| Abstract: | Dan299 is based on the tropical germplasm PN78599,using large groups,flooding Stress,early generation measured and directional selection technology,and obtained after continuous self-cross in 1991. After many-year experiments,the result showed that Dan299 had following advantages： high yield,water logging,strong resistance,high combining ability,high germination ratio and potential,good grain quality,suitable growth duration,and wide adaptability,etc. It is one of the widely used inbred lines. |
