Brassica napus was synthesized by hybridization between its diploid progenitor species B. rapa and B. oleracea followed by chromosome doubling. Cross with B. rapa as a female parent was only successful. Among three colchicine treatments (0.10, 0.15, and 0.20%), 0.15% gave the highest success (86%) of chromosome doubling in the hybrids (AC; 2n = 19). Synthetic B. napus (AACC, 2n = 38) was identi...

A study was conducted to estimate genetic variability, correlation and direct indirect effects of yield attributes on seed fourteen Bangladeshi varieties Brassica rapa. High heritability coupled with high advance recorded in a number secondary branches plant-1, siliqua plant-1 seeds siliqua-1 indicating the additive genes controlling traits. Significant positive association were observed primar...

Fruit production and arrangement within the raceme were studied in two dioecious populations of Ceratonia siliqua (Leguminosae: Caesalpinioideae), an arboreal species that produces caulogenous racemes (emerging only from the old branches) with numerous flowers. Fruit production per raceme was low and similar between years and populations and even between individuals. During flowering, there wer...

A field experiment was conducted during Rabi of 2022-23 at the Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study Response potassium and spacing on growth yield Mustard. The treatments consist 30,40,50 kg/ha 25 x 10 cm, 35 45 cm. There were 9 each replicated thrice. soil experi...

to determine the association between genetic parameters and traits in chickpea (cicer arietinum l.) genotypes, a field experiment was conducted with 17 chickpea genotypes using a randomized complete block design with four replications at the ilam agricultural and natural resources research center in the 2004 growing season. genetic parameters including genetic, environmental and phenotypic vari...

drought stress is one of the important problems in arid and semi_arid regions. drought stress take place in plants when available water is lesser than evapotranspiration. in order to evaluate the effect of drought stress on morphological traits and yield of three medicinal plants an experiment was carried out during the 2010 year in research greenhouse of faculity of agriculture, ferdowsi unive...

A field experiment was conducted during Rabi season of 2022-23 at the Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj (U.P.) India. To study Response bio-fertilizers phosphorus on growth yield Toria. The treatments consist Bio-fertilizers like Azotobacter – (20g/kg seeds), PSB (10g/kg seeds) + Pho...
