In order to analyze the molecular genetic characteristics of very early mature backbone parents in the northeastern alpine region, the field phenotype survey, identification of plant diseases and insect pests inoculation and SLAF-seq technology were combined to research genomic genetic characteristics of the very early mature backbone parents and their offspring derived varieties in the high cold region of Heilongjiang Province. The results showed that the genetic distance between Heihe54 and the derived varieties was close; the genetic distance between Heihe54 and Heihe18 was close, with a genetic distance of 0.416, however the genetic distance with Beifeng11 was far, with genetic distance of 0.57; while the genetic distance between Heihe18 and Heihe9 is the closest, with a genetic distance of 0.145. The backbone parents of Heihe54 and their derivatives have the same genomic segment, and the same allelic variation on chromosomes 4 and 9 exceeds 94%. It is believed that the characteristics of the precocious, pointed leaves, lodging resistance, short growth period, oil content, pod habits, germination ability at low temperature, strong adaptability and high yield of the backbone parents in the very early maturity group have become the genetic basis of the backbone parents in the progeny.
