The Hybrid Progeny Performance In Cross Breeding Of Cymbidium Hybridum

Cymbidium hyridus, native to India, Burma, Thailand, Vietnam and Chinese southern areas of epiphytic orchids of the genus some strong big flower seeds and mainly in these seed for the artificial hybrid parents get, is a general designation of Cymbidium bred through artificial hybridization,the flowers are gigantic, variety. In order to breed the line with good plant type and high ornamental value of the line, this paper adopts the traditional breeding methods, C. Waltz ’Romance’(C. Waltz ’Romance’), C. Lucky Gloria ’Aguri’ (C. Lucky Gloria ’Aguri’), C. skymint ’Pattyunde’ (C. skymint ’Pattyunde’), Cym. Lovely Bunn ’Othello’ (Cym. Lovely Bunn ’Othello’), C.Massachusetts Lika (C. Massachusetts Lika), C.Spring 4 (Cym. YangChun Four), and C. Confidante (C. Confidante) 7 species of Cymbidium hybridum varieties as parents, reasonable arrangement of hybrid combination, the main purpose is to plant breeding has excellent ornamental value and high strain and by comparing the hybridization combinations of different representative types after the difference in breeding rules analysis of cymbidium. The research results show that:(1) The C. Confidante as parents can make the hybrid offspring plant become upright; the C.Massachusetts Lika as parents can improve the plant height of hybrid progenies; in addition, C. Waltz ’Romance’ and C. Lucky Gloria ’Aguri’ can make the stem leaf number and leaf width of hybrid offspring increased gene; C.Massachusetts Lika as the number of hybrid offspring of the flowers when kiss increase.(2) By the two element method to analysis,all parents and their hybrid offsprings are erect scape system, by the C. Massachusetts Lika and C. Lucky Gloria’Aguri’the 177-1 hybridization are classified and display 177-1 belongs to erect scape, the red group, big flower type, sharp lip type,094, 179 and C. Waltz ’Romance’ are flowers round lip type green group; and 154, 168,176,182,189 and C.skymint’Pattyunde’, Cym. Lovely Bunn’Othello’ and spring Cym. YangChun Four are yellow group,168 andCym. Lovely Bunn’Othello’is the big flower round lip type, the rest is spent in the group round lip type; the rest are flower Round Lip pink group.(3) By entropy weighting method of grey correlation degree analysis method for the analysis of the correlation between parents, that correlation sequence: C. skymint ’Pattyunde’ >C. Waltz ’Romance’ >C. Confidante>177>169>179>176>17 1>094>C. AugustineWong>C. LuckyGloria ’Aguri’>154>161>168>189>191>182>185> C. Spring 4>C. Massachusetts Lika, so C. Skymint ’Pattyunde’、177、094、176 and C. Waltz’Romance’be popularized in Sichuan province. The use of AHP method to comprehensively evaluate the offspring, discovered by the C. Waltz ’Romance’ and C. skymint ’Pattyunde’ this hybrid combination of offspring, the comprehensive index was significantly better than that of other combination.
