Abstract:
Correlation and path coefficient investigations were conducted on a combined population comprising 29 Advanced Breeding Lines (ABLs) along with five control varieties resulting from the cross 16P2 X Kashi Hemanth in tomato (Solanum lycopersicum L.). The experimentation took place in the agricultural fields of Kanaykanahalli village, Belur taluq, Hassan district, spanning from 2020 to 2022. The outcomes revealed notable and favorable correlations between yield per plant and traits including number of fruits, fruit length, average fruit weight, fruit width, plant height, number of branches, and days to 50 per cent blooming, observed both at the phenotypic and genotypic levels. These findings imply that selecting genotypes based on these attributes could facilitate the identification of high-yielding and stable plants. Path analysis further demonstrated that the number of fruits per plant exhibited the strongest positive direct effect on yield per plant, followed by fruit length, number of branches, average fruit weight, firmness, days to fifty per cent flowering, and Total Soluble Solids (TSS).
