1. Establishing a new Technology System for Genome Design Breeding of Rice
Normally, crop breeder selects a better individual from the segregating population for improving cultivars suited to needs of farmers and consumers via their experiences and the phenotypes. But now, a new Technology System for Genome Design Breeding of Rice provides molecular breeders a tool that be easier replacing any gene in the variety genome to change the genotype and phenotypes. Its essential components include Materials Storage, High-throughput Genotyping Platform, Individuals Databases, Digital Farm, Phenotypes Quantification System, Patents for precise breeding, etc. Dr. Lin has first established this Technology System for two elite rice varieties Koshihikari, the most widely grown variety and great grain quality in Japan, and Kongyu131, the most widely grown variety in China’s Heilongjiang province. This breeding model would be used in other crops in near future.
2. Improvements and Up-grade of Rice Varieties
The core goal of this new Technology System is to achieve the improvements and Up-grade of Rice varieties.  The system’s principle is inspired by PC software upgrades which are requested and updated constantly when software engineers or users find some bugs. Similarly, Molecular breeder could up-grade the variety when they find the shortcomings of it by analysing and replacing for a better gene genotype. Dr. Lin first used this principle in rice molecular breeding called Variety Up-Grade. Taking rice varieties Koshihikari and Kongyu131 as examples, they still have several undesirable traits, like low-resistance capability to rice blast or lodging, although they are main elite rice varieties in the local area for decades. Variety Up-Grade is a process constantly striving for perfection of a variety, keeping a variety’s existing fine properties and replacing undesirable characters.
3. Research on Rice Blast Resistance
Rice blast resistance breeding has always been one of the difficulties in breeding, for its big economical loss, poor harvest, various physiological races, spatial variation of population structure, etc. Dr. Lin’s research group, on the one hand, has scanned out the lacked and contained blast resistant genes in Kongyu131 variety’s genome, that providing direction on resistance breeding according to the gene-for-gene relationship between host and parasite. So far, this group has bred several improved Kongyu131 lines introgressed Pb1, pi21, Pi-d2 and Pi-d3 genes respectively. On the other hand, they devote to building an improved and accurate identification method for various physiologic races, as the existing methods, IRRI’s NILs (Near-isogenic Lines) and DNA fingerprinting of races, are limited-use and far from enough for breeding.
4. Research on Rice Variety Adaptation
Rice variety adaptation means almost every variety can only be grown in specific ecological environment. Dr. Lin is challenging to alter rice adapted area by changing some photoperiod-sensitive and temperature-sensitive genes of the variety. Japonica rice variety Koshihikari’s cultivation was limited in Kandon and Tohoku, japan. Dr. Lin has succeed changing the adaptation of Koshihikari, and has bred several new Koshihikari varieties suited to the area of south Vietnam and north Japan. Moreover, Kongyu131 is improved to be two new varieties “Jin Huang Dao 2 Hao” and “Jin Huang Dao 3 Hao”, adapting to the second and first accumulated temperature zones in Heilongjiang province respectively.
5. Research on Rice Eating Quality
Rice eating quality is a factor influencing people’s diet quality and food culture and is a more concerned issue in rice breeding. Koshihikari is a rice variety so fragrant, stick, smooth, elastic, chewy and sweet that it’s also known as the optimal choice for making sushi and as the model for designing rice cooker. It’s market recognition is still becoming higher since the half of last century. Likewise, Kongyu131 represents the good appearance of Chinese Northeast rice, in part due to its transparency and stickness. Dr. Lin’s research group has improved Kongyu131’s eating quality by replacing a few genes of its genome related to aroma, glutinosity and grain shape.
6. Research on Rice Yields
As a main standard for evaluating new rice varieties, rice yield is a never-ending breeding research topic. Factors that direct affect rice yields include spike number, ear length, kernels number per spike, kernel length, thousand kernel weight, etc. Other factors like plant height indirect affect rice yield as well. By replacing the dwarf gene sd1, Dr. Lin has improved the lodging resistance of Koshihikari and bred a series of new varieties, Koshihikari H4, KZ1and KZ4. Moreover, he has bred a new improved Kongyu131 variety, “Jin Huang Dao 1 Hao”, for directly-seeding in Heilongjiang province. In addition, this group studies the enhancement of rice yields through some related genes, gn1a and GS3.
