225 rice sample of Mot Bui Lun variety were collected at Tran Van Thoi district, Thoi Binh district and Ca Mau city. Then, those were classified according to collected areas and evaluation based on distributable level of traits in fields. Screening the best individuals. 225 distinct lines of Mot Bui Lun variety selecting in the first crop and continuing to evaluate agronomic traits, yield and yield components in the second crop (G1) and the third crop (G2). Results of the morphological observation of Mot Bui Lun variety showed that most of those fluctuated significantly between individuals, excepting stems height and auricle color of leaves of some individuals with purple stripes instead slight purple. Due to be not uniform in shape, a lot of individuals with different morphological characteristics as description be removed. Coordinating phenotype and genotype (molecular marker) using microsatellite in order to analysis genotypes on the rice lines of Mot Bui Lun variety showed highly genetic diversity. Although the same variety, but PCR products produced many alleles on the same line. Through analysis of 4 polymorphism primers RM13, RM223, RM106, RM3252-S1-1 produced polymorphism and chose a inbred line. Mot Bui Lun (12), the lines had well shape, outstanding and together with good traits. Particularly, using SSD-PAGE protein method may appear the bands but discrimination of inbred lines is unclear. Mot Bui Lun variety after revigorating and transferred to Ca Mau province.
