Abstract: Plant height imparted no positive indirect effect was visible to be highest via. Fresh fruit weight (-0.1011), length of internode (-0.0872), days to 50 % flowering (-0.0579), days to first flowering (-0.0389), fruit length (-0.0273), number of branches per plant (-0.0169), days to first picking (-0.0153), number of fruits per plant (-0.0139), first fruiting node (-0.047). Number of branches per plant was recorded to have highest positive indirect effect on fruit yield per plant via plant height (0.0090).However, negative indirect effect was recorded on days to first flowering (-0.0403), days to first picking (-0.0399), first fruiting node (-0.0356), fruit length (-0.0307), length of internode (-0.0191), days to 50 % flowering (-0.0154), fresh fruit weight (-0.0141), number of fruits per plant (-0.0116). Length of internode had significant positive indirect effect on fruit yield per plant via fresh fruit weight (0.3261), plant height (0.2870), days to 50 % flowering (0.2845), fruit length (0.1828) days to first picking (0.1073), days to first flowering (0.0873), first fruiting node (0.0387).However, negative indirect effect was recorded on number of branches per plant (-0.01181), number of fruits per plant (-0.06858). Days to 50 % flowering had significant positive indirect effect on fruit yield per plant via. Number of branches per plant (0.0104), number of fruits per plant (0.001).However, negative indirect effect was recorded on length of internode (-0.0313), days to first picking (-0.0215), plant height (-0.0210), fruit length (-0.0191), days to first picking (-0.0181), first fruiting node (-0.0142). First fruiting node expressed highest positive indirect effect on number of branches per plant (0.1388), fruit length (0.1242), days to 50 % flowering (0.0680), fresh fruit weight (0.0693), days to first flowering (0.0680), days to first picking (0.0097).However, negative indirect effect was recorded on number of fruits per plant (-0.0442). Days to first flowering was recorded to have highest positive indirect effect on fruit yield per plant via. Number of branches per plant (0.0538), fresh fruit weight (0.0090), fruit length (0.0086).However, negative indirect effect was recorded days to first picking (0.0498), days to 50 % flowering (-0.0359), plant height (-0.0276), length of internode (-0.0189), first fruiting node (-0.0233), number of fruits per plant (-0.0178). Days to first picking were significant positive indirect effect on fruit yield per plant via. days to first flowering (0.0162), number of fruits per plant (0.0148), first fruiting node (0.0047), days to 50% flowering (0.0138), length of internode (0.008), plant height (0.035), fresh fruit weight (0.008).However, negative indirect effect was recorded through number of branches (-0.0173) and fruit length (-0.0004). Fruit length manifested highest positive indirect effect on fruit yield per plant via fresh fruit weight (0.0473), first fruiting node (0.0269), length of internode (0.0249), days to 50 % flowering (0.0238), number of fruits per plant (0.0137), plant height (0.0122).While, negative indirect effect was recorded number of branches per plant (-0.0259), days to first flowering (-0.0055), days to first picking (-0.007). Number of fruits per plant had positive indirect effect on days to first picking (0.0078), first fruiting node (0.0067), days to first flowering (0.0043), fresh fruit weight (0.22) while negative indirect effect on number of branches per plant (-0.0068). Fresh fruit weight had significant positive indirect effect on fruit yield per plant via. fruit length (0.1453), plant height (0.1394), length of internode (0.1367), days to 50 % flowering (0.0095), days to first picking (0.0049) while, negative indirect effect on days to first flowering (-0.0175).
