Agro-morphological Characterization Assessment of Rice (Oryza Sativa L.) Varieties

Rice ( Oryza sativa L.) is an essential constituent of the global food chain. The goals of this study are to assess the field performance, character association and variability of 30 rice varieties ( Oryza sativa L.) accessions collected from various locations of Bangladesh. To evaluate the morphological variability, yield variability and correlation, the study employed a randomized complete block design (RCBD) with three replications. ACC04 exhibited the highest yield (186.19 g), total number of grains per panicle (197.33), panicle length (29.1 cm), the number of filled grain (188.6), grain length (9.86 mm), grain width (3.34 mm), defective grain length (7.63 mm), defective grain breadth (2.92 mm) and 1000 seed weight (31.26 g) and gave lowest the number of unfilled grain (8.6). It can be concluded that rice accessions exhibit a diverse array of qualitative and morphological traits. The varieties were divided into six groups based on cluster. In Cluster I and III, ACC4 gave the highest performance followed by ACC01 and ACC22 in grain length, grain breadth defective grain length, defective grain breadth and 1000 seed weight. Therefore, ACC04, ACC01 and ACC22 would be best and promising variety for rice production.
