Early, high yielding, resistant to blast disease, Calrose-type medium grain variety.

RES Rice Varieties

Variety: M-210

  • Former ID: 12Y3097
  • Year: 2018
Pedigree and Breeding

M-210 is a blast-resistant, high-yielding, early-maturing, Temperate Japonica, Calrose-type medium grain, formerly designated as 12Y3097, was a product of a DNA marker-assisted backcrossing. Its pedigree is M-206*8/97-Y-315vE where 97-Y-315vE is 18347/78Y043// 86Y013/3/Daegwanbyeo. M-206 is a high yielding, glabrous, early maturing, Calrose-type medium grain variety released by RES in 2003. It was chosen as a recurrent parent because of wide adaptability, good combining ability, and superior milling performance. Derived from a complex cross involving RES advanced rice lines, 97-Y-315vE is a very early (vE), blast resistant, short grain entry which was kept as a differential line to routinely test blast pathogen isolates in the RES greenhouse. In its pedigree, 97-Y-315vE listed Daegwanbyeo identified as a blast resistant parent. Daegwanbyeo is a cold tolerant, blast resistant short grain Korean variety developed by Crops Experiment Station, Rural Development Administration in 1986. It possessed the Pi-b gene which is linked to a SSR or microsatellite marker RM208 that was used in marker assisted selection (MAS).  M-210 is acceptable to the rice market as evaluated internally and externally for grain quality.

Agronomic Characteristics

The overall grain yield of M-210 across 43 SW Yield Tests averaged 9,300 lbs./acre compared to 9,370 and 8,910 lbs./acre for M-206 and M-208, respectively. The overall yield advantage of 12Y3097 over M-206 and M-208 were -0.74% and 4.4%, respectively. It yielded better (up to 10% yield advantage) than M-208 in most locations except Colusa (-6%), and competitive with M-206 though M-210 may not be as widely adaptive especially in colder rice areas.

 Compared to M-208, M-210 reached 50% heading in 83 days (3 days earlier), had slightly shorter plant height at 97cm, and about similar in terms of seedling vigor and lodging percentage. M-206 and 12Y3097 are agronomically similar in stature though in many cases, M-206 headed a day earlier.

Milling and Quality

The milled rice grains of M-210 on average were heavier (1000-grain weight =21.65 grams) and slightly wider (width=2.78 mm) compared to M-208 (21.19g, 2.75mm) and M-206 (20.73g, 2.73mm), while the grain length (5.96mm) and length/width ration (2.14) were in between M-206 and M-208. With slightly heavier grains and grain dimension meeting the criteria of the Calrose rice market, M-210 can be co-mingled with other Calrose rice varieties currently in production in California.

Milling data showed that the head rice yield of M-210 when harvested at 19-22% grain moisture is 65/70 (head/total) compared to 64/69 and 63/68 for M-206 and M-208, respectively. When cut at moistures above 22%, milling yield improved to 65/70. Below 19% harvest moistures, head rice dropped on all entries even further as grains became drier.

RVA and Quality Evaluation

The average apparent amylose content and protein content of M-210 is 15.7% and 6.6%, respectively, values that are very close to M-206 and M-208. All three had low gel type typical of a Calrose-type medium grain. Based on the results of the RVA, M-210 does not deviate from the profile of M-206 or that of M-208, meaning cooking characteristics were similar to M-206 and typical of a Calrose. Internal evaluation as well as and external cooking quality evaluation by selected marketing organizations showed similar observations. Feedbacks were favorable, indicating acceptability of quality in the market.

Blanking and Disease Screening Test

Tests in San Joaquin showed that M-210 had an average blanking of 1.8% compared to 1.7% and 3.5% for M-206 and M-208, respectively. Greenhouse blanking were 25%, 18% and 28% from M-210, M-206 and M-208, respectively. Results further showed that M-210 had better cold tolerance than M-208 and close to the tolerance level of M-206.

Reactions to stem rot, aggregate sheath spot, and blast diseases indicate that M-210 is blast resistant and had comparable averaged reaction to aggregate sheath spot. Reaction to stem rot of M-210 is slightly better than M-206 and M-208.
