Rice is one of the major cereal crops and eating and cooking qualities are very important for improving commodification of rice and people's life.We used backcross inbred lines(BILs)of BC₁F₁₀ generation as materials which were constructed by two parents of indica photothermosensitive gene male sterile(PTGMS)line Guangzhan 63S and rice potential restorer line CG173R and they contained the same alleles of starch synthaseⅡa gene(SSⅡ3)and granule bound starch synthase gene(Wx^b),and their hybrid by backcrossing and selfing for several generations.Furthermore,the genotypes,the eating and cooking qualities(ECQs)and RVA profiles were measured among the lines of BILs so that genetic effects of the minor genes were analyzed.The results showed that:1)Five different starch synthesisrelated genes ADPglucose pyrophosphorylase large subunit ADPG(AGPlar),starch branching enzyme Ⅲ(SBE3),Pullulanase gene(PUL),Soluble Starch Synthase Ⅰgene(SSⅠ)and Soluble Starch Synthase Ⅲ1 gene(SS Ⅲ1)existed difference for two parents.2)SSⅢ1,SBE3 and PUL genes had single gene separation,and two genes separation of SSⅢ1 and SBE3 genes,SSⅢ1 and PUL genes in lines of BC₁F₁₀.3)Their different effect of genotypes,and interaction had significant influence at 0.05 level or at 0.01 level on apparent amylase content(AAC),the gel consistency(GC)and part indices of RVA profiles.4)Effects of SSⅢ1 had significant influence on AAC at 0.01 level.Interaction effect of SBE3 and SSⅢ1 had significant influence on AAC at 0.01 level and had significant influence on Peak time(PeT),Pasting temperature(PaT)and GC at 0.05 level.Interaction effect of PUL and SS Ⅲ1 genes had significant influence on PeT,PaT and consistence value(CSV)at 0.01 level and had significant influence on peak viscosity(PKV),hot paste viscosity(HPV),Breakdown value(BDV),Cool paste viscosity(CPV),Setback value(SBV),AAC and GC at 0.05 level.In the background of Wx^b and SSⅡ3 genes,the results demonstrated that effects of SSⅢ1 and the genes interaction between SBE3 and SSⅢ1 have significant influence on AAC at 0.01 level;Interaction effects between SBE3 and SSⅢ1 and between PUL and SSⅢ1 have significant influence on GC at 0.05 level;Interaction effect between PUL and SSⅢ1 has significant influence on PaT at 0.01 level.The studies have importance for improving the rice eating and cooking qualities and accelerating the research on rice quality breeding.
