TAILIEUCHUNG - Genetic variability, correlation and path analysis in F6 generation of ridge gourd (Luffa acutangula (Roxb) L.) for yield and quality

The study on genetic variability, correlation and path analysis in F6 generation of ridge gourd (Luffa acutangla (Roxb) L.) for yield and quality was conducted at College Orchard, Department of Horticulture, Agricultural College and Research Institute, Madurai during the year 2019-2020. The aim of the present study is to develop high yielding, medium size fruit and good quality fruits of ridge gourd. | 2020 9 7 1012-1019 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 7 2020 Journal homepage http Original Research Article https Genetic Variability Correlation and Path Analysis in F6 Generation of Ridge Gourd Luffa acutangula Roxb L. for Yield and Quality R.

The aim of the present study is to develop high yielding medium size fruit and Ridge gourd GCV good quality fruits of ridge gourd. The 11 selected ridge gourd accessions derived from two PCV Heritability crosses viz. Virudhunagar local x Periyakottai local L3 x T1 and Virudhunagar local x Correlation Path Alathur local L3 x T2 along with checks used for this study. The present study was laid out in analysis Randomized Block design RBD with three replications. The results revealed that moderate GCV PCV and high heritability along with high genetic advance as percentage of mean Article Info recorded for the character fruit length and . Whereas low GCV PCV and low heritability along with low genetic advance was recorded for the characters Accepted node to first female flowering and and rind thickness 11 June 2020 and . Regarding correlation studies fruit yield was significantly Available Online 10 July 2020 and positively correlated with fruit weight and sex ratio. In the present study path coefficient .
