| 3. | Ril - 8 population is suitable for mapping with great different phenotypes in yield traits and quality traits
Ril - 8群体各系的综合性状也表现优良，在产量性状和品质性状都存在较大差异，是有关研究的良好的基础群体。 |
| 4. | The parents of ril - 8 are excellent germplasm in wheat breeding with large ear and good yield traits in chuan35050 and excellent yield traits in shannong483
其中，川35050是大穗材料，综合性状优良，山农483综合性状优异，都是在育种中有较高利用价值的材料。 |
| 5. | This indicated that interaction effects of qtls are important for yield traits . some sites of interaction effect qtls are also the sites of additive efffct qtls or linked with the sites
从加性效应、互作效应， qtlsrd连锁，环境的作用等诸方面来看，产量性状是由非常复杂的遗传体系控制的。 |
| 6. | Qtl mapping of yield traits was carried out by using molecular markers in this paper . the main methods and results are as follows : ( 1 ) a population of 131 recombinant inbred lines ( rils ) , ril - 8 , were created from the cross of chuan35050 and shannong483
本文对小麦产量性状进行了qtls作图，主要方法和结果如下： ( 1 )本研究创建了包括131个系的小麦rils群体? ? ril - 8 ，其组合为“川35050山农483 ” 。 |
| 7. | ( 3 ) all of the 131 lines of ril - 8 population and their parents were planted in four environments : environment 1 , taian 1999 ; environment 2 , taian 2000 ; environment 3 , taian 2001 and environment 4 , yantai 2001 . nine yield trait phenotypes were investigated in these four environments
( 3 )将ril群体的各个系及其亲本分别在4个环境下种植：环境1为1999年泰安，环境2为2000年泰安，环境3为2001年泰安，环境4为2001年烟台。调查了9个产量性状。 |
| 8. | ( 4 ) the results of qtl mapping indicated that the inheritance of yield traits was very complex , the explanation as follows : additive effects except for sterile spikelet number per spike ( ssns ) , qtls of additive effects were tested for all other traits , with 10 qtls for 1000 grain weight ( kgw ) . the large variance of the effect values and the contribution rate of qtls indicated that the effects are difference for different qtls
14 。 （ 4 ）通过对产量性状qtls作图，发现产量性状的遗传非常复杂，可以从4个方面说明：加性效应除不孕小穗数外，各性状均检测到了表现加性效应的qtls 。其中，在各环境联合分析下，检测到了10个千粒重qtls ，各qtls的加性效应值和对群体变异的贡献率也存在很大差异，说明不同的qtls不是等效的。 |
| 9. | Qtl mapping for the 9 yield traits was carried out using qtlmapper version 1 . 0 . the main results are as follows : using the combined test of the four environments , 39 qtls of additive effects distributing on 14 chromosomes were detected . the range of general contribution rate of additive effect qtls for different traits is 1 . 83 ~ 27 . 24 % , and the range of contribution rate of different single qtl is 1 . 06 - 8 . 93 %
利用qtlmapperversion1 . 0作图软件进行了产量性状的qtls作图，主要结果如下：在各环境联合分析下，共检测到9个性状的39个加性效应qtls ，涉及14条染色体，各个性状的总贡献率变化范围为1 . 83 27 . 24 ，单个qtl贡献率变化范围为1 . 06 8 . 93 ；共检测到9个性状的41对qtls互作位点，涉及用于分析的全部18条染色体，各个性状的总贡献率变化范围为1 . 26 36 . 15 ，单今互作效应的贡献率变化范围为1 . 20 13 . 30 。 |
