| The overall nutrient component of Micro-endosperm super high oil corn(MESOC) was analyzed in this study, which the control was general corn, supersweet corn, and high oil corn. Primary study was done on simple correlationsbetween every trait of nutrition, correlation trend of parents and offspring,heredity trend of heterosis, difference of positive cross and back cross, varianceof different type and plant lines. The purpose is to investigate the contents ofnutrients component and heredity of nutrients in MESOC and probability ofapplication. The research results are as follow.1) The content of 19 nutrient traits of MESOC were higher than that inthree controls in the 25 traits measured. Compare with general corn, the contentsof oil of seeds (19.85%) , content of oil of embryo free (8.98%), ratio ofembryo/kernel (41.94%), the content of total proteins (21.58%), the contentof total amino acids (18.88%) , the contents of essential amino acids (7.18%),Lysine (0.89%), The content ofβ-sitosterol (314.99 mg/100g), Vitamin E(13.20 mg/100g), Oleic acid (7.49%), linoleic acids (9.31%), linolenic acid(0.28%), the content of zinc (80.76 mg/kg) , the content of copper (11.14mg/kg) were times of 4.78, 14.97, 4.02, 1.90, 1.93, 1.95, 2.97, 2.76, 4.06, 5.8,4.35, 5.6, 2.03, 1.9, respectively.2) There were some superiority different among typeⅡ, typeⅢ, typeⅣofMicro-endosperm super oil corn (MESOC). The content of oil of seeds,content of oil of embryo free, the content of total proteins, the content of totalamino acids, the content of essential amino acids, the content of Lysine, thecontents ofβ-sitosterol, Vitamin E, fatty acids, linoleic acids, the content ofmagnesium, iron, Zinic, the content of copper were the highest in the typeⅣcompare to those of other two type. The weight of 100 seeds, the content of oil of embryo, phytic acid, vitamin E, hard fatty acid, Manganese were the highestin typeⅢ. The ratio of embryo/kernel, ratio of embryo/oil, the content ofstarch, linolenic acid, palmitic acid, Calcium are the highest in the typeⅡ.3) There were a large variance in the different plants of theMicro-endosperm super oil corn (MESOC). Such as the weight of 100 seeds wasdispersed from 7.58g to 12.52g, The content of oil of seed was dispersed from14.64% to 25.44%. the ratio of weight of embryo/kernel was dispersed from31.54% to 54.83%. The content of total protein was dispersed from 19.62% to23.84%. The content of total amino acid was dispersed from 11.94% to 22.24%.The content of essential amino acids was dispersed from 4.53% to 8.54%. Thecontent of Lysine was 0.69% to 1.08%. The content of phytic acid was dispersedfrom 225.34mg/100g to 573.15mg/100g. The content ofβ-sitosterol wasdispersed from 223.08mg/100g to404.12mg/100g. The content of Vitamin E wasdispersed from 6.25mg/100g to 18.00mg/100g. The content of fatty acids was4.69% to 11.44%. The content of linoleic acids was dispersed from 6.94% to10.98%. The content of linolenic acid was dispersed from 0.16% to 0.52%. Thecontent of magnesium was dispersed from 811.37 mg/kg to 844.09 mg/kg. Thecontent of Zinc was dispersed from 69.12 mg/kg to 95.09 mg/kg. The content ofiron was dispersed from 41.67 mg/kg to 560.88mg/kg. The content of copperwas dispersed from 6.41 mg/kg to 17.64 mg/kg. The content of manganese wasdispersed from 0.00 mg/kg～5.71 mg/kg.4) The analysis of simple correlations between the nutrient traits wereshowed that it was very significant positive correlations that were between thecontent of oil of embryo and oil of seeds, the content of oil of embryo free andoil of seeds, the ratio of weight of embryo/kernel and the content of oil of seeds,the ratio of embryo/oil and the content of oil of seeds, the content ofβ-sitosteroland the content of oil of seeds, the ratio of embryo/oil and the ratio of weight ofembryo/kernel, the content of lysine and the ratio of weight of embryo/kernel,the content of iron and the ratio of weight of embryo/kernel, the content oflysine and the ratio of embryo/oil, the content of iron and the ratio of embryo/oil,the content of zinc and the content of total proteins, the content of total essentialamino acids and the content of total amino acids, the content of lysine and thecontent of total amino acids, and the content of lysine and the content of totalessential amino acids, the content of zinc and the content