Wilt Incidence

Wilt is the most serious disease causing irreversible losses and lethal damage to the crop in Bihar, Jharkhand, Orissa and the West Bengal states of Eastern India. Because of the existence of high pathogen variability, management of the disease using resistant cultivars will be a challenging task. For breeding resistant varieties, knowledge of pathogen variability in the particular crop area is essential.  In present study, fifteen isolates viz., Fu-9, Fu-10, Fu-27,Fu-32, Fu-42, Fu-49, Fu-63, Fu-72, Fu-73, Fu-74,Fu-75,Fu-84, Fu-86, Fu-87, Fu-97of Fusarium udum  obtained from wilt infected pigeonpea plants of Bihar, Jharkhand, Orissa and West Bengal of Eastern India were assessed for the phenotypic variation.  The isolates exhibited considerable variations in cultural and morphological characters viz., radial growth, mycelial color, sporulation, size and shape of macroconidia. Pathogenic variability on soil inoculated pot grown plants of pigeonpea resulted in 12.0 to 57.1 percent wilt incidence. The isolates also exhibited significant variations in symptoms like drooping of shoots, latent period, timing of fungal invasion, vascular clogging, drooping of shoots, and wilt establishment etc.  Based on the wilt incidence, the fifteen isolates were distinguished into pathogenic groups. Fu- 10, Fu-27, Fu-32 and Fu-49  were found highly pathogenic and predominantly causing the typical wilt symptoms of more than one 31% wilt incidence. The present study indicates the existence of variability among isolates of vascular wilt pathogen collected from Eastern region of India.

Wilt Incidence

Twelve Fusarium oxysporum f. sp. ciceri isolates were isolated from chickpea infected samples collected across different states of India. Pathogenic variability of twelve isolates was observed on seven chickpea cultivars viz., JG 62, Annigeri-1, Chaffa, CPS-1, K 850, L 550 and DCP 92-3. Among the twelve isolates APFOC-1 showed lowest wilt incidence 71.43 per cent and the isolate MPFOC-9 showed 100 per cent wilt incidence in all cultivars. The variability in morphological characters like size, shape, color of conidia and size, shape, color of chlamydospore were observed in all the isolates. The size of macroconidia varied from 9.23X2.53 ìm (WBFOC-12) to 19.3X5.52 ìm (MHFOC-8) with 2-4 septation. The size of microconidia varied from 4.4X2.93 ìm (MPFOC-9) to 8.26X4.2 ìm (MHFOC-8) with 0-1 septation. Macroconidia were sickle shaped and blunt ends with hyaline color. Microconidia were round to oval with hyaline color. Size of chlamydospore varied from 2.67 (UPFOC-11) to 8.24 (JKFOC-5). Chlamydospores did not show much variation with respect to shape and color. Based on the total number of spores observed per microscopic field, the twelve isolates categorized into four groups viz., poor sporulants, moderate sporulants, good sporulants and very good sporulants.

Macrophomina phaseolinais a serious pathogen of many crops. In the present studies, 65 isolates ofMacrophomina phaseolinafrom different agroecological regions of Punjab and Khyber Pakhtunkhwa provinces of Pakistan were analyzed for morphological and pathogenic variability. Regardless of their geographic origins, significant differences were detected among 65 isolates in their radial growth, sclerotial size, and weight as well as in pathogenicity. Sixteen isolates were rated as fast growing, 11 as slow growing, and the rest of the isolates as medium growing. Nine isolates were classified as large sized, 26 as small sized, and the remaining 30 isolates as medium sized. Thirty five isolates were ranked as heavy weight, 12 as low weight, and the rest of isolates were grouped as medium weight. Ten fungal isolates appeared to be least virulent, whereas eight isolates of diverse origin proved to be highly virulent against mungbean cultivars. The remaining isolates were regarded as moderately virulent. No relationship was found among the morphological characters and pathogenicity of the isolates. These morphological and pathogenic variations in various isolates ofM. phaseolinamay be considered important in disease management systems and will be useful in breeding programmes of mungbean cultivars resistant to charcoal rot.

Status Of Women

Crimes against women and girls have been increasing in recent years as reported by the National Crime Records Bureau. It becomes a serious social evil worldwide. The study has been tried to find out the trend of crimes against women for the period of the last ten years (2010-2019) in the states of eastern India i.e. Bihar, Jharkhand, Orissa and West Bengal. The study has been based on secondary data from the National Crime Records Bureau, Govt of India. The data have been extracted and analyzed to get the status of crimes in particular categories. The crime records of Bihar show an increasing rate of women assault cases. Jharkhand data shows that indecent representation of women has increased in recent years. In West Bengal Cruelty by husband is the most reported crime in West Bengal and it is also observed that rape cases were decreased in West Bengal continuously in the last ten years. It has been found that Orissa and Bihar are significantly high in crimes like women assault on the internet, an insult to the modesty of women, kidnapping and rape comparing other states of study. Cruelty by husbands and cases under the immoral traffic act had significantly higher in West Bengal compared to other states under study. The Dowry death and kidnapping and abduction are significantly high in Bihar. The different levels of crimes against women in different states not only indicates the status of women in the society and the law and order situations of that state but also it is a reflection of the socio-psychological aspects. Proper implementation of laws along with awareness of related issues, along with continuous monitoring can play a crucial role to minimize the overall crime scenario.

The Indian Skimmer is a globally threatened bird native to Bangladesh, India, Myanmar, Nepal, Pakistan, and Vietnam.  In India, it is more confined to the north, from Punjab through Uttar Pradesh, Madhya Pradesh to West Bengal, extending up to Odisha.  Earlier, the bird was known to breed only in Uttar Pradesh and Madhya Pradesh, we confirm here the breeding of the Indian Skimmer along the river Mahanadi near Mundali, Odisha, eastern India.  So, further monitoring at the breeding site and survey along the entire Mahanadi River are essential to understand the status of the Indian skimmer in Odisha.  The information will also aid in reassessing its global status and formulating conservation plans.

This paper presents the results of a study dealing with leaf morphological variability of Quercus robur L. 148 trees were sampled from 5 population across Serbia and 17 morphological traits were assessed. Interpopulation variability was confirmed by the results of the analysis of variance (ANOVA). A statistically significant (p <0.05) effect of population was obtained for most of the studied morphological characters. Intrapopulation variability was confirmed by statistically significant tree effects for all of the studied leaf characters (all p < 0.05). The results of the multivariate analysis of variance (MANOVA) confirmed a significant population and tree share in the total phenotypic variability (all p <0.05). By applying the canonical discriminant analysis (CDA), the first discriminant function accounted for 63% of the variability between populations and the second accounted for 20% of the population variability. The leaf area (AREA), specific leaf area (SLA) and surface area to perimeter ratio (ARPE) had the greatest effect on population differentiation (CDA). It is assumed that different environmental conditions affect population differentiation and that high intrapopulation variability is due to intraspecific variability.
