摘要
改良新品种对提高伊拉克小麦产量具有重要作用。Garmian地区作为一个半干旱地区,由于当地品种在一段时间内持续减产,小麦产量极低。该项目是在Garmian农业研究目录下进行的,旨在通过2009年至2013年的四次田间试验开发新品种。在选择阶段,筛选出兼性冬小麦观察苗系(16th FAW-WON-IR)50个品系,并筛选出3个优系(SL1;CH75479/SARDARI-HD74,SL2;CATBERD/CNO79*2/HEF1,SL3;ID800994.W/VEE/5/CA8055/4/ROMTAST/BON/3/DIBO//SU),选择开花期和株高进行三个比较阶段的田间试验。多年平均,该项目的结果显著证实,所选的两个品系(SL1和SL2)在粮食产量方面优于当地对照(Aras;2.83 t h-1)约50-60%(P<0.001)(P<0.001),旗叶面积越宽,籽粒灌浆期吸收的CO2越多(P<0.01),优势基因型(SL1和SL2)随后获得鉴定资格,并由伊拉克国家农业品种记录和保护委员会正式发布(参考号192,日期为2018年11月21日)为新品种,即Kalar1(SL1)和Kalar2(SL2)。
Kalar1 and Kalar2, newly released wheat varieties for cultivation under rain-fed conditions
Improving new varieties plays an important role to increase the productivity of wheat grain yield in Iraq. Garmian region as a semi-arid area is extremely suffering with low wheat yield production as a result of continuing yield potential reduction of the local cultivars over the time. This project was conducted at the Directory of Garmian Agricultural Research to develop new cultivars through four field trials from 2009 to 2013. In the selection phase, 50 lines of Facultative and Winter Wheat Observation Nurseries (16th FAWWON-IR) were screened, and three superior lines (SL1; CH75479/SARDARI-HD74, SL2; CATBERD/CNO79*2/HEF1, and SL3; ID800994.W/VEE/5/CA8055/4/ROMTAST/BON/3/DIBO//SU) to the best local check (Aras) for grain yield, thousand grain weight, anthesis date and plant height were selected for testing in three field trials of comparison phase. Averaging over years, the results of this project significantly confirmed that two of the selected lines (SL1 and SL2) performed superior (4.24 and 4.73 t h-1, respectively) to the local check (Aras; 2.83 t h-1) with regards to grain yield production by about 50-60% (P < 0.001). This superiority of the selected lines compared to the local check was due to significant longer spike through increasing grain number (P < 0.001), and wider flag-leaf area which leads to assimilate more CO2 to the grain during grain filling duration (P < 0.01). Based on these results, the superior genotypes (SL1 and SL2) were then qualified for identification and officially released (Reference Number 192, dated November 21, 2018) as new cultivars namely Kalar1 (SL1) and Kalar2 (SL2) by the National Committee for Recording and Protecting Agricultural Varieties in Iraq for the climate of Garmian region.
