Abstract
Directorate of Agricultural Research (DoAR), Parwanipur, Bara is only one research station mandated to carry out research in vegetablesfor the Province 2 of Nepal. A series of on-station experiments under initial varietal trial (IET), coordinated varietal trial (CVT) and advance varietal trial (AVT), and on-farm experiments (farmers field trials, FFT) were conducted to select elite tomato, brinjal, broad leaf mustard, radish, hot pepper, ginger and turmeric genotypes for the central Terai conditions. The results from the IET revealed that open pollinated (OP) tomato genotype’ AVTO 1422’ produced the highest yield (38.58 t/ha) followed by ‘AVTO 1350’ (36.6 t/ha). Results from the CVT showed that OP tomato genotype ‘HRDTOM084’ produced the highest yield (28.5 t/ha) followed by ‘HRDTOM085’ (19.9t/ha). Results from the FFT in OP tomato also revealed that ‘HRDTOM084’ produced the highest yield (25.6t/ha) followed by ‘HRDTOM085’ (21.1t/ha). Results from FFT on hybrid tomato recorded that ‘HRA13 x HRD7’ produced the highest yield (37.4t/ha) followed by ‘HRA14 x HRD7’ (33.8 t/ha). Similarly, AVT on brinjal showed that ‘Parwanipur Selection-1’ was the highest yielding genotype (25.8 t/ha). FFT on broad leaf mustard recorded the highest leaf yield (19.8 t/ha) in ‘HRDBLM004’ followed by ‘Marpha Chauda Pat’ (15.2 t/ha). CVT on radish recorded the highest root yield (28.6 t/ ha) in ‘HRDRAD004’ followed by ‘HRDRAD003’ (28.0 t/ha). FFT on hot pepper recorded that ‘HRDCHI012’ genotype produced the highest yield (17.0 t/ha) followed by ‘HRDCHI009’(12.5 t/ha). From these results, the promising variety of brinjal’ Parwanipur Selection-1’ and tomato ‘HRA14 x HRD7’ hybrid genotype have been recommended for notification in the national seed system.
