 ABSTRACT

The present investigation on heterosis was undertaken at College of horticulture, Bangalore during 2016-17. Twenty five hybrids developed by crossing five lines with five testers in L × T fashion were evaluated along with the parents in randomized complete block design with two replications. The magnitude of heterosis over the commercial check for node of female flower appearance (-28.95 to 28.07), days to female flower anthesis (-9.67 to -28.46), days to first fruit harvest (-3.14 to -23.74), number of fruits per plant (-17.68 to 44.44), fruit yield per plant (-55.16 to 55.79). Significant heterosis was recorded over better parent (BP) and commercial check (SH). In order of merit F1 hybrids Green long × Poinsette (55.79 %), Green long × Pusa Uday (54.30 %), Pondicherry 1 × Punjab Naveen (50.47 %) were recorded to be three best performing F1 hybrids for fruit yield per plant. The higher yield recorded by these hybrids could be due to increased number of fruits per plant. The best performing F1 hybrid Green long × Poinsette which recorded 55.79 per cent higher yield over commercial check may be exploited for commercial cultivation.
