EVALUATION OF THE AGRONOMICAL TRAITS OF THE ROMISING RICE LINES TOWARDS THE NATIONAL RICE PRODUCTION

Abstract

Rice (Oryza sativa) is considered as one of the major national production in the agricultural section. One of the main tasks is highly recommended as breeding new high-yielding and high-quality rice varieties for contributing to the recent variety distribution. In this study, eight promising rice varieties, constructed by the conventional breeding, were evaluated in the fields in the Spring and Summer season in 2018. As the results, the promising rice lines were recorded as harboring good agronomical traits, such as short growth duration (123÷135 days in the Spring season and 90÷105 days in the Summer season), long grain (7,2÷7,6 mm) and low amylose content (15,2÷19,6%). Our analysis revealed that the promising rice lines had significantly higher values of yield components and yields as compared with HT1 and BT7 controls. The yields of the promising rice lines varied from 7,07 to 7,66 tons/ha (Spring season) and from 6,02 to 6,40 tons/ha (Summer season). Additionally, the promising rice lines also showed good resistance to major pests and diseases.
