: Saline-alkali land widely distributes with large area in China. It is of great significance to select forage crops and rea-lize planting and breeding cycle in saline-alkali land to promote the development of herbivorous animal husbandry and the improvement of saline-alkali land in China. In this study, the plots with high salinity difference were selected from the coastal sa-line-alkali land in Tianjin (NaCl type) and the inland saline-alkali land in northwest Xinjiang (Na 2 SO 4 -NaHCO 3 type), respectively, and six field crops such as corn, sorghum, wheat, millet, soybean, and rapeseed with feed value were planted to determine the biomass, crude protein content, sodium and potassium ion content, and other indicators. The results were as follows. When the salt content was less than 1.82 g kg –1 and 2.00 g kg –1 in saline-alkali land NaCl type and Na 2 SO 4 -NaHCO 3 type, respectively. The biomass and crude protein yield of the crops were close to those of conventional cultivated land, suggesting that saline-alkali land in low salt content could be used as forage production base. When the salt content reached 2.49 g kg –1 in the Na 2 SO 4 -NaHCO 3 type saline-alkali soil, the biomass and crude protein yield of rapeseed were significantly higher than other crops. Thus, in the Na 2 SO 4 -NaHCO 3 type saline-alkali soil with salt content lower than 2.49 g kg –1 , rapeseed could be planted for fodder development and utilization. When the salt content in saline-alkali land of NaCl type and Na 2 SO 4 -NaHCO 3 type reached 3.63 g kg –1 and 4.42 g kg –1 , respectively. The biomass and crude protein yield of each crop was lower than 51.72% of that in conventional cultivated land, which made the utilization value of the cultivated land low. Therefore, it was recommended to use these saline-alkali land of NaCl type and Na 2 SO 4 -NaHCO 3 with high content salt and alkali after improvement. In the different plots of the two experimental sites, the enrichment of Na + in soil by rapeseed was significantly higher than the other crops at P < 0.05, and it also significantly reduced the total soil salt and Na + content. In this experiment, in plots with salinity of 1.82, 2.00, and 2.49 g kg –1 , rapeseed had the most obvious Na + enrichment effect. The enrichment of rapeseed on soil Na + was 39.45, 102.24, and 57.19 kg hm –2 respectively, accounting for 13.02%, 15.99%, and 8.94% of the Na + in the 0–20 cm cultivated layer soil, respectively. The improvement effect of rapeseed on saline-alkali land was significant. The above results provide a reference for the utilization of the saline-alkali land in China for the production of herbivorous feed raw materials, the promotion of the development of herbivorous animal husbandry, and the improvement of saline-alkali land.
：中国盐碱地分布广泛，面积大。盐碱地饲草作物的选择和种植繁殖周期的合理化对促进我国草食性畜牧业的发展和盐碱地的改良具有重要意义。本研究分别从天津滨海盐碱地（NaCl型）和新疆西北内陆盐碱地（Na2SO4-NaHCO3型）选择高盐度差异地块，种植玉米、高粱、小麦、小米、大豆、油菜等6种具有饲料价值的大田作物，测定生物量、粗蛋白含量，钠和钾离子含量以及其他指标。结果如下。盐碱地NaCl型和Na2SO4-NaHCO3型含盐量分别小于1.82 g kg–1和2.00 g kg–2时。该作物的生物量和粗蛋白产量与常规耕地接近，表明低盐盐碱地可以作为牧草生产基地。当Na2SO4-NaHCO3型盐碱地含盐量达到2.49 g kg–1时，油菜籽的生物量和粗蛋白产量显著高于其他作物。因此，在含盐量低于2.49 g kg–1的Na2 SO4-NaHCO3型盐碱地中，可以种植油菜籽进行饲料开发利用。当NaCl型和Na2SO4-NaHCO3型盐碱地的含盐量分别达到3.63 g kg–1和4.42 g kg–1。每种作物的生物量和粗蛋白产量均低于常规耕地的51.72%，使耕地的利用价值较低。因此，建议采用改良后的NaCl型盐碱地和高含盐高碱的Na2SO4-NaHCO3。在两个试验点的不同地块中，油菜籽对土壤中Na+的富集程度显著高于其他作物（P<0.05），同时也显著降低了土壤总盐和Na+含量。在本实验中，在盐度为1.82、2.00和2.49 g kg–1的地块中，油菜籽对Na+的富集作用最为明显。油菜对土壤Na+的富集度分别为39.45、102.24和57.19 kg hm–2，分别占0-20cm耕作层土壤Na+含量的13.02%、15.99%和8.94%。油菜对盐碱地改良效果显著。上述研究结果为我国盐碱地利用生产草食性饲料原料、促进草食性畜牧业发展、盐碱地改良提供了参考。

: Amino acids in cereal grains are important nutrients for both human and animals. Increasing the content of amino acids in the rice grain, especially lysine and other essential amino acids, plays a very important role in improving the nutritional stan-dard of people in the countries with rice as staple food. This paper reviewed some research progresses in the contents and compositions of amino acids in the mature grain of rice and their distribution in the different parts of a grain, the synthesis and metabolism of amino acids in the grain, the role of plant hormones in regulating the synthesis and metabolism of on amino acids, and the effects of environmental factors and cultivation practices on the contents and compositions of amino acids in the grain, and dis-cussed the existing problems and key points for future research. It merits further investigating the temporal (at different filling stages) and spatial (at different parts of a grain) distribution characteristics of the contents and compositions of amino acids in a grain during the filling, their physiological and biochemical mechanism, and cultivation regulation and its principle. Such a study is expected to gain new insight into the mechanism in the formation and distributions of amino acids in a rice grain, and explore a new way to increase the contents of amino acids, especially essential amino acids such as lysine, in milled rice.

