Abstract
[Objective] The aim was to supply theoretical basis for the popularization and cultivation of Lvfeng 20. [Method] The breeding, characteristics and supporting high-yield cultivation techniques of Lvfeng 20 were introduced, and its production potential and popularization value were discussed. [Result] Lvfeng 20's whole growth period is moderate with 138 d. Its effective panicles is 252 × 104 per ha, plant height 119.2 cm, panicles length 24.4 cm, total spikelets per panicle 174. 3, filled grain rate 75.4% , 1 000-grain weight 27.3 g. It has high yield and good quality meeting the national standards for high quality rice with 3 grade. It is susceptible to rice blast and high susceptible to bacterial blight. It has strong resistance to lodging. [ Conclusion] Lvfeng 20 has characteristics of moderate plant shape, dark green leaf, luxuriant growth potential, high yield, good quality and strong resistance to lodging, so it has better popularization and application foreground.关键词
