetic variability parameters, correlation and path analysis during Kharif, 2019 in Randomized Block Design with three replications. The observations were recorded for fourteen quantitative characters to study genetic variability, heritability, genetic advance, correlation and path analysis.

Black gram is a major pulse crop and a good source of proteins and minerals. Genotypic correlation and path coefficient analysis were used to determine the effect of various traits as components of seed yield in fifty black gram genotypes. Genotypic correlations were recorded higher as compared to corresponding phenotypic correlations for majority of the traits under study indicating that there was an inherent association between these characters at genotypic level.

The present study was undertaken with the objective to determine the degree of association between yield and it`s component characters and their direct, indirect effects on grain yield in aerobic rice. Twenty two aerobic genotypes with 4 check varieties were evaluated for identifying their efficiency with respect to 10 yield and yield attributing traits.

Sixty four landraces were evaluated for 10 yield and its component traits. Analysis of variance showed significant difference among the genotypes to all the characters under both control and low-moisture stress condition. Environmental influence was meagre on expression of characters as evidenced by narrow gap between GCV and PCV for most of the characters.

An experiment was conducted with 32 cultivars of dahlia (Dahlia variabilis L.) to study correlation and path analysis among the yield attributing traits and their effect. Correlation among component characters showed that flower yield per plant had a highly significant positive genotypic correlation with leaf area index (0.617), crop duration (0.771), flowering duration (0.800), tuber weight (0.668) and change in fresh weight at day 3.

The sesame germplasm consisting of thirty three accessions were assessed for the extent of variability, degree and direction of character association among yield and its contributing traits and the direct and indirect effects of various components on yield. Analysis of variance showed significant differences among the genotypes for almost all the characters studied. High and moderate phenotypic and genotypic coefficients of variation (PCV and GCV) were noticed for most of the yield contributing characters.
