YLY 900（short for Y Liangyou 900）, was bred with the wide adaptability PTGMS line Y58S as the female parent and the strong indica restorer line R900 as the male parent, has developed root system, large panicles with plenty of spikelets, high seed setting rate, ideal plant type, suitable growth duration, wide adaptability, high and stable yield, good grain quality and multiple resistances to abiotic stresses, and made a new record for hybrid rice production with an average yield of 15.40 t/hm2 in a larger area of 6.84 hm2 in 2014. In this paper, the characteristics of YLY 900 are introduced and the high-yielding cultivation techniques are described in details.
