Abstract

Abstract:

In this study, the indica-japonica attribute of eight reverted diploid lines were identified by InDel molecular marker. The hybrid combinations were made between the reverted diploid lines and photoperiod- and thermo-sensitive genic male sterile lines Peiai 64S (indica) and Nongken 58S (japonica), respectively. The genetic distance and cluster analysis of the parents and hybrids were carried out, the yield related traits of the hybrids and the male parents were investigated, then the over male parent heterosis and the competitive heterosis of the hybrids were analyzed. In addition, the correlation between parental genetic distance and the heterosis was analyzed to explore the feasibility of using parental genetic distance to predict heterosis. The results showed as follows: (1) The indica gene frequency of the reverted diploid lines ranged from 0.605 to 0.947. All lines had both indica and japonica genetic components, but the proportions of indica and japonica components were different from each other. (2) The genetic distance between the reverted diploid lines and Pei’ai 64S were 0.21-0.42, and that between the reverted diploid lines and Nongken 58S were 0.68-0.95. The materials with the same or similar indica-japonica attribute were clustered together, which clearly showed the genetic relationship between the materials. (3) The heterosis utilization of the reverted diploid lines needed the participation of wide compatibility genes. The hybrid combinations made between Peiai 64S that had wide compatibility gene and the reverted diploid lines had obvious over male parent heterosis and competitive heterosis in the effective panicle number per plant, the total grain number per panicle, and the filled grain number per panicle. In the yield per plant, eight hybrid combinations all showed over male parent heterosis and competitive heterosis, especially the yield per plant of HYP2 was prominent, up to 45.92%. (4) The genetic distance of parents was significantly positively correlated with the total grain number per panicle and the yield per plant of the hybrids, indicating that the InDel genetic distance can be used for predicting heterosis. The study confirmed that the reverted diploid lines from the tetraploid indica-japonica subspecies rice had both indica and japonica genetic components, and contained abundant genetic diversity. Using the reverted diploid lines, the hybrid combinations with super heterosis could be made, which providing a theoretical basis and reference for the utilization of indica-japonica subspecies heterosis through the combination of indica-japonica intermediate lines and photoperiod- and thermo-sensitive genic male sterile lines with wide compatibility genes. At the same time, we preliminarily confirmed the feasibility of the pathway “breeding new diploid rice varieties by using polyploid as the vector for creating variation”, which provided a new idea and approach for rice breeding.
