NTS improved the rotation grain yield significantly while no-till without stubble retention had the worst grain yield compare to conventional tillage system.The average yield of spring wheat under NTS was 18.10%,26.21%,13.15%,2.34%and 2.38%higher than that under T,NT,TS,TP and NTP respectively.The average yield of field pea under NTS was 20.25%,30.33%,15.83%,8.82%and 10.39%higher than that under T,NT,TS, TP and NTP respectively.

这归功于NTS处理改善了土壤结构性和渗透性能，并提高了土壤水分和肥力状况，最终体现为作物产量显著提高。6年间NT处理平均纯收益为1692.44￥/ha，比T、TS、NTS、TP、NTP增加了37.52%、194.58%、9.02%、86.79%、13.99%；平均产投比为2.98，比T、TS、NTS、TP、NTP提高了0.61倍、1.28倍、0.52倍、1.10倍、0.52倍。

As shown by the result, the biomass and astaxanthin content of oceanic red yeast was reduced due to the presence of β-ionone which inhibited the synthesis of carotenoids. The lethality rate of oceanic red yeast would attained 92.3% if 370 mg/L of the β-ionone concentration was contained in the plate medium. The oceanic red yeast mutated by ethyl methane sulfonate was cultured on plate medium containing 370 mg/L of the β-ionone. 200 mutants were randomly screened, positive mutants with increased the biomass, astaxanthin volumetric yield and astaxanthin specific yield accounted for 18% of the total strain, the mutants with higher biomass, astaxanthin volumetric yield and astaxanthin specific yield higher occupied 22.5%, 45% and 46%, respectively.

Genetic dissection of QTLs for yield traits were further conducted for the genomic regions harboring Pi25. It was found that two or more linked QTLs for yield traits were located in this region, and they had effects on each of the 6 yield traits studied. It remains unclear that the genetic drag between Pi25 and yield QTLs was solely resulted from unfavorable linkages, or partially ascribed to pleiotropism of Pi25.

应用2期2重复的小区产量性状鉴定试验，进一步剖析产量性状QTL，发现Pi25两侧区间影响所有6个产量性状，且该区间存在2个以上控制产量性状的不同基因座，但尚无法判定研究群体存在的遗传累赘是全部源于抗病基因与产量性状QTL的不利连锁，还是部分源于Pi25的一因多效。
