摘要
分析１９９８年度全国温光型Ｃ４９Ｓ两系杂交小麦联试资料表明，温光型两系杂交小麦极显著地较对照增产，平均增产１１．１０％～２１．６２％。其产量的超标优势主要来源于穗粒数和有效穗优势，并以穗粒数优势起主导作用。其中，ＭＳＩ每６６７ｍ２产量可达６５５ｋｇ，对对照绵阳２６号增产６６．４％，比常规小麦平均增产２１．６２％。
Almost all wheat varieties are the restoring lines for C49S. The thermo-photo-sensitive C49S two-line hybrid wheat significantly increased the yield compared with the ckeck Mianyang 26, generally the average increased percentage was 11.1%-21.62% The heterosis of yield over check mainly stemmed from the superiority of grains per spike and effective spikes, and grains per spike played the important roles. The yield increment of two-line hybrid wheat MS1 averages 21.62% compared with the conventional wheat (the check), its yield could get 655kg per 667m2, which was 66.4% higher than that of Mianyang 26. The results revealed preliminarily the increasing yield potential of thermo- photo-sensitive two-line hybrid wheat.
