Some superior cultivars, strains and genetic resources with desirable characteristics have been bred by utilizing Taigu genic male-sterilegene Tal, an available tool of wheat genetic improvement found at Taigu County, Shanxi Province, China in 1972, in wheat breeding programmes of NAU. Changjiang 8809, Changjiang 8863, Changjiang 8807, Changjiang 8810, Changjiang8862, TFSL037, etc. developed through recurrent selection during the development of the gene porl with improved resistance to scab in wheat, have high yield potential, semi-dwarf plant height, scab-resistance and tolerancet other diseases and waterlogging. High-yielding strains Changjiang 8877 (red-glume) and Changjiang 8877 (white-glume), selected from the progeny of the complex cross Ta Yangmai 4/P117//Ta Zongkang77-2 Ning 8017, showed 38.66% and 32.09% higher than the check cultivar Yangmai 5 in grain yields respectively. Changjiang 8802 with white seedcoat and resistance to pr(?)-harvest sprouting, Changjiang 8853 with early maturity and good quality, and Changjiang 8897 with early maturity, high spike grain weight and good quality were developed from the simple.crosses Ta Ningmai 3/Ning 7840, Ta Ningmai 6/S.

Correlation study and path analysis were made using data of the yield traits of 80varieties from the high fertility level regional tests of the North China Winter WheatRegions from 1983 to 1988. The results indicated that the most important factor forthe increase of grain yield in the North Winter Wheat Sub-region and the northernpart of the Huang- Huai Winter Wheat Sub-region is kernel weight per spike, with thenumber of spikes per mu ranking the second. The contributions of kernel weight perspike and the number of spikes per mu to the increase of production were nearly thesame with varieties from the Southern,part of the Huang-Huai Winter WheatSub-rigion, although the contribution of the latter seemed to be slightly larger. Sincelinear correlation studies are usually limited within certain ranges, different breeding ob-jectives should be elaborated for the different ecolgical conditions and breeding prac-tices of the different regions. It is therefore considered that to achieve the objectives ofbreeding for wheat varieties yielding more than 400kg per mu, the spikes per mushould be congruent with the kernels per spike while limiting the plarit height withina certain range. For the 3 particular regions, the following yield component structuresshould be involved in: 1). On the basis of sufficient spikes 450 thousand per mu, se-lect variety of larger spikes of high spike differentiation rate to increase kernel weightper spike, while short-straw and resistance to lodging variety may increase spikes permu to 500 thousand for the North Winter Wheat Sub-region. 2). High kernelweight per spike through the development of types with larger spikes, withoutincreasing the present number of spikes 400 thousand per mu for the Southern part ofHuang-Huai Winter Wheat Sub-region and 3). Either structure of 1 or 2 is adapta-ble for the northern part of the Huang-Huai Winter Wheat Sub-region.

对北方冬麦区1983~1988年高肥区域试验的80个参试品种的产量性状进行相关与通径分析。结果表明,北部冬麦区和黄淮麦区北片参试品种的增产因素主要是穗粒重,其次是亩穗数;黄淮南片参试品种的穗粒重与亩穗数对产量的贡献几乎相等,亩穗数稍大于穗粒重。鉴于直线相关是有一定范围的,结合各片的生态条件及育种实践,认为培育400公斤以上的高产品种,应该是限定株高在一定范围内,力争每亩穗数与每穗粒重相协调,穗粒重是进一步提高产量的关键,增加穗粒数是提高产量的突破口。北部冬麦区在保证足够亩穗数(45万左右)的基础上,选育穗分化速度快的大穗、多花类型品种增加穗粒数,提高穗粒重。而矮杆、抗倒类型品种也可以继续提高亩穗数到50万穗左右,以亩穗数夺高产;黄淮南片在现有亩穗数(40万左右)的基础上培育大穗型品种,增加穗粒数,提高穗粒重,黄淮北片两种途径均可采用。

Seed weight per spike was 46. 46%higher than that of CK. Low numbers of til1er per hm2 ofthehighspike weight resultedinlow spikenumbers perhm2,andledtolowyield.Causesleadingless tiller per hm2 were :①Atiller of high spike weihgt type wheat required more accumu1atedtemperature than that of CK;②The tiller of high spike weight type wheat was more senstive to low temperature than thatof CK, andtheadapationof tiller characteristics of highspikeweighttypewheat to ecologicalcondition was more narrow thanthat of CK。

对国内近年试验试种的穗重型小麦品种(系)群体发育动态研究表明:穗重型小麦单位面积冬季分蘖、春季分蘖、穗数和产量分别比对照(小偃6号和陕229)降低24.57%、37.21%、29.01%和10.87%;群体平均单穗粒重增加46.46%。分析认为,单位面积分菜数偏少的原因是:①穗重型小麦形成一个分蘖所需要的积温约为(96.54±19.1)℃,比对照品种多47%;②穗重型小麦的分蘖习性对低温反应敏感,对生态条件的适应范围小。
