Abstract

Mutagenic effectiveness and efficiency of gamma rays were studied in the four inbreds of sunflower. Gamma rays produced high frequency as well as a wide spectrum in mutation. The frequency of mutation was high at higher dose of mutagen. The mutagenic effectiveness and efficiency was calculated based on biological damage. In M1 generation based on seed lethality and pollen sterility and M2 generation was carefully screened for various chlorophyll and viable mutation. Mutagenic effectiveness and efficiency reduced with the increase in dose or concentration. In present investigation higher dose of 20kR was very effective and efficient in induction of mutation in all the genotypes studied except CMS- 104B where 15 kR dose was effective and efficient.

Abstract

One hundred and twenty four F₄ families of sesame derived from straight and reciprocal crosses made between E-8 (commercial cultivar) and Tamil Nadu Local (land race) were evaluated during Kharif, 2010 to assess genetic variability, heritability (broad sense) and genetic advance for ten quantitative characters. Analysis of variance revealed highly significant difference among the F₄ families for days to 50 per cent flowering, days to maturity, plant height, number of branches per plant, number of capsules per plant, distance from ground to first capsule and number of seeds per capsule. High GCV and PCV were observed for branches per plant, capsules per plant and seed yield per plant. High heritability coupled with high genetic advance as per cent mean was observed for plant height, branches per plant, capsules per plant, capsule length, distance from ground to first capsule, seeds per capsule, 1000 seed weight and seed yield per plant.

Abstract

In order to study inheritance of alternaria blight resistance in sesame, straight and reciprocal crosses were made between RT-273 (resistant) and Gulbarga local black (susceptible) during Kharif-2007. Screening of F₂ and F₃ progenies against Alternaria blight, and segregation analysis showed that resistance is governed by single dominant gene. Further screening of F₄ families under field condition during Kharif-2010 confirmed the single dominant gene governing the Alternaria blight resistance in cultivated sesame.

Abstract

Methotrexate (MTX) is used as an anticancer drug in many types of cancer associated with organ toxicities. It generates free radicals responsible for tissue damage in organs like testis. Coconut water, a natural drink known for its nutritive values also possess components, which are rich in antioxidants. The present study was a novel study to evaluate the benefits of yellow and green varieties of coconut water in testicular damage caused by methotrexate in experimental animals. The study proved that, both the varieties of coconut water restored testicular structure and functions by recovering sperm function, testicular enzymes, antioxidant enzymes and improvement in tissue microscopy. We conclude that both green and yellow coconut water are beneficial and can be used as a natural remedy for methotrexate induced testicular toxicity.
