Citrus sinensis (L.) Osbeck (sweet orange) is one of the most important commercially cultivated fruit crops of Citrus and occupies the second position after mandarins in India. Genetic diversity and inter-relationship among 22 cultivars of C. sinensis were analyzed based on morphological and RAPD markers. A total of 99 bands were generated with 20 RAPD(More)
Mandarin (Citrus reticulata Blanco) is the second most important citrus crop worldwide. A total of 25 mandarin accessions collected from North, Central and North-Eastern regions of India, were evaluated for phenotypic and genotypic variations using morphological and random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR) markers.(More)
Genetic stability of Morus alba, Morus indica, Morus laevigata (indigenous collection) and Morus species (exotic collection) have been studied in in vitro regenerated plants of mulberry (fresh, before and after cryopreservation) using random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) markers. This study examined the genetic(More)
Buchanania lanzan Spreng. (Chironji) is a socio-economically important underutilized fruit and life support species of tribal populations of north, west and central India. A survey and germplasm collection programme undertaken in the Indian states of Rajasthan, Gujarat and Madhya Pradesh observed that B. lanzan is found as natural wild in the forest,(More)
Manilkara hexandra (Roxb.) Dubard (Khirni) is a socio-economically important fruit and nut species of tribal population of tropical deciduous forests of western and central India. Survey and collection missions were undertaken to study the extent of variability and socio-economic importance of Khirni germplasm in diversity rich areas of Rajasthan, Gujarat,(More)
The effect of temperature on germination and days taken for germination was evaluated in Carica papaya cvs., ‘Pune selection-3’ and ‘Pusa Dwarf’. The highest average seed germination per cent was observed in the month of July (96.8 and 93.0 %), followed by August (94 and 88.5 %), whereas the lowest average seed germination was observed in the month of(More)
Phylogenetic relationships of Indian Citron (Citrus medica L.) with other important Citrus species have been inferred through sequence analyses of rbcL and matK gene region of chloroplast DNA. The study was based on 23 accessions of Citrus genotypes representing 15 taxa of Indian Citrus, collected from wild, semi-wild, and domesticated stocks. The phylogeny(More)
Indian mustard, Brassica juncea (Linn.) Czernj and Cosson is ravaged by several diseases viz., Alternaria blight, Sclerotinia stem rot, white rust and nutrient deficiency causing substantial yield loss. A field experiment was conducted on the integrated management of major diseases in Indian mustard through different combinations of balanced fertilization,(More)
The mango (Mangifera indica L.) is native to South and Southeast Asia, from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics. It is the national fruit of India. In India, harvest and sale of mangoes take place during March-May and the fruits have high economic value in India. Studies were first time(More)
In vitro storage conditions of Citrus limon (L.) Burm. cv. Novoafonsky were developed in this study. Three explants were used: nodal regenerants, seedlings, and micrografted plants. The results obtained in present investigation confirmed that slow growth maintenance of lemon microplants on ½ MS medium allows to store micro-grafted plants and seedlings for 8(More)
