  rot resistance
Some of the foamed composites prepared in this work bear a remarkable resemblance to wood, a natural fiber reinforced foam composite, but with the advantages of flame and rot resistance.
      
At this stage the difference between the three fibre systems in rot resistance becomes slight.
      
Each fibre system suffers little microbiological degradation, thereby showing high rot resistance, when the respective oxy-fibres are modified by P-F treatment and also by vinyl grafting in a subsequent step.
      
High rot resistance (80-90% retention of tensile strength after soil burial test) and dye fixation (%) of as high as 86% were readily obtained for grafted jute fibres.
      
Percentage grafting, tenacity (g denier-1), dye fixation (%) and rot resistance (expressed as percentage retention of tensile strength of the fibre after a standard soil burial test) were evaluated and analysed.

The salted Chinese cabbage is a special type for salting processes of the Pak-Choi Chinese cabbage. Four representative varieties from the lower valley of Yangtze-Hwai river, i. e., Nanking Kao-Zhuon, Hanchow Pio-Keng-Bai, Kaochun Ma-Er-Dor and Yanchow Hwa-Yi-Da-Tsai, were chosen for a diallel crossing experiment according to Griffing's method one (model 1). The field experiments were held in Nanking in 1974 and in Nanking and Yanchow respectively in 1975.1. Generally, the yield, downy mildew-resistance,...

The salted Chinese cabbage is a special type for salting processes of the Pak-Choi Chinese cabbage. Four representative varieties from the lower valley of Yangtze-Hwai river, i. e., Nanking Kao-Zhuon, Hanchow Pio-Keng-Bai, Kaochun Ma-Er-Dor and Yanchow Hwa-Yi-Da-Tsai, were chosen for a diallel crossing experiment according to Griffing's method one (model 1). The field experiments were held in Nanking in 1974 and in Nanking and Yanchow respectively in 1975.1. Generally, the yield, downy mildew-resistance, virus-resistance and bacterial soft rot-resistance of the salted Chinese cabbage F1 all show the mid-type of their parents, and no significant differences between each pair of reciprocals. There are some crosses with heterosis and some with reciprocal effect, but some are not consistent between different years or locations. After comparison, Kao × Pio (of entire leaf type with white flat petiole), was selected for Nanking region, and Pio X Hwa and Hwa × Kao (of deeply flaky leaf type with white round petiole), for Zhangkian-Yanchow region because of their moderate disease-resistance and high yielding ability by transgressing upper parent 20.1-22.1%, 12.7-21.6% and 6.0-31.3% respectively.2. As for yield the significance of g.c.a. and of s.c.a. are consistent between two years, but the reciprocal effectsare not. There are greater and shifting s.c.a. for Kao and Pio, greater g.c.a. and stable s.c.a. for Hwa. These three varieties are all better parents, when used in crossing the reciprocal effect should not be neglected.3. In yield component of three selected crosses there are significant s.c.a. and r for Kao ×Pio and r for Pio×Hwa, but not for Hwa × Kao besides the significant g.c.a. for them. The g.c.a., s.c.a. and r all should not be neglected in the design of crossing because of different crosses having their own specialities.4. The estimates of heritability for yield in broad sense are about 76.7-81.7% indicating the possibility of high yielding crosses to be persistent from year to year.

本文旨在分析江淮下游酶白菜代表品种的杂种优势与配合力。产量、抗病性的杂种优势因组合、正反交而异。有些组合的表现还因年份、地点等环境条件而不同。评选出优势强而稳的高×瓢、瓢×花、花×高组合可供生产应用。亲本间在一般配合力、特殊配合力以及它们的波动程度上都有各自的特点,选配组合时对一般配合力、特殊配合力以及正反交效应都需注意。产量杂种优势利用的广义遗传力估计值为76.7—81.7%。

Stalk rot has been one of several major diseases of corn in the corn area in Shanxi province,since 1977.A serious yield losses from stalk rot were caused by the premature death of plants,by stalk lodging which res- ults in unharvestable ears,and by ear rots that develop on lodged plants. The yield losses were estimated by 15% to 20%. The pathogens were identified and known as Fusarium moniliforme var. Subglutinans and F.bulbigenum.The pathogenicity of the latter was stronger than the former. The stalk rot...

The yield losses were estimated by 15% to 20%. The pathogens were identified and known as Fusarium moniliforme var. Subglutinans and F.bulbigenum.The pathogenicity of the latter was stronger than the former. The stalk rot resistance of nine corn hybrids was determined and the differences of their resistance were quite significant.

近年来,玉米茎腐病在山西省玉米种植区已成为玉米主要病害之一,该病发生在灌浆期,表现整株青枯死亡,茎杆腐烂,倒伏。因此病造成的损失平均为15—20%。经分离鉴定,病原菌为 Fusarinm moniliforme var.subglutinans 和 F.bulbigenum,而且后者的致病力强于前者。本文还报道了玉米杂交种对茎腐病的抗性测定,证明杂交种间的抗性差异显著。

The peanut rotting-pod rate in different cultivars has evident genetic variation .The result of this experiment showed that the rotting-pod rate of F1 was closely related to parents.If both parents were susceptable to the disease, the hybrid F1 was also susceptable.If one parent was susceptable and the other resistant, the rotting rate of hybrid F1 would show in the middle of parents.The heritability ( h2 ) of resistance to rotting pod was low (range from 0.1531 to 0.4177), which...

The peanut rotting-pod rate in different cultivars has evident genetic variation .The result of this experiment showed that the rotting-pod rate of F1 was closely related to parents.If both parents were susceptable to the disease, the hybrid F1 was also susceptable.If one parent was susceptable and the other resistant, the rotting rate of hybrid F1 would show in the middle of parents.The heritability ( h2 ) of resistance to rotting pod was low (range from 0.1531 to 0.4177), which revealed that rotting resistance was a quantitatively related to polygenes.

在不同花生品种之间,烂果率存在着明显的遗传差异。试验表明烂果率的高低与杂种的亲本密切相关。如果双亲均为易烂果品种,则杂种F_1也易烂果。如果双亲之中有一个亲本为易烂果品种,另一方为抗烂果品种,则杂种的烂果率一般介于双亲之间。烂果率的遗传力不高(变动于0.1531到0.4177之间),这表明烂果率是一种数量性状,可能受控于微效基因。
