Abstract:

The breeding status and genetic pedigree of aromatic rice varieties were analyzed, using 33 aromatic rice varieties approved by Heilongjiang province as materials. The results showed that the study on aromatic rice breeding in Heilongjiang province started late, and the regional distribution was obviously different. It was mainly concentrated in the first and second accumulated temperture zone, the third and fourth accumulated temperture zone were less. There were 27 aromatic rice varieties which derived from Wuyoudao 1 and Lianxiang 1, accounting for 81.8%. It indicated that the breeding resources of aromatic rice in Heilongjiang province is deficient, the genetic basis is very confined. The only way for the sustainable development of aromatic rice breeding in Heilongjiang province is to fully tap the varieties of farmers, actively introduce the field resources, create new backbone parents and enrich the genetic basis.