: Longke 638S and Jing 4155S, developed by Yuan Longping High-Tech Agriculture Co., Ltd. in 2014, were two thermo-sensitive genic male sterile (TGMS) lines with disease resistance, high grain quality and combining ability for producing mid-season indica hybrid rice. In this study, we analyzed the blast resistance evaluation data from the regional trials of the Longliangyou and Jingliangyou hybrid rice varieties approved by the state from 2015 to 2019. Meanwhile, to provide theoretical basis for distribution and further improvement of these hybrid rice varieties, a genotyping panel containing 16 rice blast resistance ( R ) genes based on KASP (Kompetitive Allele-Specific PCR) technology was developed and used for molecular detection of these hybrid rice varieties. The results showed that 43.92% of Longliangyou and Jingliangyou hybrid rice varieties conferred moderate resistance to severity (HSPBS) was 3.3 and 4.7, respectively. These hybrid rice varieties carried different number of R genes, ranging from 3 to 7. The average number of R genes in each variety was 5.1. The distribution frequency of the five genes including Pia , Pita , Pi2 , Pi5 , and Piz were higher by more 50%, among which, it was 100% for Pia gene. In contrast, Pi9 , Pi35 , Pi36 , and Pb1 genes were not detected in Longliangyou and Jingliangyou hybrid rice varieties. With the increase of the number of R genes in the varieties, the mean values of IDI and HSPBS were generally decreased. In conclusion, we suggested that introduction of Pi9 into Longke 638S and Jing 4155s might lead to the further improvement of blast resistance of Longliangyou and Jingliangyou hybrid rice varieties.

: Soil salinization is an important limiting factor affecting seed germination, emergence, and growth of crop seeds. It is of great significance to explore the relieving effect of exogenous hormones on buckwheat seed germination and seedling growth under salt stress. This experiment was conducted to study the effects of melatonin (MT) and 2,4-epbrassinolide (EBR) on seed germination, seedling growth, antioxidant enzyme activity, and osmotic regulation substances of buckwheat varieties Xinong 9976 under different salt concentration stress using petri dish germination and pot germination. The results showed that salt stress increased the malondialdehyde (MDA) content, soluble sugar content, and antioxidant enzyme (SOD, POD, CAT) activities of buckwheat seeds and seedling leaves, decreased the germination potential, germination rate, and seedling rate of buckwheat seeds, and significantly decreased the germ length, radicle length, and seedling height of buckwheat seeds. MT and EBR soaking buckwheat seeds could effectively alleviate the harm of salt stress. Compared with the control, the germination potential, germination rate, and seedling formation rate of buckwheat seeds were increased by 14.9%–33.3%, 11.5%–27.3%, and 20.0%–46.2%, respectively. It significantly increased the radicle length, embryo length, embryo fresh weight, dry weight, seedling height, seedling fresh weight, and dry weight of buckwheat seeds, and significantly increased the soluble sugar content and the activities of SOD, POD, and CAT in buckwheat seeds and seedling leaves, and decreased MDA content. In conclusion, MT and EBR soaking can promote the germination and seedling growth of buckwheat seeds under salt stress, and improve the salt resistance of buckwheat by improving the protective enzyme activity of buckwheat seeds, reducing the accumulation of reactive oxygen species, and increasing the content of osmotic regulation substances.

: In this study, 252 plants and their parents of Fengshou 24 × Tongjiao 83-611 were genotyped by SNP160K DNA-chip. A high-density genetic linkage map with a total length of 3661.46 cM was constructed, composing of 5861 SNP markers. Seven QTLs of plant height were detected by inclusive composite interval mapping (ICIM), and each one explained 2.56% 10.41% of the variation in plant height. qPH-6-1 had the highest contribution rate of phenotypic variation and dominant effect, explaining 10.41% of plant height variation, and the additive and dominant effects are –1.72 and 18.94, respectively. The contribution rate of qPH-18-1 was the second, explaining 9.64% of plant height variation, but qPH-18-1 has the highest additive effect, reaching –12.42. 11 plants with qPH-6-1 and qPH-18-1 66.03 kb, containing eight genes. Combined with gene annotation and relative expression difference analysis, it was hypothesized that Glyma.18G279800 and Glyma.18G280200 might be associated with plant height of soybean. This study provides a molecular reference base and genetic basis for the improvement of soybean plant architecture.
