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.

Horse gram is highly proteinaceous important food legume crop. The present study was conducted at IGKV, RMD CARS, research and instructional farm Ambikapur, during Kharif2019 using 24 genotypes of horse gram. The observation was recorded for eleven characters viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, pod length, number of seed per pod, 100 seed weight, seed yield, biological yield and harvest index to study the correlation and path coefficient analysis.

The present investigation entitled, Phenotypic and Genotypic path coefficient analysis Studies in Chickpea (Cicer arietinum L.) was conducted at Agricultural Research Station, Badnapur, Dist- Jalna (VNMKV, Parbhani) ( M.S.) during Rabi season of 2019-20. The exploration of genetically variable accession or genotypes is the key source of germplasm conservation and potential breeding material for the future use. The highly divergence group of cultivars provides an opportunity to breeders for developing superior and new varieties considering their quality traits for direct commercial utilization.

Thirty mungbean genotypes were evaluated for the estimation of genetic variability, heritability, genetic advance, correlation coefficient, and path coefficient analysis for yield and its component traits. A considerable amount of genetic variability was observed among all the genotypes for all the characters under study. GCV & PCV were highest for seed yield per plant, followed by harvest index, biological yield and number of pods per plant.

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.

The pod yield was significantly and positively correlated with pod weight, pod girth, pericarp thickness, seed weight per pod, number of pods per plant and weight of 100 seeds. The path coefficient analysis using the phenotypic correlation coefficient among the pair of characters showed that number of pods per plant had the highest positive direct effect on yield. At last it could be concluded that PSM-3 and PSM5 are best performing varieties for this region according to green pod yield.
