There is vast genetic diversity of Myanmar Mangoes. This study mainly focused on indigenous thirteen different mango landraces cultivated in central area of Myanmar, Kyauk-se District and their fruit characteristics by 18 descriptors together with genetic relationship among them by 12 SSR markers. Based on the morpho-physical characters, a wide variation among accessions was found. Genetic characterization of thirteen mango genotypes resulted in the detection of 302 scorable polymorphic bands with an average of 4.33 alleles per locus and an average polymorphism information content (PIC) of 0.7. All the genotypes were grouped into two major clusters by UPGMA cluster analysis and a genetic similarity was observed in a range of 61 ~ 85%. This study may somehow contribute insights into the identification of regional mango diversity in Myanmar and would be useful for future mango breeding program.

Mungbean(Vigna radiata (L.) R. Wilczek) is one of legume cultivated in south and east Asia. It well cultivated in high temperature and drought condition. In order to establish pure line for genomic studies, the agronomical characteristics of Korean mungbean landraces were evaluated. A total of 324 acessions derived from National Agrobiodiversity Center were selfed two times in 2021 nersery. Tree times of selfed from 324 accessions were characterized. The color of seed coat was divided into three groups: green, yellow and brown. Among them green color was the most common with 91.7%. Flower colors were divided into four groups: yellow, purplish yellow, greenish yellow and purplish green. Among them purplish yellow color had the highest with 77.8%. Out of 324 resources, only 4 showed compound leaves, and all resources had a heart-shaped leaf. The days to first flowering was 31 to 78 days. About 63% of the accessions bloomed 35 to 50 days after sowing. 324 Korean landraces are expected to be used as a population of the Korean mungbean core collection and serve as a basis for genomic breeding materials for mungbean.

This study was conducted to characterize the amylose and protein contents of 4,948 rice landrace germplasm using the NIRS model developed in the previous study. The amylose contents estimated by NIRS in the standard rice were Sinseonchal (6.881%) 4.994%, Chucheong (19.731%) 18.633%, Goami (23.246%) 20.548%. Protein contents were Sinseonchal (6.890%) 6.824%, Chucheong (6.350%) 6.869%, Goami (6.777%) 7.839%. The NIRS analysis showed that 1.1-2.7%point lower in amylose and 0.4-0.6%point higher in protein than standard contents. The average amylose content of the germplasm was 20.39% with a range of 3.97-37.13%. The average protein content was 8.17% with a range of 5.20-17.45%. Amylose contents with a range of 20.06-27.02% represented 62.20% of the germplasm. Protein contents with a range of 6.78-9.75% represented 81.60% of the germplasm. Korean landrace comprised 24.9% among the 4,948 germplasm collected from 41 countries. A specific range of amylose contents showed in Korea 16.58-20.06%, in Japan 20.06-23.25%, in North Korea 23.25-27.02% and in China 27.02-37.13%. Protein contents exhibited 5.20-17.45% evenly in the whole landraces, whereas Chinese landrace particularly observed with 6.78-8.27% and 9.75-17.45%. Fifty resources were selected with low and high amylose ranging from 3.97-6.66% to 30.41-37.13% respectively. Similarly fifty resources were selected with low and high protein ranging from 5.20-6.09% to 13.21-17.45% respectively. Landraces with higher protein should be adapted to practical utilization of food sources.

This study was conducted to compare the agronomic traits of well-known colored native soybean germplasms. Recently, we are increasingly interested in colored as various functional ingredient of soybeans have revealed. We used a total of 396 soybean genetic resources, consisting of ten "Seonbijabikong", 110 "Jyinunikong", 276 "Seoritaekong". We sowed on 10th June 2018 at the field of Nongsaensmyeongro in Jeonju city. The average number of days to flowering, days to maturing and days to growth of colored soybean were 53, 84 and 136 days, respectively. Days to flowering of "Seonbijabikong" were ranged from 41 to 50 days with an average 48 days, those of "Jyinunikong" were ranged from 39 to 72 days with an average 52 days. Days to flowering of "Seoritaekong" were ranged from 35 to 63 days with an average 54 days, which were earlier in "Seonbijabikong", and similar with "Seoritaekong" and "Jyinunikong". Days to growth of "Seonbijabikong" were ranged from 125 to 137 days with an average 132 days, those of "Jyinunikong" were ranged from 91 to 144 days with an average 130 days and those of "Seoritaekong" were ranged from 99 to 150 days with an average 139 days. they were shortest in "Jyinunikong" and longest in "Seoritaekong". The distribution of maturity period was from 6th September to 5th November. The maturity period was as early as September and yields were more than 100g per plant, which were all three accessions(IT161905, IT162602, IT269617), "Seoritaekong". They would be useful as breeding materials of colored soybean with early maturity. The 100-seed weight is important characteristics that distinguish the usage of soybeans. "Seoritaekong" and "Seonbijabikong" have large seed characteristics for cooking with rice, "Jyinunikong" has small seed it for medicine. The average 100 seed weight was 35.0g of "Seonbijabikong", 30.8g of "Seoritaekong" and 13.4g of "Jyinunikong", respectively. As for seed coat lust, the ratio of dull was as high as 100% of "Seonbijabikong" and 91% of "Seoritaekong", that of shiny was as high as 77% of "Jyinunikong". Cotyledon color of "Seonbijabikong" were all yellow, that of "Seoritaekong" were 94% of green. The other name of "Seoritaekong" is "Sokcheong", which means that cotyledon color is green. Therefore if cotyledon color of Seoritaekong is not green, it might be misidentified. In the future, we will increase the utilization through evaluation of functional component such as isoflavones and anthocyanins of colored soybean landraces.

Buckwheat (Fagopyrum esculentum Moench), one of the minor crops grown in Korea belonging to the Polygonaceae family, is an annual crop widely cultivated in Asia, Europe, and America and has a character of outcrossing and self-incompatibility. The objective of this study was to analyze the genetic variability, phylogenetic relationships and population structure of buckwheat landraces of Korea using SSR markers. Ten microsatellite markers have been detected from a total of 79 alleles among the 179 buckwheat accessions were collected from Korea. The number of allele per marker locus ($N_A$) ranged from 2 (GB-FE-001, GB-FE-043 and GB-FE-055) to 31 (GB-FE-035) with an average of 7.9 alleles. GB-FE-035 was the most polymorphic with the highest PIC value 0.93. Major allele frequencies ($M_{AF}$) for the 10 polymorphic loci varied from 0.12 to 0.97 with a mean allele frequency of 0.57. The expected heterozygosity ($H_E$) values ranged from 0.05 to 0.94 with an average of 0.53. The observed heterozygosity ($H_O$) ranged from 0.06 to 0.92 with an average of 0.42. The overall polymorphic information contents (PIC) values ranged from 0.05 to 0.93 with an average of 0.48. The landrace accessions of buckwheat used in the present study were not distinctly grouped according to geographic distribution. The study concludes that the results revealed genetic differentiation was low according to the geographic region because of outcrossing and self-incompatibility. We reported that our analyses on the genetic diversity of common buckwheat cultivars of Korea were performed by using of microsatellite markers.
