Yield and Yield Contributing Performance of 75 Tomato Germplasm in Bangladesh

Abstract

The study was conducted with 75 tomato germplasm/lines at the farm of Olericulture Division, Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during the winter season of 2020-21 to evaluate the WorldVeg tomato germplasm. The days to first harvest were varied from 106 to 116 days while twelve lines were harvested within 106 - 108 days. The number of fruits per plant varied from 11.7 to 71.3, while the range of single fruit weight was 16.4 - 186.6 g. Fruit yield per hectare was 15.7 - 150.4 t/ha where the highest fruit yield per hectare was obtained from the lines AVTO 1702 (150.40 t/ha), followed by AVTO 1409 (126.54 t/ha), AVTO 1010 (120.60 t/ha), AVTO 1712 (111.33 t/ha), AVTO 1711 (107.23 t/ha). The range of fruit length was observed 2.07 to 6.8 cm, while the fruit diameter was 1.9 to 7.4 cm. The range of pericarp thickness was 0.14 to 0.8 cm, while the range of number of locule was 2.0 to 8.2. The range of TSS level was 2.0% - 8.2%, while the shelf life of the tomato lines was recorded 5.2 to 10.3 days. Considering earliness, quantitative and qualitative characters, eleven WorldVeg Center tomato lines AVTO 1010, AVTO 1315, AVTO 1409, AVTO 1711, AVTO 1712, AVTO 1713, AVTO 1717, AVTO 1907, AVTO 1911, AVTO 1915 and AVTO 1921 were found promising. So, these eleven lines can be selected for further confirmation.
