通过分析,供试的三个 T 型杂种小麦在根,茎、叶的生长量,亩蘖数.成穗率,抗寒性等生长特性和光合面积,光合强度,希尔反应,伤流量,干物质积累及向穗部运转能力等生理特性方面都具有超亲或一般优势。杂种的生物学产量(总干物重积累)较高,具有较强的杂种优势。但由于恢复系的恢复力不强,杂种不孕小穗和小花多,穗粒数少,影响杂种的产量下降。供试的三个杂交种在经济产量上都没有超过产量较高的亲本或对照。由此,要培育高产杂交种,必须要选育出经济性状良好和恢复能力强的恢复系,以及经济性状与配合力均好的不育系,以提高杂种的结实率和经济产量。
The growth, photosynthetic rate, photosynthetic rate, Hill reaction, traumatic flow rate, photosynthetic rate, photosynthetic rate and photosynthesis of three T - Dry matter accumulation and panicle ability to run and other physiological characteristics have super-pro or general advantage. Hybrid biological yield (total dry matter weight) higher, with strong heterosis. However, due to the resilience of restorer system is not strong, hybrid spikelets and florets, spikelets less, affecting the yield of hybrids decreased. All three hybrids tested did not exceed the economic yield of the higher-yielding parents or controls. Therefore, to breed high-yielding hybrids, it is necessary to breed restorer lines with good economic traits and recovery ability as well as sterile lines with good economic traits and combining ability to improve the seed-setting rate and economic yield of hybrids.
