This study was carried out to gain basic informations about amylogram, antioxidant activity function and physicochemical properties for kernel of the newly developed waxy corn hybrids. The used materials were produced in 2008 and cultivated at breeding farm of CNU in 2009. From amylogram analysis, peak and minimum viscosity of the used hybrids were appeared in CNU08H-71 and CNU08H-69 hybrid, respectively. DPPH free radical scavenging effect marked as election donating ability was highly appeared in CNU08H-15 and CNU08H-69 hybrid, while CNU08H-h102 hybrid was the lowest. Hardness of kernel was highly appeared in CNU08H-35 hybrid, and chewiness and gumminess were also the highest in this hybrid, but those of CNU08H-h105 hybrid were the lowest. In these facts, we confirmed that the used hybrids were very different among traits related to amylogram, functions and table qualities. Accordingly, development of the new waxy corn hybrid will be profitable to select and develop as a crossing combination including many excellent traits.

This study was carried out to develop a new sweet sorghum for biomass by using mutagen, gamma-ray. Seeds treated were gained from National Genetic Resource Center, RDA, and these seeds were irradiated with gamma-ray (400Gy) at KAERI. CNUS-M113 and CNUS-M134 among 169 collected accessions were evaluated a promising line for biomass due to increasing of fresh and dry weight. In addition, this line was high in stem height, number of tiller and fresh weight per plant than check, Hwang-gum chal sorghum. Accodingly, this line demanded for leading variety the production test and cultivation adaptability in future years.

This study was carried out to find a botanical and antioxidant characteristics in CNU rice lines developed in the crop Genetics & Breeding Lab. At (CNU) the CNU lines including CNU-Hinhchal, were planted one plant per hill by hand by 30 ㎝×15 ㎝ density at CNU paddy rice farm on May 11, 2011. Clum length of Shinsunchalbyeo as check among used line was longest than others, while that of CNU-114 was shortest among lines. For the number of tillers per plant, CNU-Hinhchal was higher as 20 than other lines but CNU-112 and Shinsunchalbyeo were lowest as 12. The number of spikelets per plant was highest in CNU-Hinhchal as 1,800 but that of Milyang 225 was lowest among the used lines.

The major characteristics of the developed corn hybrids were compared at each different planting time; 1st time(April 28) and 2nd time(August 20), respectively. Among traits surveyed, stem height showed highly at 1st time than 2nd, while ear height, stem diameter and ear length were similar at two times. Sugar content of the used hybrids showed highly at 2nd planting time than 1st. Pericarp thickness was also high at 2nd planting time. Especially, among hybrids CNU99 was the highest in stem height and ear length, CNU11 and CNU56 were high in sugar content, and CNU51 and CNU124 were thiner than other hybrids in pericarp thickness. Accordingly, these hybrids will be planted and recognized in 2nd yield trial for superior corn hybrid selection.

This study was carried out to compare botanical characteristics, physicochemical properties related to table quality and feed values and develop a new variety among 12 developed waxy com hybrids. These materials were produced in 2008 and cultivated in 2009 at Com Breeding and Genetics Farm of Coll. of Agri. & Life Sci., Chungnam Nat'l Univ. Botanical characteristics of used waxy com hybrids showed large difference among hybrids; stem height, ear height and ear length. In physical properties, range of kernel sugar content among used hybrids appeared 16.1 to 13.0brix(%). CNU08H-15, CNU08H-35 and CNU08H-h39 among these were highly appeared as 15 above and pericarp thickness of Yeonongchal was very thick as 46.0~mum , while CNU08H-39 among hybrids showed the thinnest as 23.0~mum compared to other hybrids. Protein content as a indicator of table quality was the highest in Ilmichal among hybrids, while that of CNU08H-39 was the lowest, while amylopectin content was the highest as 94.5%, From experimental results, Daehakchal Gold 1, CNU08H-h121 and CNU08H-39 including check Yeonyoungchal were highly evaluated as new hybrid in thinner pericarp, high amylopectin and chewiness.
