Characteristics of Yield Component and Dry Matter Production of Three-line Rice Teyou 679 and Its High Yield Cultivation Technology
Field experiment was conducted to explore the characteristics of yield component and dry matter production of three-line rice Teyou 679 with Guiliangyou 2 and Teyou 63 as the control in 2011.Results indicated that compared with Guiliangyou 2 and Teyou 63,Teyou 679 revealed more effective panicles,less grains per panicle and harmony yield component,and showed less dry matter accumulation,greater dry matter transportation after heading and greater harvest index.Teyou 679 had equal yield with Guiliangou 2 and 12.7% more yield than Teyou 63.However,the differences of grain yield among varieties were not significant.Finally,high yield cultivation technology of Teyou 679 was proposed according to its characteristics of yield component and dry matter production.
