Abstract

• One of the activities for more food production in Myanmar was approached to perennial rice cultivation. The perennial rice (PR) cultivation for Myanmar section was conducted at Yezin, Nay Pyi Taw in 2020 to 2021. The seeds of four perennial rice cultivars (PR 23, PR 25, PR 101 and PR 107) were obtained from the Research Centre of Perennial Rice Engineering and Technology in Yunnan, School of Agriculture, Yunnan University, the People’s Republic of China. The experimental design was carried out using Randomized Complete Block Design (RCBD). The plants of PR cultivars from the sample plots were measured for plant height, numbers of tillers, numbers of panicles, panicle lengths, numbers of spikelets, filled grains weight, unfilled grains weight, filled grain percentages, 1000 grains weight and grain yields (baskets per acre). The tallest plant height (136.0 cm) was found in PR 101. The numbers of tillers in PR 23 and PR 25 were higher than PR 101 and PR 107. The highest filled grain percentage (98.4%) was observed in PR 23, however, the highest 1000 grain weight (31.9 g) was obtained in PR 107. The highest grain yield (105 baskets per acre) was observed in PR 107. The physicochemical properties of the cultivated soil were also recorded. In conclusion the cultivation of perennial rice cultivars can provide the sustainable production capacities for food safety in Myanmar.
