The highest value of photosynthetic rate and active photosynthesis duration in flag leaves could be increased in a range of 3.55% and 3 d by dressing N (112.5 kg/ha) at heading stage in hybrid rice variety cv.

Shanyou63 compared with control (no dressing N at heading), respectively. This resulted in the 7.93 percentage and 5.70 percentage increases of its leaf source capacity (LSC) and yield, respectively. Furthermore, genetic analysis of LSC was made by 4 × 4 incomplete diallel cross-design with 4 sterility lines and 4 resilience lines. The results showed that hB2 and hN2 in LSC for rice were higher than 70 percentage and 30 percentage, respectively, suggesting that it may be used as an index for selecting varieties with high photosynthetic efficiency in rice breeding. There were the similar effects of the additive and non-additive variations on LSC in hybrid rice. LSC was mainly influenced by sterility line and resilience interactions. The adding effect value of general combining ability for its parents may be used to forecast the phenotype of LSC in hybrid rice.展开更多

Wheat variety Ji 84-5418 has been bred on this model. The analysis results of high-yield and stability indicated that Ji 84-5418 was not only an aggregate of varied excellent characters,but a recombined biotype which could early differentiate spike and develop coordi-nately,and had better self-regulation ability and potential high productivity. Its yield is stable at 6000-8250 kg/ha.展开更多
