摘要
以2017—2023年通过非主要农作物品种登记的132个糖料甘蔗品种为调查对象,研究分析不同甘蔗亲本的选育效果以及登记品种的产量、宿根性和成熟期情况。结果表明,在调查育成的132个甘蔗登记品种中,亲本使用频率最高的是ROC22,其次是粤糖85-177、ROC25、CP72-1210、粤糖91-976、CP84-1198、粤糖93-159、粤农73-204、桂糖92-66、ROC10和ROC1。亲本来源主要是引进系列和粤糖/崖城系列,分别占比28.30%和26.42%。在产量分布及变化方面,1新2宿平均产量为102865.7 kg/hm^(2),产量变幅以90000.00~104999.99 kg/hm^(2)与105000.00~119999.99 kg/hm^(2)之间的品种最多;与对照相比,1新2宿产量增产幅度在5.00%~9.99%与10%~19.99%之间,分别占比22.90%和29.01%。在育成品种的宿根性方面,宿根蔗产量为新植蔗产量110.00%~130.00%的有8个,为100.00%~110.00%的有28个,说明大多数品种的宿根性挺好。育成品种的成熟期以早熟品种为主,占比46.49%。
From 2017 to 2023,132 sugarcane(Saccharum officinarum)varieties registered through non-main crop varieties were investigated,and the breeding effect of different sugarcane parents,as well as the yield,perennial roots and maturity of the registered varieties were studied.The results showed that ROC22 was the most frequently used sugarcane variety within the 132 registered sugarcane varieties,followed by Yuetang85-177,ROC25,CP72-1210,Yuetang91-976,CP84-1198,Yuetang93-159,Yuenong73-204 and Guitang92-66,ROC10,and ROC1.The main parental sources were imported series and Yuetang/Yacheng series,accounting for 28.30%and 26.42%respectively.In terms of yield distribution and change,the average yield of the first two days was 102865.7 kg/hm^(2),and the yield variation ranges from 90000.00 to 104999.99 kg/hm^(2) and from 105000.00 to 119999.99 kg/hm^(2).Compared with the control,the yield increase of New-1 and Su-2 were mainly between 5.00%-9.99%and 10%-19.99%,accounting for 22.90%and 29.01%,respectively.In terms of permanent rootedness of cultivated varieties,there were 8 sugarcane with yield from 110.00%to 130.00%of newly planted sugarcane,and 28 with yield from 100.00%-110.00%,indicating that most varieties had good permanent rootedness.The mature stage of cultivated varieties was dominated by early maturing varieties,accounting for 46.49%.
