The F2 and F3 populations each of two ‘desi’ X ‘gulabi’ crosses, viz.JG-1260 X JG-4 and JG4 X PRR-1 along their ‘gulabi’ (JG-4) and ‘desi’ (JG-1260 and PRR-1) parents were studied at the Research station of J.N Krishi Vishwa Vidyalaya, Jabalpur ,during 1981-82. Highly significant differences were seen for days of flowering, maturity and plant height in both crosses, for pods per plant, seeds per plant and 100-seed weight in JG-4 X PRR-1 and for number of secondary branches only in JG-1260 X JG-4. The genotype variance was found to be predominant for days to flowering and maturity JG-4 X PRR-1. The major portion of genotypic variance was found additive in nature for days to flowering in both crosses, for plant height (JG-1260 X JG-4), number of seeds, pods per plant and 100-seed weight in JG-4 X PRR-1.

The present study based on 102 Jat and 48 Jatav married women reveals that the Jat community has a distinctly higher fertility than Jatavs despite the fact that both communities have essential know how of prevalent family planning measures. Socio-economic status of the couple is inversely proportional to some extent, with the fertility of women. Greater stress on family planning measures are suggested for all communities in rural areas.

Occurrence of high frequency of malignancy among the residents of this cotton growing region of Punjab and the presence of arsenic in the soil have necessitated the assessment of its genotoxic potential. This study has been carried out to test the genotoxicity of the soils from three sites, i.e. tube-well irrigated field, canal irrigated field and non-irrigated area, of Jajjal village of Talwandi Sabo Block of Punjab (India) using Allium assay. Bulblets (cloves) of Allium sativum were treated with 1, 5, 10, 20, 50 and 100% W/V of the soil extracts for 48h and tap water was used for control. In the chromosome aberration assay, root tip cells of Allium sativum were scored for the presence of various mitotic abnormalities. Bridges and fragments were scored as indicators of clastogenicity and laggards or vagrant chromosomes were indicators of spindle poisoning. Tubewell irrigated soils were observed to be more genotoxic than the other soil samples.

Levels of selenium (Se) in blood and the activity of glutathione peroxidase (GSH-Px) in the red blood cells were measured in two different populations of Australian Aborigines and three populations of Caucasians. Both values were significantly different among different groups. No sex differences were present in either Še or GSH-Px levels. Also, there was no correlation between Seland GSH-Px levels as is usually found in many animal species.

The investigations were carried out to determine energy utilization efficiency (Eu) in ten barley genotypes planted at a roW distances of 15 cms, 20 cms, 25 cms and 30 cms, respectively. Genotype DL-157 had an overall average maximum (1.56%) Eu, followed by RD-57 (1.45%). RD-137 exhibited very less (1.10%) Eu but yielded comparatively higher which is attributed to its higher energy utilization in the development of ear. Among row-spacings 20 cm showed significantly higher Eu and also yielded highest due to its efficient canopy architecture. Treatment combinations V3 S2, V3 S1 and V1 S2 utilized the maximum amount of solar energy resulted in higher dry matter (Dm) production and grain yields.

Cluster analysis was done through four methods: Single linkage, complete linkage, average linkage and weighted average linkage in order to determine the relationshipe of algal communities found to occur in fifteen localities of Madhya Pradesh occurring in some selected soil types. The localities have been divided into three categories cultivated, uncultivaked and garden soils of Gwalior, Bhopal, Rewa, Jabalpur and Pachmarhi. It has been found that soil algal communities are dependent upon the nature of soil.

Marker dots (MD) have been observed as extrachromatin bodies ranging from 1 to 2.5u in diam. in those cells which possessed some or the other chromosomal aberration. These dots have been observed to detach from chromosomes at any place and are also partly C-positive. G-banded metaphases have shown them to be present in the vicinity of chromosomes.

Geological, ecological and evolutionary factors have resulted in patchy habitats, creating disjunct distribution and endemism in fern biodiversity. With the creation of new habitats by manmade activities, these plants are now subject to survival by selection and adaption. The site of study, Mangalore is a city on the threshold of transition from a sleepy coastal town to a smartcity. It is located in the foothills of the central part of the Western Ghats. The fern flora of the region was studied.

Effect of temperature and red light interaction on spore germination of Ceratopteris thalictroides (L) Brong, Pteris vittata Linn and Tectaria codonata(Fee) C.Chr. occurring in Rajasthan has been investigated. It has been found that temperature enhancement upto a certain limit decreases the red light requirement of spore germination in these ferns. Spore germination has been found to be higher at 30°C temperature in comparison to the values recorded at 25°C temperature.

The weights of certain skull bones (mandible, maxilla, frontal, parietal, temporal, zygomatic and palatine) giving attachment to muscles of mastication have been studied in six young dogs. The weights are unequal on the two sides. On the basis of difference between the right and left total bone weights, and the number of individual bones heavier on a particular side, one side can be said to be dominant in four out of six animals studied. The left side is far more frequently dominant than the right side.

A field survey to study the prevalence of root knot nematode infection in vegetable crops was conducted in five districts of Chhattisgarh from December 2006 to November 2007. Soil and root samples from 42 farmlands belonging to 28 villages were collected using standard methods along with information on factors affecting root knot nematodes, such as, topographical features, soil texture and methods of irrigation and control. Isolation of the nematodes from the soil and root samples was done using Cobb’s Sieving and decanting method and modified Baermann funnel technique. Identification of nematodes was done microscopically by examination of perineal patterns of females. Population density of nematodes was determined per 10 gram of root sample and 200cc of soil sample.
