Rice Variety Profile for M-208

Early maturing, semi-dwarf, glabrous, Calrose medium grain.

RES Rice Varieties

Variety: M-208

  • Former ID:
  • Year: 2007
Introduction

M-208 is an early maturing, semi-dwarf, glabrous, Calrose medium grain (CRMG) quality rice variety that has Pi-z gene resistance to race IG-1 of the rice blast pathogen found in California. It was developed by the CCRRF at the Rice Experiment Station (RES) and released to growers in 2006. M-208 parents involved M-204 and RES developed germplasm from M-401 crossed to Lafitte. Lafitte is a medium grain release from Louisiana State University and the source of the Pi-z blast resistance gene. 

Agronomic Characteristics

M-208 was compared very-early to early M- 206, M-207 (first CRMG with Pi-z blast resistance) and M-202 (Table 1). M-208 is essentially an M-202 agronomic type CRMG that is a significant improvement over M-207. Days to 50% heading for M- 208 averaged 1 day and 6 days later than M- 202 and M-206, respectively. M-208 is similar to M-202 in seedling vigor and lodging (even though it is 2 cm taller). Kernels of M-208 are slightly larger in size and weight compared to M-206, M-207 and M-202. Laboratory analysis for physicochemical characteristics by the USDA-ARS Rice Research Unit, Beaumont, Texas, indicates M-208 fits Calrose medium grain standards. Evaluations of milled rice samples by California rice marketing organizations and individual evaluators indicate M-208 is similar to M-206 M-207 and M-202 with small improvements noted in taste and texture for M-208. M-208 may be commingled with other Calrose medium grains.

Area of Adaptation

M-208 is adapted to the majority of M-202 growing areas north of the Yolo/Colusa County line and west of Highway 70. It has specific applications in those areas of Glenn and Colusa Counties that have recurring blast damage associated with reduced yields and milling quality. M-208 also provides another variety option for medium grain production in other areas.

  • Frank Maulana, Ph.D.

    Short Grain Breeder

    Dr. Frank Maulana is a rice breeder for the California Cooperative Rice Research Foundation (CCRRF). He is leading a short grain breeding program to develop improved short grain rice varieties for five market classes, including conventional or regular, low amylose, sweet or waxy, premium quality and arborio or bold grain. The objectives of the program include developing rice varieties with high and stable yield, high milling grain yield, seedling vigor, cold tolerance, lodging resistance, and disease resistance. He received a BS in Crop Science from Lilongwe University of Agriculture and Natural Resources (LUANAR) in Malawi. Then, he worked as a plant breeder at the Agricultural Research and Extension Trust (ARET) for five years. He then went on to obtain PhD and MS in Plant Breeding and Genetics from Kansas State University (KSU), Manhattan, KS. Before joining CCRRF, he was a postdoctoral researcher at Louisiana State University (LSU) AgCenter-Rice Breeding program. His research project at LSU focused on implementation of genomic selection in an applied rice breeding program.

  • Gretchen Zaunbrecher, Ph.D.

    Genetics Lab Director

    Dr. Zaunbrecher is the Genetics Lab Director for the California Cooperative Rice Research Foundation (CCRRF).  The Genetics Lab utilizes marker assisted analysis to provide valuable genetic information to assist the breeders in rice varietal improvement.  In addition, through traditional mutational breeding as well as gene editing, we hope to develop new varieties of rice with enhanced yield, herbicide, and disease resistance, and other agronomically valuable traits.

    Long Grain Breeder

    Dr. Nirmal Sharma is a plant breeder for the California Cooperative Rice Research Foundation (CCRRF), leading the long grain breeding project and incorporating disease resistance, high milling yield, seedling vigor, cold tolerance, and herbicide resistance into future rice varieties. He received his BS in Agriculture and MS in Biotechnology from Bangladesh Agricultural University. Then, he worked as a breeder in the Plant Breeding Division of the Bangladesh Rice Research Institute (BRRI) for several years. Next, he moved to the United States to pursue his PhD in crop sciences at the University of Illinois at Urbana-Champaign (UIUC). Upon completing his degree, he was a postdoctoral fellow at the Noble Research Institute before joining CCRRF.

  • Teresa B. De Leon, Ph.D.

    Medium Grain Breeder

    Dr. Teresa B. De Leon is currently leading the improvement and variety development of CCRRF medium grain project. She previously led the short grain breeding project from 2018-2021. Prior to her employment at the station, she worked as Plant Geneticist to University of California Davis for identification, origin, and prevention of weedy red rice. She developed pre-breeding and introgression lines of Louisiana rice with improved salinity tolerance for Louisiana State University Agricultural Center. As Assistant Scientist and Research Scholar, she has also worked at the International Rice Research Institute (IRRI) and University of the Philippines at Los Banos on disease resistance of rice and other crops. With several years of experience in rice research and development, Dr. De Leon is integrating the use of conventional and molecular tools in breeding for medium grains with high yield potential, high grain quality, wide adaptation, cold tolerance, disease and herbicide resistance, and most importantly, a rice with excellent cooking and taste quality for consumers.
