Crop plants

Rice (Oryza sativa L.) is one of the staple cereal crops of the world and it is one of the main sources of carbohydrates for nearly one-half of the world's population. So, an increase in rice yield to satisfy human needs is a pressing requirement. Agronomic characters such as high plant, length of panicle, length of flag leaf, number of seed per panicle, the weight of thousand rice, length and width of rice and tolerance to salt are the deciding factor for yield in rice.

The aim of this project was to select highly sensitive and specific aptamer capable of detecting Fusarium graminearum (Fg) and F. pseudograminearum (Fp) species. The aptamer-based testing allows early detection of fungal infection in the field. Fungi are known to change their activity and may often undergo genetic changes. The classic "gene for gene" theory explains the relationship between host plant cultivars and fungal pathogenic races.

Hybrid technology in many crops has contributed 20-30 per cent increase in the production and exploitation of heterosis through the development of F1 hybrids which has been recently deployed in rice with yield advantage of 20-25 per cent over best pure lines. The main aim of any plant breeding programme is to develop special high yielding hybrids and success of any plant breeding programme depends on the choice of appropriate genotypes as parents in the hybridization programme.

In agriculture, green manure is created by leaving uprooted or sown crop parts to wither on a field so that they serve as a mulch and soil amendment. The plants used for green manure are often cover crops grown primarily for this purpose.

The technique of drip irrigation is a solution of water saving for crops in the scarce region. Water is supplied on the soil surface directly, continuously and regularly by drippers and then it infiltrates into the cultivated soil layer to ensure that plants will grow and develop well.

Sweet sorghum is a new generation bio-energy crop with considerable tolerance to drought and salinity and amenable for multiple uses. Sweet sorghum has elicited the interest of breeder due to its capacity to provide renewable energy products, industrial commodities, food and animal feed. The sweet sorghum donor RSSV 313 is developed through a cross NSS223 x NARI 111 at MPKV, Rahuri through pedigree selection as identified and recommended as a donor parent in crop improvement programme based on specific physiological traits viz.

Jackfruit (Artocarpus heterophyllus Lam.), being a cross pollinated crop shows high variations in plant and leaf characters. Thus, present study was under taken to assess the morphological variations of plant and leaf characters among twenty genotypes under AICRP on Fruits, B.C.K.V., Mohanpur centre as per the descriptor developed by Bioversity International (IPGRI).

The development of fruits without fertilization is known as parthenocarpy. Parthenocarpy improves the fruit quality, processing attributes, production and productivity of vegetable crops like tomato, cucumber, watermelon etc. Absence of seeds can enhances the shelf life of the fruits, allowing a better conservation, fruit set in adverse climatic conditions, early and offseason production of vegetable crops. Therefore, it is important to ensure yield stability regardless of environmental conditions.

Alternative strategies are needed in pest management to protect crops from pests. Occurrence of epiphytic lactic acid bacteria (LAB) on crop plants, especially on sites that are selected by pests, may be associated with host selection by insects. We carried out laboratory investigations as well as screen house and field experiments to understand whether epiphytic LAB occur at oviposition sites of agricultural and horticultural crops, probably modulating pest abundance by attraction or repulsion. The diversity of such epiphytic LAB associated with insect oviposition sites is discussed.

Strong increase in the production of genetically modified organisms (GMOs) observed over the years has led to a consolidation of transgenic seed industries worldwide. The dichotomy between the evaluated risk and the perceived risk of transgenic use has defined their level of acceptability among different global societies. GMOs have been widely applied to agricultural commodities, among them the Roundup Ready™ (RR™) soybean line GTS 40-3-2 has become the most prevalent transgenic crop in the world.

Insect pests and pathogens (fungi, bacteria and viruses) are responsible for severe crop losses. Insects feed directly on the plant tissues, while the pathogens lead to damage or death of the plant. Plants have evolved a certain degree of resistance through the production of defence compounds, which may be aproteic, e.g. antibiotics, alkaloids, terpenes, cyanogenic glucosides or proteic, e.g. chitinases,b-1,3-glu-canases, lectins, arcelins, vicilins, systemins and enzyme inhibitors.

Saccharomyces cerevisiaehas been used as a model system to characterize the effect of cytochromebmutations found in fungal and oomycete plant pathogens resistant to Qo inhibitors (QoIs), including the strobilurins, now widely employed in agriculture to control such diseases. Specific residues in the Qosite of yeast cytochromebwere modified to obtain four new forms mimicking the Qobinding site of Erysiphe graminis, Venturia inaequalis, Sphaerotheca fuligi-neaandPhytophthoramegasperma.

Auxin influences growth and development in plants by altering gene expression. Many auxin-responsive genes have been characterized in Ara-bidopsisin detail, but not in crop plants. Earlier, we reported the identifi-cation and characterization of the members of the GH3, Aux⁄IAA andSAURgene families in rice.
