Development of 93 Zhong 6 and Its High Yield Cultivation

Compact plant wheat has the traits as higher head density, vertical leaf, lowerlight obstruct and higher photosynthesis rate. It is the ideal plant type for super-high-yield cultivation.The model of developing varieties with super-high-yield compact plant type, good quality,wide resistance and tolerance is proposed. The model is as facultative, mid-early maturity, plantheight 70~80cm, compact plant, mid-tolerability, higher spike formation rate, strong straw,well developed root, higher photosynthesis, disease resistance and good end use quality. The newvariety should be wide ranging adaptation and varied resistance. One of the major breeding objective is to select heavy spike and the mid-heavy spike type. Based on the current construction population of 500 kg/667 m2, increasing grains per spike and 1000 grain weight simultaneously,350000/667 m2 and 2. 5 grams per spike are recommended.The main points of cultivation for yielding 600 kg/667 m2 are as follows: enriching field fertilizer level, narrowing line space, increasing sowing seeds, making the population optimally. Ithas the similar function as increasing line space, decreasing sowing seed to get a optimum population for the normal varieties.
