Variation Analysis Of Winter Brassica Juncea And Brassica Napus, Brassica Rapa Hybrids

Winter Brassia rapa is the most cold-resistant species in the three types of oilseed rape. Winter Brassia rapa has important economic significance and ecological significance In agricultural production in the North. Excellent agronomic traits and quality traits in winter Brassica Rape,winter Brassica juncea drought-resistant infertile and other fine features, On the theory and production of great significance about The Brassica juncea drought-resistant infertile excellent properties transferred to winter Brassia rapa and Brassica winter.1. Morphology, agronomic traits, winter survival rate, stomatal guard cells are in a perimeter between two parents of Brassica juncea and Winter Brassica rapa and winter cabbage Winter Rapeseed Hybrids. Hybrids POD isozyme detection parents of the bands and More of a band(Rf=0.143).2.Hybrid offspring blade protective activity, soluble protein, free proline and MDA content ranging between two parents.3.Podrate,affinity index, pollen viability,pollen-stigma interaction comprehensive analysis are in a perimeter between two parents.of the measurement results show of winter Brassica juncea × winter Brassica napus, winter Brassica juncea ×winter Brassica napus, winter Brassica juncea ×winter Brassica napus and winter rape, winter Brassica juncea×winter Brassica napus hybrids, Hybridization affinity differences, winter Brassica juncea ×winter Brassica napus > winter Brassica juncea× winter Brassica napus>winter Brassica rapa×winter Brassica juncea >winter Brassica napus× winter Brassica juncea.When winter Brassica rape hybridization, winter Brassica juncea when the highest affinity for female parent, Winter Brassica napus winter female parent, followed by affinity, Winter Brassica napus parental affinity to do the worst.4. Low temperature stress, Gas exchange parameters and the fluorescence of each material downward trend,Major changes in amplitude of strong cold varieties and distant hybrid of winter Brassica juncea rapa and winter Brassica rapa as female.
