| description | Yuenongsimiao is not only a conventional rice variety with high-resistance and excellent comprehensive traits, but also a good parent for high-quality rice breeding. The analysis of the characteristics of the derived varieties could provide a theoretical basis for high-quality rice breeding. With Yuenongsimiao (R1212) as the parent, there were 53 rice varieties approved or authorized, of which 43 passed national or provincial approval. These varieties were rich in type, including conventional rice, hybrid rice, aromatic rice and etc. To clarify the characteristics of varieties derived from Yuenongsimiao, the approved derived varieties were selected, and their yield, rice quality, disease and stress resistance performance in the year they participated in the national and provincial regional trials were compared and analyzed. It was found that the yields of these varieties in the regional trials were increased by 0.46%-10.98% compared with these of the control varieties. In term of quality indexes, except for the ungraded seedlings of Q Liangyouyuenongsimiao, both conventional rice and hybrid rice could reach high-quality standards. In terms of disease resistance, some derived varieties resisted blast and bacterial blight, while many derived varieties showed weak resistance to these two diseases. In the identification of lodging and heat resistance, the derived varieties showed strong lodging resistance. Furthermore, except Huiliangyouyuenongsimiao, other varieties showed strong heat resistance phenotypes. These derivatives generally possessed the characteristics of high-yielding stability, good rice quality, strong lodging and heat resistance, which fully reflected the"core"role of Yuenongsimiao as a high-quality rice parent. The main Yuenongsimiao derived varieties, such as Yuehesimiao, Yuejinnongzhan, Longjingyou1212, Jingliangyou1212, Longliangyou1212, Quanyouyuenongsimiao and Huiliangyouyuenongsimiao have been the main local varieties, with good promotion and application prospect in the approved area. |
