Callus induction response was evaluated with different four levels of 2, 4-D (1.0-2.5mg/l) and Kinetin (1mg/l). Among four combinations (Treatments) MS + 2,4D + Kinetin (2.5 + 1.0 mg/l) (T4) showed more significant growth (90%) of callus as compared to other three combinations viz. (T1) MS + 2,4D + Kinetin (1.00 + 1.00 mg/l) (50%), (T2) MS + 2,4D + Kinetin (1.5+1.00mg/l) (60%) and (T3) MS + 2,4D + Kinetin (2.00 +1.00 mg/l) (60%). Study revealed that as concentration of 2,4D increases then growth of callus also increased.

LC1, LC2, LC3 and LC4 collected from Savana, Wai, Kapara and Wakodi villages of Yavatmal district were used for RAPD analysis for assessment of genetic diversity by using five RAPD primers. The SDS-PAGE protein pattern profile was also resolved. Twenty amplicons were found to be amplified from which 55% were polymorphic and 45% were monomorphic across the local cultivar. The electrophoresis pattern of protein fractions were found to be directly related to the genetic background of the proteins and can be used to identify genetic makeup. Total 26 bands were expressed with different intensity. The 110 KDa and 41 KDa protein bands were unique in LC1 and LC4 respectively whereas 66 KDa protein band was common in all landraces. A Considerable variation in protein banding pattern was observed in four landraces which is localized from different villages of Yavatmal district of Maharashtra.

After exposed to heat stress an increment in proline and GB content was noticed in thermo-tolerant wheat genotypes and at 40⁰C 2 h and 46⁰C 3 h stress treatment the levels dropped in thermo-susceptible genotypes. RWC, chlorophyll ‘b’ content significantly declined with steady increase in lipid peroxidation. Heat stress induces the activity of all five ROS scavenging enzymes. However, heat inactivation of all five antioxidants observed at 46⁰C 3 h stress in all wheat cultivars. Wheat genotypes NIAW-34, AKAW-4627 and NIAW-917 found to be stable. Heat stress increases GB content with higher activity of all five antioxidants could probably ameliorate the adverse effect.

The level of total phenol content and the activity profile of chitinase, PAL and β-glycosidase significantly increased in both blast-resistant and susceptible rice genotypes with comparatively higher level induction Tetep, NLR-20104 and Swarnadhan the blast-resistant genotypes. The antioxidative enzymes were comparatively higher in the leaf samples of blast-resistant genotypes recording highest increase in NLR-20104 and KJT-5. The constitutive levels of total phenols and activity of defence-related and antioxidative enzymes in the control leaf samples differed among the genotypes and were even higher in the two blast susceptible genotypes (EK-70 and Chimansal). However, th...

The amplification genomic DNA with two SSR markers RM124 and RM224 were also performed for identification of blast resistance and susceptible genotypes. The activity of chitinase, PAL and β-glucosidase of post pathogen-infected leaf samples increased significantly in all rice genotypes, thought the increase was comparable less in to blast susceptible genotypes Chimansal and EK-70. The activity of antioxidative enzymes was comparatively higher in the infected leaf of blast resistant genotypes recording highest increase in NLR-20104 and KJT-5. The activity of defense-related and antioxidative enzymes in the disease-free leaf samples differed among the genotypes and was even higher in the two blast susceptible genotypes. RM144 and RM224 SSR primers clearly amplified in blast resistant KJT-5, NLR-20104, KJT-2, Tetep genotypes whereas RM144 missing in susceptible Chimansal but prominently present in susceptible genotype EK-70. This study revealed that higher level of induction of defense-related and antioxidative enzymes and presence of specific

RHRG-6083, TAG-24, TG-60(LC), Karad-4-11, SB-XI, RHRG-6097, RHRG-6021, and RHRG-6055 were subjected to moisture stress by withholding irrigation for 15 days in pot culture experiment in order to evaluate its effect of on RWC , proline accumulation, soluble proteins, chlorophyll content and activities of superoxide dismutase (SOD), peroxidase (POX), glutathione reductase (GR) and lipid peroxidation (MDA).The levels of proline, soluble protein and the activity of all four antioxidative enzymes were found to be increased with MDA content in all genotypes of groundnut during water stress, however the chlorophyll and RWC content were found to be decreased. This study revealed that under water stress condition SB-XI, TAG-24 and RHRG-6021 showed higher increase of proline content and activities of antioxidative enzymes with lower reduction in RWC and chlorophyll. These three genotypes are stable during stress and seems to be ...

