“…This study revealed that hybrids HRA 14 HRD 7, HRA 13 HRD 7, HRA 20 HRD 1 and HRA 20 HRD 6 could perform better than existing popular variety Srijana. However, result of study conducted by Chapagain et al (2014) showed that 53.5 gm of fruit weight of Srijana) in a trial conducted in Lumle, Kaski. In a study conducted in Regional Agriculture Research Station (RARS), Parawanipur of Nepal Agriculture Research Council (NARC), 1697 gm of fruit yield per plant was observed from Srijana hybrid (Shrestha and Shah, 2014).…”

“…According to Chaudhary and Khanna (1972) yield of open pollinated tomato is 20 to 25% less as compared to hybrids (Islam et al, 2012). Varietal development and continuous evaluation is needed for providing sufficient varietal options for the producers (Chapagain et al, 2014). Therefore research should be oriented to develop high yielding tomato varieties which also meet the demand consumer in reference with fruit quality.…”

An experiment was conducted to evaluate tomato hybrids (Lycopersicon esculentum) for qualitative attributes of tomato fruits in Horticulture Research Division, Nepal Agriculture Research Council, Khumaltar, Lalitpur, Nepal. Fruits from newly developed eleven hybrids from council and an existing popular tomato hybrid, "Srijana" were selected to evaluate and characterize yield and quality attributes. In this study vegetative character, fruit quality parameters and yield of tomato hybrids were observed and recorded. Fruit quality parameters of each hybrids were distinctly varied with each other. Indeterminate growth habit was observed from HRA 13 HRD 7, HRA 14 HRD 7, HRA 17 HRD 1, HRA 17 HRD 1, HRA 20 HRD 4, HRA 20 HRD 1 and Sirjana while HRA 15 HRD 6, HRA 16 HRD 1, HRA 16 HRD 4 and HRA 20 HRD 6 showed determinant type of growth habit. The total fruit yield per hectare ranged from 80.83 ton/ha (HRA 14 HRD 7) to 45.89 ton/ha (HRA 15 HRD 6). Yield of hybrids HRA 13 HRD 7, HRA 13 HRD 7, HRA 20 HRD 1, HRA 20 HRD 2, HRA 20 HRD 6and HRA 16 HRD 1 had 78.50 ton/ha, 73.75 ton/ha, 70.44 ton/ha, 68.72 ton/ha, 64.64 ton/ha respectively which were superior to an existing popular variety, Srijana (62.33 ton/ha). Hybrids having indeterminate growth can be recommended for plastic house cultivation and hybrids with determinate growth habit will be suitable for seasonal cultivation. Study on consumer preference and multiyear multi location trial of the good performer hybrids is to be done before recommendation and promotion of these hybrids in Nepal.

“…They found that yield variation from 54.39 to 80.83 mt ha -1 among 13 hybrids evaluated in the same field conditions at an altitude of 1350 m (mid-hills) of Nepal. Chapagain et al (2014) reported tomato yield ranging from 71.4 to 105.8 mt ha -1 among six genotypes at an altitude of 1640 m (mid-hills) under plastic house conditions. In our open field study, the highest yield was produced by HRA43 (39.63 mt ha -1 ) which was higher than the national average of the country (18.01 mt ha -1 ) and comparable with world productivity (35.90 mt ha -1 ).…”

“…Devkota et al (2018) evaluated hybrid cultivars at mid-hill conditions of Nepal (Khumaltar) and found that 'HRA14 x HRD7' produced the highest yield (80.8 mt ha -1 ). Chapagain et al (2014) evaluated some exotic hybrids and recorded 'Winsari' the highest yielding (105.8 mt ha -1 ) cultivar. However, these exotic varieties may not give stable performance over the season, seeds of these varieties are not available in the market and most of these varieties are not registered in Nepal.…”

The productivity of tomato in Nepal is very low due to lack of high yielding, disease and pests resistant varieties. An experiment was carried out to evaluate horticultural traits of 50 genotypes obtained from World Vegetable Centre (WorldVeg), Taiwan and SAARC region, and local collections during March to August 2020 in open field conditions at National Horticulture Research Centre, Khumaltar, Lalitpur. The objectives were to identify promising open-pollinated tomato cultivars for high yield, appropriate fruit size, and disease resistant. The experiment was carried out in a randomized complete block design with three replications. Results showed significant differences in yield and yield attributing characters including virus infection. The highest yield (39.6 mt ha-1) was produced by HRA43 and it was followed by HRA33 (26.4 mt ha-1). Among the WorldVeg OP lines, AVTO1429 produced the highest yield (16.21 mt ha-1) and it was followed by AVTO1717 (12.95 mt ha-1), AVTO0922 (11.83 mt ha-1) and AVTO1219 (11.7 mt ha-1) respectively. Most of the WorldVeg lines performed better than the check variety ‘Pusa Ruby’. Genotype HRA43, Red Local and Sindhupalchock Local were not affected by virus while Yellow Local showed 3.3% infection. Among the WorldVeg lines, AVTO1712 (20%), AVTO1717 (20%) and AVTO1718 (13%) and AVTO1219 (15%) showed less than 20% virus infection in the open field conditions. Cluster analysis using the unweighted paired group method with arithmetic mean showed that cluster-1 was the largest cluster comprised of 40 genotypes followed by cluster-2 and cluster-4. Genotypes from cluster-4 showed the higher fruit yield (25.1 mt ha-1) and resistant to the virus and the highest number of fruits per plot (1978 in 4.5 m2 area). The yield was low in cluster-1 which could be due to the heavy rainfall during the vegetative and reproductive stages. Genotypes Red Local and Sindhupalchock Local could be used in future tomato breeding program due to their resistant to TYLCV, higher potential yield and highest plant vigour in open field conditions at the mid-hill of Nepal. Considering the overall performance, genotype HRA43, HRA33 and AVTO1429 were promising lines with performance for yield and other horticultural traits.

This article presents a comprehensive comparative evaluation of tomato varieties. The study focused on key yield attributes, including plant height, fruits per cluster, fruit diameter, fruit length, yield per hectare, days to 50% flowering, and maturity. Significant variations in plant height were observed among the varieties. Monoprecos had the tallest plant height (125.73 cm), while 2-HRDTOM035 was the shortest (83.26 cm). The number of fruits per cluster varied, with HRD109 producing the most (7.33) and HRDTOM084 the least (3.86). HRDTOM084 excelled in fruit dimensions, having the largest fruit diameter (19.88 mm) and fruit length (5.94 cm), whereas HRD109 showed the smallest diameter (10.16 mm). Yield per hectare also differed significantly, with HRDTOM084 delivering the highest yield (11.06 t/ha), and 2-HRDTOM035 recording the lowest (4.84 t/ha). The study also analyzed days to 50% flowering, revealing HRDTOM084 as the slowest to flower (48.60 days) and Monoprecos as the quickest (30.60 days). Days to maturity mirrored these results, with HRDTOM084 taking the longest to mature (93.73 days). In comparison, earlier studies with nine open-pollinated and hybrid varieties in other regions, such as Khajura and Lumle, revealed similar patterns in yield and growth, confirming the genetic diversity in tomato production. Overall, HRDTOM084 emerged as the most promising variety for commercial cultivation due to its superior yield, fruit size, and productivity, while Monoprecos and 2-HRDTOM035 may be suitable for environments that require shorter growth cycles. This review highlights the importance of selecting tomato varieties based on specific traits, such as plant height, yield potential, fruit quality, and adaptability to local growing conditions, to optimize production. Future research could focus on enhancing disease resistance and studying performance under different climatic conditions to further improve tomato cultivation practices in Nepal.
