The North-eastern (NE) India, comprising of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura, possess diverse array of locally adapted non-Basmati aromatic germplasm. The germplasm collections from this region could serve as valuable resources in breeding for abiotic stress tolerance, grain yield and cooking/eating(More)
Introduction: Raman spectroscopy (RS) has been proposed as a candidate analysis system for missions to Mars and, more recently, as a potential mineralogi-cal analysis system for Venus [e.g., 1,2]. This technique has several distinct advantages over other spec-troscopic techniques that have been used on past missions , specifically including the capability(More)
(blue [3]) with terrestrial standard samples (red). Introduction: The extreme Venus surface temperature (740K) and atmospheric pressure (93 atm) creates a challenging environment for future lander missions. The scientific investigations capable of Ve-nus geochemical observations must be completed within several hours of the landing before the lander will be(More)
Fusarium solani is the important pathogen causing wilt disease of guava in India. In the present investigation six representative isolate of Fusarium solani, collected from different places of India were subjected to analysis of genetic variability in terms of Carboxylesterases isozyme pattern and DNA polymorphism using RAPD-PCR. Pattern of Carboxylesterase(More)
Hill rices (Oryza sativa L.) are direct seeded rices grown on hill slopes of different gradients. These landraces have evolved under rainfed and harsh environmental conditions and may possess genes governing adaptation traits such as tolerance to cold and moisture stress. In this study, 64 hill rice landraces were collected from the state of Arunachal(More)
Overview: Detection of water and carbon is important in order to support existence of life on other planets. Water has been detected on Mars and Moon in the form of ice and in hydrous minerals. Among the various techniques to detect water, ice, and H 2 O/OH bearing minerals, Raman spectroscopy stands out as providing distinctive spectra for unambiguous(More)
Swell–shrink soils generate wide and deep cracks, generally considered undesirable for crop husbandry. However, there is a lack of information about the management options available to reduce formation of wide and deep cracks in such soil. Therefore, the present study was conducted on an Entic Chromusterts. The results revealed that width (mm) and depth(More)
There are errors in the seventh sentence of the Abstract. The correct sentence is: Population structure analysis revealed that NE Indian aromatic rice can be subdivided into three genetically distinct population clusters: P1, joha rice accessions from Assam, tai rices from Mizoram and those from Sikkim; P2, aromatic rice accessions from Nagaland; and P3,(More)
