An analysis of the persistence and potency of film-coated seed protectant as influenced by various
storage parameters
Provedor de dados: 28
Autores: Jacob, Sherry Rachel; Arunkumar, M B; Gopal, Madhuban; Srivastava, Chitra; Sinha, S N.
An efficient delivery system for seed-protectant chemicals is needed in light of several disadvantages of conventional seed
treatment methods. This study evaluates the efficacy of film-coat application in maintaining the persistence and potency of
imidacloprid on Lycopersicon esculentum (L.) Mill. seeds after simultaneous storage under ambient and regulated environment in
paper and aluminium packages. High-performance liquid chromatography (HPLC) revealed 0.135 mg kg−1 of herbage material to
be the threshold value beyond which absolute control was obtained, and with film coating the latter was achieved even with
half-dosage seed treatment, irrespective of the storage condition. The technique provided early protection to the crop and also
nullified the...

Provedor de dados: 28
Autores: BHARADWAJ , C; Mishra, R; Rao, SK; TARA SATYAVATHI, C.
Genetic segregation patterns were observed for awning in 4 generations of the crosses of Jawahar New plant Type (JNPT): 'JNPT
63-01 ' x 'Pusa Basrnati 1' and 'JNPT 89' x 'Pusa Basrnati 1' in parental, F,, F, and F, generations. The observations clearly indicate
that awn character in 'Pusa Basrnati 1' is governed by a dominant gene and presence of awn to be dominant over its absence.

uptake by pearl millet (Pennisetum glaucum)
Provedor de dados: 28
Autores: Singh, R K; Chakraborty, Debashis; Garg, R N; Sharma, P K; Sharma, U C.
A study was conducted during rainy (kharif) season of 2004 and 2005 in a sandy loam soil of the semi-arid region of Delhi to
study the effect of different doses of nitrogen (30, 60 and 120 kg/ha) under rainfed and irrigated condition on ‘HHB 67’ pearl
millet [Pennisetum glaucum (L.) R.Br. emend. stuntz.]. Growth rate varied between different seasonal weather condition, but the
relative growth rate and the partitioning of dry matter was similar. Yields were more influenced by water application than the
nitrogen doses. Maximum yield (3.19 and 3.10 tonnes/ha in 2004 and 2005, respectively) was recorded with 120 kg N/ha
application under irrigated condition, while optimum yield (2.30 and 2.40 tonnes/ha in 2004 and 2005, respectively) and water-use
efficiency...

Estimation of Parameters Responsible for the Generation of Off-Flavor in Some Indian Varieties of
Soybeans
Provedor de dados: 28
Autores: Dahuja, Anil; Madaan, T R.
Production of hydroperoxides and volatile aldehydes, having low olfactory thresholds by lipoxygenase (LOX) action, is an
important problem in the effective use of soybeans as food ingredients. In this study, researchers examined sixteen soybean
varieties forLOXactivity, thiobarbituric acid (TBA) number, a measure of lipid peroxides, and carbonyl value, an index of ketone
compounds, responsible for off-flavor. Among the soybeans tested, PK416 and JS7015 had the lowest levels of LOX activity,
TBA number as well as carbonyl value. The highest value for these parameters were observed in Pb-1 and Bragg. These results
suggest that PK416 and JS7015 could be excellent soybean sources for making good quality soy products.

Genetic architecture in some new plant-type-based crosses of rice (Oryza sativa L.) for yield
components and yield contributing traits
Provedor de dados: 28
Autores: Bharadwaj , C; Rajesh , Mishra; Rao , S K; Tara Satyavathi , C; Mishra, D.K.
The inherent complexity of yield and its environmental effects are the main constraints to yield improvement. An easier approach
would be to improve the component traits that finally manifest into higher yield gains. Though a lot of literature has been
generated in rice (Oryza sativa L.) on the type of gene actions, the success of breeding programmes in new plant types (NPTs) for
yield has been hampered by lack of meaningful knowledge on the inheritance of yield components and yield contributing traits.
Genes governing the character expressions in such altered genotypes were described. The F2 frequency distribution showed
continuous variation indicating the polygenic nature of inheritance of these traits. In general, it was observed that dominant gene...

Mango explant browning: Effect of ontogenic age, mycorrhization and pre-treatments
Provedor de dados: 28
Autores: Krishna, Hare; Sairam, R K; Singh, S K; Patel, V B; Sharma, R R; Nain, Lata; Sachdev, A.
The in vitro performance of mango shoot culture is delimited by several factors, of which explant necrosis and media browning
are considered as major constraints for successful exploitation of such an important commercial crop. Our results showed that
source of explants had a significant effect on the performance of in vitro cultures of mango. The variations in survival of explants
collected from glasshouse grown seedlings and field-grown stock plants indicated towards differences between their
physiological/ ontogenic age. Though, chronologically, both are young, the glasshouse grown shoots are ontogenetically younger
and; therefore, responded better over field-grown shoots. Improved performance of explants harvested from mycorrhizal plants
suggests...

“Molecular Marker-Assisted Crop Breeding: Principles, Methods and Applications”
Provedor de dados: 28
The science of genetics that surfaced in the 19th century is the core of all biological researches now. It is still growing and the new
developments are accumulating at an unprecedented rate. Its core principles have been effectively utilized for genetic
improvement of the crop species resulting in increased harvest with good quality. However, to meet the increasing demand for
food crops, it becomes imperative for interdisciplinary approaches where genetics and plant breeding shall play the key role. With
the recent advances in biotechnology, information technology, software-assisted quantitative genetics, crop modeling, etc. have
opened new vistas for genetic dissection of complex traits of economic importance in crop plants. Similarly, the information...

Prediction of miRNAs in Bombyx mori through Computational Approaches
Provedor de dados: 28
Autores: Mishra, A K; Lobiyal, D K.
In this paper, we have used rule-based approach to predict mature miRNA from pre-miRNAs of Bombyx moori (Silk worm). For
rule based approach, it is important to have a set of rules. Unfortunately, to the best of our knowledge, miRNA related literature
does not provide well-defined set of rules for miRNA prediction. Therefore, the challenge in this research was to derive a set of
rules from known data set of related species. We have made an attempt to derive a set of rules from the known miRNA and
pre-miRNA data sets of Drosophila melanogaster and Apis mellifera. The derivation of rules is based on the dominating features
identified using PCA and infogain method applied by authors in their previous work. Based on these rule set a PERL script is
written to...

Autores: Gupta, H S; Agrawal, P K; Mahajan, V; Bisht, G S; Kumar, A; Verma, P; Srivastava, A; Saha, Supradip; Babu, R; Pant,
M C; Mani, V P.
Quality protein maize (QPM) originally developed in the late 1990s at CIMMYT, Mexico possesses roughly twice as much
usable protein as normal maize grown in the tropics. The improved quality of the protein in QPM is due to enhancement in
lysine and tryptophan – the two limiting amino acids that are known to be regulated by opaque2 gene and associated modifiers.
QPM has widely been adopted for cultivation in the developing world to fight protein malnutrition. India, QPM was released for
commercial cultivation almost a decade ago by introducing QPM lines from CIMMYT. However, all these inbred lines are of
longer duration and thus, give rise to QPM hybrids of full season maturity. Utilizing marker assisted selection we transferred
opaque2, a...
