Abstract:

In this paper, 60 Tibetan Brassica juncea L. accessions as samples, 4 groups of agronomical traits (18 variables) including yield trait (5 variables), main stem traits (6 variables), branching trait (3 variables) and pod trait (4 variables) of Tibetan Brassica juncea L. were studied using canonical correlation analysis on. The results indicated that: (1) individual yield of Tibetan Brassica juncea L. was mainly dependent on number of pods and grain weight of each individual. Number of seeds in each pod had very small impact on individual yield; (2) pod trait was the most important trait effecting on yield of Tibetan Brassica juncea L. followed by branching trait and main stem trait successively; (3) there were strong interconnections between yield, main stem, branching and pod traits of Tibetan Brassica juncea L..
