| Abstract: | The productivity and stability of five rice hybrid varieties(SHANYOU 63,D-You63,D-you 10, XIEyou 63,Ⅱ-32A×MINGHUL63) were evaluated by estimating their indices of productivity and stability, The results are shown as follows(1) S￣2di of the five rice varieties was not singnifisent, suggesting a good stability,(2) The indices of productivity and stability for the five rice varieties (SHANY you 63,D-you63,D-you 10 XIETyou63,Ⅱ-32A×MINhu63) were 101. 337, 97.978, 103.798, 96.087,99.341 respectively ,and compaed to the check SHANyou 63, the heterosis rates of the indices of productivity and stability are D-you 10(2.43%)D-you63 (-3.31%), XIEyou 63(-5. 18%),Ⅱ-32A×MINGHUI63(-1.97%),(3) The Weights of productiveity and stability of the five rice varieties are 67.71 and 32.29 respectively;(4) The This study analyzed The four rice varieties for heterosis intervals too, compared to The check SHAN Y you63. |
