Abstract:

【Objective】The objectives of this study were to investigate the growth characteristics during the period from sowing to elongation and from anthesis to maturity in wheat cultivars (varieties), and to explore the possibility of breeding new cultivars with the feature of rapid growth at both early and late stages to achieve high yield and early maturity under late sowing condition in the middle and lower reaches of the Yangtze river. 【Method】 In the seasons of 2012-2013 and 2013-2014, experiments were conducted to compare leaf number, stem and tiller number and the parameters of grain filling among 18 new wheat lines and cultivars for screening the cultivar with rapid development at both early and late growth stages. In the season of 2014-2015, the differences of stem and tiller number, leaf area index (LAI), dry matter accumulation, yield and yield components were analyzed among Yangmai 16 and other 4 cultivars under the conditions of the normal (5th Nov.) and late (19th Nov.) sowing time to clarify the growth mechanics of high-yield about Yangmai 16 with rapid development at both early and late growth stages under late-sowing treatment.【Result】 Fu F101 showed a rapid development at early growth stage with a significantly higher number of leaves and tillers (before winter and during winter period) than Zhen 10216 in the 2012-2013, Ning 09-118 and Zhen 10216 had longer grain filling and rapid development at late growth stage with higher maximum grain filling rate (Gmax) and mean grain filling rate (Gmean) thus higher grain weight than other cultivars. The 2013-2014 trial showed similar results with Fu F101 performing rapid development at early stage and Zhen 10216 at late stage. Yangmai 16 produced even more tillers than Fu F101 before winter and similar tillers to Fu F101 during winter period. Meanwhile, both Gmean and Gmax of Yangmai 16 were similar to Zhen 10216 with Gmax being more than 2.0 mg/(grain·d). LAI, stem and tiller number and dry matter accumulation of Yangmai 16 in winter period were significantly higher than Ningmai 13 and other cultivars. In 2014-2015 trial, the yield of Yangmai 16 was lower than Yangmai 22 and similar to Yangmai 20, Yangmai 23 and Ningmai 13 under normal sowing time. However, under late sowing, the yield of Yangmai 16 was significantly higher than Yangmai 20 and Ningmai 13 and had the lowest yield reduction (5.2%) compared to other cultivars.【Conclusion】Significant differences were found among varieties in the rate of development at early and late growth stages. The rapid development at both early and late stages of Yangmai 16 makes it an excellent variety with not only a reasonable yield under normal sowing date but minimum yield reduction under late sowing. In summary, rapid development at both early and late stages can be used as a key criterion for selecting wheat varieties suitable for late sowing.