of total amino acids,the content of linolenic acid and the content of starch, the content of palmitic acid and the content of starch, the content of calcium and the content ofmagnesium, the content of zinc and the content of magnesium, respectively.It was significant positive correlations that were the content of fatty acids andthe content of oil of seeds, the content of magnesium and the content of oilof seeds, the content of oil of embryo free and the content of oil of embryo, thecontent of fatty acid and the content of oil of embryo, the content ofβ-sitosteroland the content of oil of embryo free, the content of magnesium and thecontent of embryo free, the content of fatty acids and the ratio of embryo/oil,then content of total amino acids and the content of total proteins, the content oftotal essential amino acids and the content of total proteins, the content of lysineand the content of total proteins, the content of iron and the content of lysine, thecontent of vitamin E and the content of phytic acid, the content of iron and thecontent of vitamin E, the content of linolenic acid and the content of linoleicacid, the content of linolenic acid and the content of palmitic acid, respectively.It was very significant negative correlations that were the content of starchand the content of oil of seeds, the content of linolenic acids and ratio ofembryo/oil, the content of linoleic acid and the content of fatty acid, the contentof linolenic acid and the content of fatty acid, the content of iron and the contentof linolenic acid, the content of magnesium and the content of palmtic acid,respectively. It showed significant negative correlations that were the content ofpalmitic acids and the content of oil of seeds, the content of manganese and thecontent of oil of seeds, the content of starch and the content of oil of embryo, thecontent of palmitic acid and the content of oil of embryo free, the content ofmanganese and the content of the content of oil of embryo free, the content ofstarch and the ratio of weight of embryo/kernel, the content of starch and thecontent ofβ-sitosterol, the content of magnesium and the content of starch, thecontent of palmitic acid and the content of phytic acid, and the content of copperand the content of fatty oil, respectively.5) The expression of heterosis trend between offspring and parents showedthe positive in the weight of 100 seeds in mid-parents heterosis and high-parentsheterosis. The mid-parents heterosis showed the positive in the content of Lysine.The mid-parent heterosis and high-parents heterosis showed negative in the ratioof weight embryo/kernel. The high-parents heterosis in the content of starch andphytic acid was negative. The other traits showed the different heterosis trend.6) The analysis of correlations between offspring and parents indicated that the content of Lysine and Vitamin E showed very significant positivecorrelations between F1 and female parent. It showed significant positivecorrelations between F1 and female parent that were the content of oil of seed,ratio of oil of embryo, ratio of oil of embryo free, ratio of weight ofembryo/kernel, the content of total amino acids, the content of starch, iron,manganese, respectively. It showed very significant positive correlationsbetween F1 and male parent that were the content of phytic acid and palmiticacid. It showed very significant positive correlations between F1 and averagevalue of parents that were the content of oil of seeds, embryo, embryo free, ratioof weight of embryo/kernel, the content of total proteins,Vitamin E, palmiticacid, magnesium respectively. It showed significant positive correlations thatwere ratio of embryo/oil, the content of fatty acid, linolenic acid.7) The experiment of positive cross and back cross showed that there werebig different in the content of linolenic acid and the content of iron. But othertraits didn't show any different.8) The variance of the different lines of the same type and different plantsof the same lines is very small and showed the traits were relative stable. Formany traits except of the content of calcium showed that the variance ofdifferent plants in the same line was smaller than that of different lines of thesame type. Those showed that there was some segregation of biochemical traitsin the process of selecting lines. |
