Abstract

Bacterial blight (BB) disease reduces the yield of rice varieties and hybrids considerably in many tropical rice growing countries like India. The present study highlights the development of durable BB resistance into the background of an elite maintainer of rice, DRR17B, by incorporating two major dominant genes, Xa21 and Xa33 through marker-assisted backcross breeding (MABB). Through two sets of backcrosses, the two BB resistance genes were transferred separately to DRR17B. In this process, at each stage of backcrossing, foreground selection was carried out for the target resistance genes and for non-fertility restorer alleles concerning the major fertility restorer genes Rf3 and Rf4, using gene-specific PCR-based markers, while background selection was done using a set of 61 and 64 parental polymorphic SSR markers respectively. Backcross derived lines possessing either Xa21 or Xa33 along with maximum genome recovery of DRR17B were identified at BC3F1 generation and selfed to develop BC3F2s. Plants harboring Xa21 or Xa33 in homozygous condition were identified among BC3F2s and were intercrossed with each other to combine both the genes. The intercross F1 plants (ICF1) were selfed and the intercross F2(ICF2) plants possessing both Xa21 and Xa33 in homozygous condition were identified with the help of markers. They were then advanced further by selfing until ICF4 generation. Selected ICF4 lines were evaluated for their resistance against BB with eight virulent isolates and for key agro-morphological traits. Six promising two-gene pyramiding lines of DRR17B with high level of BB resistance and agro-morphological attributes similar or superior to DRR17B with complete maintenance ability have been identified. These lines with elevated level of durable resistance may be handy tool for BB resistance breeding.

Abstract

Additional file 1. Figure S1: Marker assisted backcross breeding strategy used in the present study. Figure S2: Analysis of donor parent genome introgression associated with Salinity tolerance QTL, Saltol locus using GGT version (2.0), a segment of 1.0 Mb was introgressed at the proximal end, 1.5Mb at the distal end from the donor parent genome in the best BC3F2 plant (i.e., RP6287-188-45-12-88), thus, in total, a segment of 2.5Mb was introgressed from the donor parent with respect to the genomic region in the vicinity of Saltol. The position of the polymorphic SSR markers in Mb on Chr. 1 is given in parenthesis adjacent to each marker. Figure S3: Screening for seedling stage salinity tolerance. (A) Uprooted seedlings of checks (ISM and FL478) and improved lines of ISM possessing Saltol QTL (IL1 to IL4), (B) Root morphology of checks ISM and FL478 along with introgressed lines IL-1(RP6287-88), IL-2 (RP6287-43), IL-3 (RP6287-12) and IL-4 (RP6287-178). Figure S4: (A): Improved bacterial blight and Salinity tolerance lines of ISM (B): Improved Salinity tolerance lines with better grain and panicle number; IL-1(RP6287-88), IL-2 (RP6287-43), IL-3 (RP6287-12) -Introgressed lines of ISM. Figure S5: Map depicting the salinity effected areas in the coastal regions of India (AICRIP centres). Map depicts the centres -Zone wise where the AICRIP trials were conducted and each zone was indicated in different colours. Figure S6: Frequency of the variants (SNPs, Insertions, and Deletions) per Mb that are present in the rice lines including Pokkali, FL478, ISM, and DRR Dhan 58 (IET28784). Figure S7: Neighbor-joining dendrograms showing the relatedness among the rice lines at the (A) Saltol locus (~0.9 Mb interval) and (B) the OsSKC1 gene based on the variants data. The data indicates no considerable difference in the relatedness among the rice lines ta the Saltol locus but a clear relatedness among the salt-tolerant lines at the OsSKC1 gene locus. The numbers on the branches indicate the distance between the rice lines (DRR Dhan58 is the line IET28784).
