Abstract

Rice is one of the most important food crops, particularly rice varieties used for processing, which have received increasing attention in recent years due to rising domestic demand and industrial utilization in Vietnam. Systematic evaluation of newly developed rice lines for yield, quality, and adaptability under South Central Coast conditions is necessary due to the decline in suitable processing varieties and the susceptibility of existing cultivars to major pests and diseases. Therefore, field experiment was carried out in spring season 2025 at Da Nang city (South Central Coastal Vietnam) to evaluate the growth, development, yield and quality of new promising rice lines and varieties for processing. Rice variety, namely ML202 (control) and 7 promising lines namely P598, P587, P685, P464, P620, P480, P509 were used for the study with three replications in a randomised complete block design. The results indicated that the highest leaf area index and flag leaf area obtained at the line of P620 (4.75 m2 leaves/m2 soil and 35.16 cm2, respectively)  The rice lines and varieties yield produced between 6.42 and 7.45 t/ha, in which yield of P464 and P620 lines were 7.33-7.45 t/ha greater than the control variety of 14.2-16.0%. Amylose content of all studied rice lines and variety were higher than 25%. Promising lines, namely P464 and P620 with the highest yield and good quality categorization for processing were proposed for futher study with other technical practices.
