Cadmium（Cd） contamination in rice has been a hot topic of research because of its potential risk to human health. In this study, a double haploid（DH） population derived from Zhongjiazao 17（YK17）（an early-season indica cultivar）×D50（a tropical japonica cultivar） was used to identify quantitative trait loci（QTLs） associated with Cd concentration in brown rice（CCBR） and Cd concentration in milled rice（CCMR）. Continuous and wide variation for CCBR and CCMR were observed among the DH population. Correlation analysis revealed a positive and highly significant correlation between the two traits. A total of 18 QTLs for CCBR and 14 QTLs for CCMR were identified in five different pot and field trials. Two pairs of QTLs for CCBR（qCCBR2-1 and qCCBR2-2, qCCBR9-1 and qCCBR9-2） and one pair of QTLs for CCMR（qCCMR5-1 and qCCMR5-2） were detected in multiple trials. The alleles increasing CCBR at the qC CBR2-1/qC CBR2-2 and qC CBR9-1/qC CBR9-2 QTLs were contributed by YK17 and D50, respectively, whereas the D50 allele at the qCCMR5-1/qCCMR5-2 QTLs increased CCMR. Eight pairs of QTLs for CCBR and CCMR, qCCBR2-2 and qCCMR2-2, qCCBR3 and qCCMR3, qCCBR4-2 and qCCMR4-1, qCCBR4-3 and qCCMR4-2, qCCBR4-4 and qCCMR4-3, qCCBR5 and qCCMR5-2, qCCBR7 and qCCMR7, and qCCBR11-1 and qCCMR11-2, co-localized on chromosomes 2, 3, 4, 5, 7, and 11, respectively. For all of these QTL pairs, except qCCBR5/qCCMR5-2, the additive effects came from YK17. In addition, four CCMR QTLs showing significant additive×environment interaction and two pairs of CCMR QTLs with bi-allelic epistatic interactions were identified. The results of this study could facilitate marker-assisted selection of breeding rice varieties with low Cd accumulation in grain.

Elongations of coleoptile and mesocotyl are related directly to rice seedling establishment in soil and height of plant is related to lodging in rice production. Twelve typical rice cultivars with different lengths of coleoptile and mesocotyl （long, medium and short） were selected by screening the lengths of coleoptile and mesocotyl in 1500 accessions. The seedling establishments of these typical cultivars were compared under the combinations of different sowing depths and flooding durations, and two semi-dwarf varieties （G140, Zhong 96-21） with good seedling establishments and optimum mesocotyl lengths were found. The length of mesocotyl was completely fitted negative binomial distribution and the length of coleoptile was nearly fitted Iognormal distribution. Analysis of the relationships among mesocotyl, coleoptile, seeding depth, flooding duration, and their interactions to seedling establishment percentage showed that there existed significant relations among mesocotyl, coleoptile, mesocotyl x coleoptile, seeding depth, flooding duration and mesocotyl x sowing depth in the experiment for seedling establishment.

以高直链淀粉及突变体材料Goamy2及其野生型亲本Ilpumbyeo米粉为材料,比较了它们在理化性质和糊化特性上的差别,并通过体积排阻色谱(Size Exclusion Chromatography,SEC)分析其水溶性和不溶性淀粉组成结构差别。从冷水溶性成分来看,Goamy2主要以小分子DP141～DP2(DP为聚合度)为主,而Ilpumbyeo中带分支的链DP4100～DP64也就是相对大分子所占的比例较高,达到33.3%。从热水溶性淀粉成分来看,突变体Goamy2直链淀粉和支链淀粉的比例大致为4∶1,而Ilpumbyeo直链淀粉和支链淀粉比例大致为1∶1。至于两个材料的热水溶性支链淀粉链长分布,长短链比例差别较大,Goamy2长短链比率为0.67,而Ilpumbyeo为0.32。从热水不溶性成分来看,两个材料均以支链淀粉为主,直链淀粉所占的比例很低,均不到5%。热水不溶性支链成分的链长分布中,野生型亲本Ilpumbyeo以短链为主,短链所占的比例高达72.5%,而突变体Goamy2短链和长链几乎各占一半。

20世纪60年代中期,日本率先开展了水稻品种抗稻瘟病基因分析的研究工作,鉴定了最初的8个抗性位点上的14个基因,并建立了一套抗稻瘟病基因分析用的鉴别体系(JDCs,Japanese differential cultivars),随后,国际水稻研究所和中国等产稻国也逐渐开展了水稻稻瘟病抗性遗传的系统性研究。截至2007年12月,已至少报道了58个抗稻瘟病位点共67个主效基因。这些基因成簇地分布于除第3染色体外的所有水稻染色体上,其中,66个为显性基因,1个为隐性基因,包括Pi-b、Pi-ta、Pi-z5、Pi-zt、Pi-9、Pi-d2、Pi-36和Pi-37等8个已被克隆的基因(Pi-z5、Pi-zt和Pi-9同为Pi-z基因位点上的复等位基因)。还讨论了合理利用抗性基因等问题。

利用60个水稻SSR标记,对来自国内外的370份香稻材料的遗传多样性进行了比较分析。结果共检测到361个等位基因,每个位点的等位基因变幅为2～10个,平均Nei基因多样性指数(He)为0.663,变幅为0.104(RM308)～0.885(RM2634)。籼粳亚种间的遗传多样性具有明显差异,籼稻的等位基因数和Nei基因多样性指数均高于粳稻。地方品种的遗传多样性高于选育品种,选育品种等位基因数仅为地方品种的86.5%。分子方差分析表明,香稻材料中总变异的43.08%是由于亚种间的遗传差异引起的。不同稻区的遗传分化程度总体介于1.69%～14.40%之间。其中,华南与西南、华中与西南地方品种间遗传差异的分化程度达显著水平。聚类分析将参试材料明显分为籼粳两大类,同时地域相同(稻区)、相邻省份的香稻材料基本归为同一类群。
