Abstract:
In order to broaden the germplasm resource spectrum of multi-grain germplasm resources, distant hybridization can be carried out during the practical operation of multi-grain hybridization, so as to obtain more advantageous progeny, so as to screen out the high-quality and high-resistance multi-grain varieties suitable for Yanbian Area or the middle and early maturing area of Jilin Province, 118 different types of millet resource were used as materials from Korea and Japan were tested for adaptability in Yanbian Area. Biological characteristics, yield traits, stress resistance and disease resistance were tested and analyzed. The results showed that the introduced resource phenotypes were abundant. A total of 35 resources were identified suitable for Yanbian Area, including 10 resources with strong resistance and high yield that could be directly hybridized, 1 with characteristic resource and 5 silage type resources. These introduced millet resources can be used in hybrid breeding of millet after identification. It is of great significance for Yanbian prefecture and even Jilin Province to develop millet industry.
