Evaluating the rice genotypes at various growth stages under agro-climatic conditions of Dera Ismail Khan

Abstract

This research study was conducted for evaluation of 5 genotypes of rice (KANGNI-27, MATHRA, E-107, E-94, and IRRI-06) for different traits at various growth stages. The experiment was done at the Agriculture Research Institute, Dera Ismail Khan during the kharif season of 2020. The study was designed as RCBD with three replications. Data was recorded including length of seedlings, length of leaf, width of leaf, number of tillers, and height of plant at various growth stages, at nursery stage, after 10, 20, 30 and 40 days of plantation. At the nursery stage, genotype MATHRA showed the high seedling length (48.89 cm), genotype IRRI-06 had the longest leaves (18.44 cm), and genotype E-94 had the widest leaves (6.78 mm). After 10 days of plantation, the genotype KANGNI-27 had the highest number of tillers (4.33), genotype MATHRA had the longest leaves (21.67 cm), and genotype E-94 had the widest leaves (7.22 mm). Twenty days after transplantation, genotype KANGNI-27 had the highest number of tillers (10.78), genotype MATHRA had the longest leaves (32.67 cm), and genotype IRRI-06 had the widest leaves (8.11 mm). Likewise, 30 days after transplantation, the genotype E-94 had the highest number of tillers (16.22), genotype MATHRA had the longest leaves (36.78 cm), and genotype KANGNI-27 had the widest leaves (10.11 mm). Moreover, at 40 days after transplantation, genotype MATHRA showed the tallest height of plant (36.78 cm). These findings can be used in future breeding programs to develop new rice varieties that are better adapted to Dera Ismail Khan climatic conditions. © 2023 The Author(s)
