The identification and cloning of RNases has enabled the use of molecular techniques to characterize Sgenotypes in apple cultivars. To identify the S-alleles associated with self-incompatibility, allele specific primers were tested using PCR, evaluating eight apple genotypes. A total of 6 pollen incompatibility groups in apple genotypes were identified among eight accessions by PCR based S-allele typing analysis. Eight putative S-alleles (S1, S2, S7, S19, S21, S23, S24 and S26) were identified with S1S7, S1S23, S1S24, S2S26, S19S24 diploid and S1S21S24 triploid combinations that had not previously been identified from apple cultivars. The molecular allele typing system of Sgenotypes based on PCR is a useful and rapid method for identifying new S-alleles and incompatibility groups in apple and the present results enabled the characterization of eight appl...

There is an utmost need to manage diseases and to make sure a steady and constant supply of marketable produce for the burgeoning world population [1]. In disease management, indiscriminate use of pesticides has resulted in accumulation of toxic compound potentially hazardous to human health and environment and also in the build up of resistance to the pathogens [2]. Due to the side-effects of chemical pesticides, the sustainable crop production through eco-friendly pest management strategies is essentially needed in present scenario [3]. In order to manage these problems, an effective alternatives approach to chemical control should be employed and considering the cost of chemical pesticides and hazards involved, biological control of plant diseases appears to be potential, non hazardous, viable, ecofriendly and alternative approa...

Since antiquity man has been exploiting wild plant species as food and to sustain health. While few of these species have gradually been domesticated, many continue to remain wild while playing pivotal role in tribal food, feed and folklore medicine. India being among the most flora rich countries of the world is host to hundreds of wild plant species with established health benefits well known to the indigenous tribes and locals but remain largely untapped. However, growing awareness about bioactive phyto-compounds and their role in prevention and cure of modern human diseases and disorders is steadily bringing such underutilized plant species to a significant place in modern pharmaceutical and medical research. Considering such a scenario, the aim of writing this chapter is to highlight indigenous species of Indian North-Western Himalayan states and territories with respect to their health promoting attributes and potential application in the practice of alternative as well as mainstream medicine.

These traits were estimated as reducing sugars, non-reducing sugars and pyruvic acid in different photoperiod and temperature sensitive genotypes grown in long day, temperate agroclimate. Reducing sugars varied from 2.26% to 3.79%, non-reducing sugars from 2.97% to 4.29% and pyruvic acid from 1.73 to 11.33 µmol/ g fresh weight. The lowest reducing sugar content (2.26%) was found in OA-18-09 and OC-18-89 and about two-third of the germplasm (2.28% to 2.94%) was at par with them. Highest non-reducing sugar content (4.29%) was found in OA-18-27 with about two-third of the germplasm (3.41% to 4.42%) statistically at par with it. For pyruvic acid content (µmol/g fresh weight), significantly higher values were found in OB-18-58 (11.33) and OB-18-53 (10.48). The lowest content (1.73) was found in OC-18-75 with nine other entries at par.

Populations with the Aid of PCRBased Molecular Marker Marker assisted selection (MAS) using mitochondrial DNA based marker cytochrome b (cob) was integrated with phenotypic evaluation to isolate male sterile and maintainer lines from openpollinated onion varieties adapted to North Indian agro-climatic region. Cytotype (N/S) determination by cob marker followed by morphological and microscopic study of pollen discovered male sterile plants (Smsms) at frequencies of 0.015 in Punjab Naroya, 0.020 in Punjab Selection, and 0.006 in Punjab White. The progeny scoring of test-crosses between male sterile and N-cytoplasmic plants isolated the maintainers (Nmsms) at frequencies of 0.133 in Punjab Naroya, 0.231 in Punjab Selection and 0.182 in Punjab White. As a novel approach, Trait Recovery Programme was demonstrated to reduce the population size required to recover a male sterile plant by 91.08% in Punjab Naroya, 92.99% in Punjab Selection and 97.66% in Punjab White. For recovering a maintainer, 10% reduction in Punjab Naroya and 9.10% in Punjab Selection was calculated. However, no reduction was observed in Punjab White. This analysis also validated that in a randomly mating onion population, frequency of recessive ms allele squared is equal to the frequency of male sterile plants among S-cytotype and frequency of maintainers among N-cytotype (fms2 = fSmsms/fS = fNmsms/fN)....

It causes significant losses (up to 80 %) in seed as well as bulb crops. The synthetic fungicides are the only option available to farmers for its management, which in long run may result in resistance development in pathogen. So there is a need to find novel strategies for management of this disease, hence the present study was devised to evaluate the antifungal efficacy of plant extracts from eight medicinally important plant species. The test fungus S. vesicarium was isolated from symptomatic leaf samples and was identified by characteristics of spore from available literature. Methanolic extracts of selected plants at three different concentrations (0.1, 0.5 and 1.0 %) were evaluated against S. vesicarium using poison food technique under in vitro conditions. The results showed that all plant extracts exhibited statistically significant antifungal efficacy from each other (P < 0.05). But Origanum vulgare at 0.5 and 1 % concentration exhibited highest antifungal efficacy (68.23 % and 81.3 % respectively). The importance of the present study lies in that the oregano extracts had the potential to manage the disease under field conditions after isolation of bioactive molecule and development of proper formulation. To the best of our knowledge this is the first kind of study conducted, where oregano has been reported to be effective against plant pathogen.

In day to day life Nutraceuticals have received considerable attention because they are harmless, efficient and have potential nutritional value as well as therapeutic effects. Among natural dietary supplements, vegetables being low in calories are packed with vitamins, minerals, antioxidants and phytochemicals. They play an important role in the human diet and are rich sources of biologically active compounds which are very essential for human beings. Phyto-nutraceuticals include lycopene from tomato, curcumin from turmeric, carotenoids from carrot etc are very popular. Number of studies has proved that vegetables contain more health givin g ingredients as sugars, amino acids and vitamins have long been recognized for their health benefits to humans. As technology and research techniques are improving, other substances in vegetables that were previously ignored are getting the spotlight. Another active nutraceutical ingredients in vegetables are flavonoids. They can act as potent antioxidants and metal chelators. They also have long been recognized to possess anti inflammatory, antiallergic, hepatoprotective, antithrombotic, antiviral, and anti carcinogenic activities. Antibacterial activity has been displayed by a number of flavonoids. Flavonoids, especially quercetin, has been reported to possess antidiabetic activity. The potential great number of phytochemicals including some of the vitamins, flavonoids, terpenoids, carotenoids, phenolics, phytoestrogens, minerals and antioxidants in vegetables are used as alternative preservative agents for controlling postharvest physiological disorders or microbial pathogen injuries of vegetables in the food industry. Moreover, these natural compounds have become interesting candidates not only for plant protection but also human and animal health protection from fungal and bacterial diseases because of their lower toxicity or absence of toxicity. The present review will focus on Nutraceutical value of vegetables.
