The morphogenesis of panicle and spikelet in paddy rice has been studied in high yielding Indica$\times$Japonica hybrid cultivar, Milyang 23 and a Japonica type cultivar, Koshihikari. Germinated seeds planted in $5000^{-1}$ a pots filled with submerged soil and cultured under natural conditions. The young panicle of main stem were continuously dissected and observered by Cryo-SEM from the panicle initiation stage until heading stage. Although the date of panicle differentiation and heading in Koshihikari earlier than those of Milyang 23. the sequence of panicle development in two cultivars begins when first bract primordium at opposite side of flag-leaf primordium differentiated, synchronously followed by growth of the primary branch primordia (PBPs) and secondary branch primordia (SBPs), spikelet primordia(SPs), glumes as lateral organs on rachilla and organs composing single floret, and successive sporogenesis in the young spikelets continue after the enclosure by lemma and palea. The PBPs are acropetally initiated from the base of the panicle primordium, and the SBPs alternately differentiate from the base of upper PBP which differentiate later than the lower PBP. Spikelet development starts at the top of upper side PBP of the young panicle and continue basipetally even though SBPs continue to develop at the lower primary branch. Each PBP, SBP and SP differentiate with differentiation bract or bract hair cell around the base of each their primordia. The observation could confirm that Milyang 23 has not only 2~3 more defferentiated PBPs, but also more SBPs and SPs especially from middle-lower primary branch, at end of their differentiation stages, as compared to those of Koshihikari.

This study is made of proofreading some documents about ‘Tripitaka Koreana’, which was unknown and not noticed quite well until now and is also for montemplating the features of ‘Qidanzang’ that were accepted in ‘Tripitaka’. By all the researches the following facts were found out. First, ‘Qidanzang’ included in ‘Tripitaka’ were all 18 cases. Second, ‘Qidanzang’ that were corrected and accepted into ‘Tripitaka’ were 42cases. Third, ‘Qidanzang’ that have errors at comparing documents were all 11cases. Fourth the sutra that were accepted in the comparative book were all 57 cases. Fifth, unaccepted sutras , which were found out at comparative documents, were 4cases. At last, from the analysis abouve, we notice that most of the ‘Qidanzang’, not part of it, were accepted into ‘Tripitaka Koreana’ and like the previous viewpoint, ‘Qidanzang’ was an excellent book but it also had a few mistakes.
