Analysis of Seedling Quality and Yield of Indica Rice Restorer Lines
Using 9311 as the control(CK),the seedling quality and yield of 11 new indica rice restorer lines were compared and analyzed.The results showed that compared with CK,three restorer lines of 7W1207,8W227 and R1353 had high strong-seedling index,good seedling quality and strong rooting ability with higher values in plant height,stem base width,leaf age,leaf area per plant,root dry weight,root shoot ratio,root number,maximum root length and average root length.Compared with CK,except 6W1844 and 7W1519,the other nine restorer lines had a significantly higher yield per plant.Correlation analysis showed that the yield per plant was very significantly and significantly positively correlated with strong-seedling index and rooting ability,respectively.Therefore,during the breeding of restorer lines,the strong-seedling index and rooting ability can be used as important indicators for the early screening of strong restorer lines.Three restorer lines of 7W1207,8W227 and R1353 with good seedling quality,strong rooting ability and high yield per plant can be used for breeding in future.
