Abstract:
The present investigation was carried out to estimate the magnitude of heterosis of selected parents and resultant F₁ hybrids for yield and yield components for commercial exploitation. Six ridge gourd lines viz., IC-308561, IC-523876, IC-523886, IC-523882, IC-539714 and Satputia were crossed in diallel fashion excluding reciprocals during rabi, 2021 resulting in the development of 15 one-way F₁ hybrids. A set of twenty two entries involving fifteen F₁ hybrids along with their six parental lines and one commercial check (Arka Vikram) were evaluated by raising each entry at a spacing of 2.00 m × 0.75 m in a randomized block design with two replications at Horticulture Research Station, Venkataramannagudem during summer, 2022 for eighteen biometric characters. For average fruit weight the cross combination IC-523876 X IC-523886 showed significant standard heterosis over commercial check Arka Vikram. Significant standard heterosis over commercial check Arka Vikram with regard to fruit yield per plant and its components was exhibited by the cross combination viz., IC-523886 X IC-539714 in positive direction.
