粤农73-204在甘蔗育种上的利用

Utilization of YN73-204 in Sugarcane Breeding

粤农出73-204是广东省农业科学院作物研究所在20世纪70年代初期,以粤糖57-423为母本、CP49-50为父本,筛选的优良育种亲本材料。具有大茎、高产、抗逆性强的农艺性状,在海南甘蔗育种场易开花,花粉量大,活力强,易于杂交。它是我国大陆甘蔗杂交育种中的高频应用亲本,也是为数不多既可作为父本也可做母本使用的杂交亲本之一。其中作为杂交母本应用较多,后代性状表现非常突出,已经选育出包括粤糖93-159、粤糖00-236和粤农89-759等优良甘蔗品种10多个。它是我国甘蔗育种中自主创新的重要亲本,也是甘蔗杂交育种的主要亲本之一。

YN73-204 was bred by Crop Research Institute, Guangdong Academy of Agricultural Sciences in 1970s, which parents were YT57-423 and CP 49-50, with the agronomic characteristics of large stems, high yield, strong resistance and agronomic traits, in Hainan sugarcane breeding station, which was easy to flower, with plenty and high vigor pollen, and also easy to hybrid. It become one of the most important sugarcane parents in China's Mainland and produced more than 10 varieties Such as YT93- 159, YT00- 236, and YN89-759.
