Research Abstract

Studies of chromosome were conducted to progress breeding of pear through genome studies. The results are as follows ;(1) Preparation of good chromosome sample using enzymatic maceration and air drying method was established, (2) The chromosome configuration was elucidated by banding technique using fluorochrome of CMA and DAPI, (3) The gene sites of rDNA and retrotransposons on chromosomes were detected by FISH(fluorescent in situ hybridization).
