  • Super Hybrid Rice

    <正> Plant breeders realize that, up to now, there are only two effective ways to in-crease the yield potential of crops through breeding, i.e. morphologic improvementand heterosis utilization. However, the potential is very limited by using morphologicimprovement alone, and heterosis breeding will produce undesirable results if it doesnot combine with morphologic improvement. Any other hreeding approaches andmethods including high technology like molecular breeding must he incorporated in-to good morphologic characters and strong heterosis, otherwise there will be no actu-al contributions to yield increase. On the other hand, the further development ofplant breeding for high target must rely on the progress of biotechnology.

  • Study on the Absorption Spectra and Stability of Theaflavin Pigment

    <正> Theqflavin(TF) was extracted and purified from black broken tea. The purified TF possessed an absorption peak at the 363nm wavelength, and the solutions of TF remained stable under the conditions of pH3-6, below 80℃ within 60 minutes, as well as in 1%-4% Vc and 0.05-0.5mmol /L Na_(2)SO_(3) solutions. Fading occurred in 0.05mol/L Hf)^ solution.

  • RAPD Technique Used to Determine the Purity of Hybrid Hot Pepper Seeds

    <正> Two hybrid hot pepper varieties Xiangyan 5 and Xiangyan 10, and their parents were analyzed the polymerase chain reaction with MJ /PT 200 Peltrier Themal Cycler and DS 800 White-ultravilot Transilluminator to set up a RAPD system adaptable to the purity determination of the hy-brid seeds. Among the 39 random primers, 2 and 4 primers were found to be used effectively in Xiangyan 5 and Xiangyan 10 respectively.
