Abstract
An experiment involving twenty four genotypes of chilli and three created environments (E0 – No spray, E1 – Single spray on NAA @ 40 ppm and E2 – Double spray of NAA @ 40 ppm) was carried out during spring summer season of the year 2006 at Vegetable Research Centre, Pantnagar to determine the best genotypes, suitable environment and their interactions for higher production.
Out of the three environments, E2 was found better for red ripen fruit yield, number of fruits/plant, 100-seed weight, seed : husk ratio, minimum incidence of disease viz., anthracnose and leaf curl virus whereas, E1 performed better for fresh and dry weight of shoots/plant, fruit length, fruit periphery, weight of fruits/plant, number and weight of seeds/fruit.
Significant variations were observed for all the 18 characters. Among genotypes viz., G23 (PC-2062), G24 (PC-2064) and G22 (PC-2057) produced significantly more number of fruits/plant and G20 (PC-7) followed by G21 (PC-56) and G2 (Co-4) performed better for weight of fruits/plant. Genotypes G23 and G21 produced 110.26 and 71.60 per cent higher yield over check variety Pant C-1, respectively. Longest fruits (13.59 cm) were obtained in G20 (PC-7) whereas higher TSS value (16.77°B) were recorded in G2 (Co-4). More number and weight of seeds/fruit were recorded in G22 (PC-2057). Out of all the 72 interactions, G23 E1 was found better for number and weight of fruits/plant whereas, G23E1 (254.42 q/ha), G22E1 and G2E2 produced higher red ripen fruit yield over rest of the interactions. Each genotypes produced variable results under different environments and for different characters. However, the G23 (PC-2062) produced highest fruit yield under single spray of NAA @ 40 ppm followed by PC-2057 whereas, (Co-4) produced higher yield under double spray of NAA (E2).