Artificial stress induced by withholding irrigation water at critical growth stages in rabi sorgh... more Artificial stress induced by withholding irrigation water at critical growth stages in rabi sorghum cultivars in a pot culture experiments led to an increase in the contents of proline and reducing sugars, however in vivo nitrate reductase activity declined. The proline content increased significantly in all the six cultivars with the corresponding decline in RLWC. Proline accumulation was highest at seedling stage and declined at later growth stages. Higher leaf proline accumulation in Mauli, CSV-14R and Sel-3 and minimum decline in in vivo NR activity and non-reducing sugars under both minus and plus KNO3 assays under control as well as under stress condition suggested tolerance of these cultivars under stress at various growth stages. The cultivars such as Phule Yashoda, Swati and SPV-86 recorded maximum reduction in in vivo NR activity and also comparatively lower accumulation of proline and hence are categorized as susceptible ones.

The soil sample was collected and attempted to isolate the Rhodococcus spp. on selective medium. The Rhodococcus spp. showed profuse growth in a medium containing 0.1 % urea and slightly less profuse growth on the medium containing 0.1 % CDU as a sole nitrogen source. The CDU contained ammonical and nitrate nitrogen 19.6 and 13.0 %, respectively. It thus appeared that the soil microorganism Rhodococcus spp . can utilize the CDU probably suggesting that microorganism could have enzymatic activity which can degrade CDU. The activity of nitrate assimilating enzyme was assayed from the leaf tissues at four critical stages showed that the treatment T 5 (100 % CDU) recorded highest activities of NR, NiR, and GS, high nitrogen up take, high NUE an...

The analysis revealed significant differences in the content of moisture (7.04-12.09%); crude protein (17.62-25.45%); crude fat (1.41-2.93%); carbohydrate, (49.68-60.48) and ash (3.05-5.00%). Limiting amino acids viz tryptophan and methionine were ranged from 0.56-1.03 and 0.70-1.16 g/16g N respectively. The genotype PT-012-16 was found to be high in protein (25.45%), whereas the genotype PT-04-391 recorded the highest fat (2.93%). The higher tryptophan was observed in genotype PT-012-26 (1.03 g/16g N) whereas highest methionine content was recorded in PT-012-6 (1.16 g/16g N). All genotypes under study were found to be deficient in both the limiting amino acids tryptophan and methionine when compared with the WHO/FAO reference standard. This study revealed that the genotypes PT-012-9, PT-012-16 and PT-012-23 were found to be promising for future breeding programme for nutritional quality improvement.

Mechanical injury can occur at any time during harvesting, drying and storage conditioning of seeds. The seed coat color and leachate conductivity of soybean has been correlated with seed longevity and black seed coat color has been reported to be positively correlated with better seed longevity. In order to understand the physico-chemical attributes related to soybean seed longevity, biochemical and molecular analysis of the parents exhibiting black (Birsasoya-1) and yellow seed coat colour (EC 241780) and the eleven F3 progenies of the cross exhibiting brown, yellow and black seed coat colour was carried out. The results revealed that vita-E, lignin, calcium content and activity of antioxidative enzymes appeared to be positively correlated with soybean seed longevity and levels were higher in black and brown seed coat color progenies. The lipid peroxidation rate was inversely related to membrane injury caused by ROS and comparatively much less lipid peroxidation rate was recorded in black and brown seed coat colour parents and progenies having better seed longevity. The SSR primers Satt162, Satt523 and Satt453 which are either linked with seed coat colour and seed permeability exhibited a specific size allelic fragments in soybean genotypes and crosses with better seed longevity.
