优质早籼『湘早籼31号』的选育及应用 总被引:2,自引:0,他引:2
培育优质早籼品种 ,改善早籼品质 ,是解决南方劣质早籼严重压库与销售不畅局面的根本出路。围绕这一目标 ,我们育成了米质优、丰产性好、适应性强、熟期适中的早籼新品种湘早籼31号 (原名丰优早11号 ) ,并于2000年2月通过湖南省农作物品种审定委员会审定。这也是我省继湘早籼15号 (湖南软米 )之后 ,培育的通过省级审定的又一优质早籼新品种 ,目前正在全省大面积推广应用。一、选育经过1990年我们从省内外引进的40多份优质源材料中 ,筛选出了米质优、丰产性较强的舟903作为骨干亲本 ,于1991年与我省早稻材料配制了大… 相似文献

Red rice in the US is an aggressive weed that reduces the yield of rice and contaminates its grain. It is the same species as rice, which provides an opportunity for intercrossing. This genetic similarity complicates the management of red rice in fields and rice mills, but also indicates a potential for its use in rice breeding or niche markets. Physicochemical and cooking quality characteristics, which are important components of consumer desirability for rice, are virtually unknown for red rice. Thus, a survey of red rice accessions and rice × red rice crosses was conducted to characterize these traits. Grain amylose levels of most indigenous red rice accessions were similar to those of high amylose indica cultivars from Asia. Amylose levels in crosses were highly variable, ranging as low as those in medium-grain commercial rice to as high as those in long-grains. Alkali spreading value was generally greater in awned than in awnless red rice accessions and the aroma chemical, 2-acetyl-1-pyrroline, was detected in two red rice crosses. The generally high seed amylose levels in red rice indicate that its cooking quality would not be suitable for most common uses of US rice, but may be acceptable for niche uses. 相似文献

Brans of 23 traditional and 12 improved (both red and white) rice varieties in Sri Lanka were screened for anti-amylase and anti-glycation activities in vitro. Varieties which showed the highest inhibitory activities at screening were further investigated for anti-glucosidase and glycation reversing as anti-diabetic properties. The same varieties were studied for selected antioxidant properties. Significantly high anti-amylase and anti-glycation activities were observed for bran extracts of red varieties compared to white varieties at screening. Traditional red rice varieties, Masuran, Sudu Heeneti, Dik Wee and Goda Heeneti, exhibited significant and dose dependent anti-amylase, anti-glycation and glycation reversing activities. These varieties also showed marked antioxidant properties. It is concluded that brans of Sri Lankan traditional red rice varieties Masuran, Sudu Heeneti, Dik Wee and Goda Heeneti may be potential food supplements for diabetes. 相似文献

黄酮是中药中重要功能成分,具有较强抗氧化作用,能清除体内自由基,有提高免疫力,降血糖、血脂和血压,消炎的作用。对水稻中的黄酮研究较少,对高黄酮水稻资源的筛选更少有涉及。水稻黄酮主要为花青素与原花青素,花青素多存在于黑米中,原花青素多存在于红米中。通过测定985份资源的黄酮含量,并应用系统聚类中的WARD法,将黄酮含量分为高黄酮、较高黄酮、中等黄酮及低黄酮四类,其中高黄酮品种有4个。黄酮含量高能显著降低稻米蛋白质含量,增加稻米垩白度,但对其他指标影响较小。将优异资源与高黄酮水稻育种结合,全面提高一般色米的黄酮含量,可为糖尿病患者与"三高"(高血糖、高血脂、高血压)患者、肝功能不良者及免疫力较低者提供理想膳食素材。 相似文献

为明确种植水稻对陕北盐碱地土壤理化性质的影响,并筛选适宜陕北地区种植的耐盐渍水稻品种,进一步探索陕北盐碱地改良利用方式,以陕西省定边县堆子梁镇营盘梁村土地开发项目为契机,开展大田试验。结果表明,水稻种植可以显著改善盐碱地表层(0~20 cm)土壤的理化性质,表层土壤pH值和含盐量较未种植水稻前分别降低5.7%和25.5%,全氮、有效磷、速效钾和有机质含量则分别提高117.3%、45.9%、27.7%和67.3%。另外,种植不同水稻品种对盐碱地土壤酸碱度和含盐量影响基本无差异,但对表层土壤养分含量影响存在一定差异,水稻收获后,种植东稻4号的土壤全氮、有效磷含量最高,种植宁粳28的土壤有机质含量最高。隆优619产量较宁粳28、东稻4号分别提高4.96%和42.78%。 相似文献
