Pessimistic Interrelatedness Analysis of the Buckwheat Seed Output and Related Factors

摘要

Based on the two year comparison test results of the 9 sweet buckwheat varieties (Ordinary buckwheat), correlativity between seed output and interrelation characters were discussed by pessimistic interrelatedness analysis with some correlated material. It has been clarified that the series of the characters affecting on seed output from high to low are as below: height (x1), seed heavy /plant (x5), seed numbers/plant (X4), nod number/main stalk (x3), seed weight of a thousand seeds (x7), branching numbers/ main stalk (X2), life span days. The effect and ranks of those characters on seed output are reflected objectively in our research results, which could serve as a scientific theory and the method for buckwheat breeding and cultivation research.
