临沂塘稻品种资源的鉴定与利用评价

Assessment of Linyitangdao Rice Varieties and Evaluation of Their Utility

临沂塘稻是山东省临沂市古老的农家品种,分离类型较多。对所收集的临沂塘稻资源的农艺性状和品质性状进行鉴定与利用评价。结果表明:与临稻10号相比,3份临沂塘稻均表现株高偏高、剑叶长、抗倒性较差、丰产性差、整精米率偏低、加工品质较差,其中塘稻-2的食味品质差,而塘稻-3表现千粒质量高、抗倒性较好、出糙率较高,为香糯类型,生产上有一定的利用价值。

Linyitangdao rice varieties are ancient landraces native to Linyin City,Shandong Province,which originally consisted of many different types.In this study,we assessed agronomic and quality traits of three Linyitangdao varieties（Tangdao-1,Tangdao-2,and Tangdao-3）,using the rice variety Lindao 10 as the control.The results showed that three Tangdao varieties had poor agronomic and quality traits compared with Lindao 10.All three tested Tangdao varieties showed higher plant height,longer flag leaf length,lower resistance to lodging,and a lower milled rice rate than the control Lindao 10.On the other hand,Tangdao-3 displayed good performance for some agronomic and quality traits,although it had a relatively low head rice rate.Thus,Tangdao-3 could be used in rice production.
