No. Poster–73 IMPACT OF COTTON LEAF CURL DISEASE (CLCuD) ON YIELD AND QUALITY OF FIBRE IN Bt COTTON IN PUNJAB Daljeet Singh, J.S. Gill, R.K. Gumber and Ramandeep Singh Punjab Agricultural University, Regional Station, India Cotton is one of the most important cash crops in India. Cotton leaf curl disease (CLCuD) , caused by a single stranded circular Gemini virus consisting of DNA A and two sat...

Historically, the primary objective of cotton (Gossypium hirsutum L.) breeding programs was to improve the quantity and quality of cotton fiber. Because of the added value of cottonseed and its many uses, including a feed and human food source, there is interest in developing cotton breeding programs that focus improvement efforts simultaneously on cotton fiber and seed. Genetic analysis of cot...

to determine the effect of sowing dates (22 oct., 5 nov., 21 nov. and 5 dec.) on the green pod and dry seed yield of faba bean (vicia faba), field experiments were conducted using rcb design with four replications for three cropping seasons (1995-1998) at hashem abad research station in golestan province. result, of combined analysis of variance showed that 22 oct. and 21 nov. produced higher g...

The plant growth regulator BM was formulated to stimulate seed production and fruit growth. In this study, it was hypothesized that the addition of BM would increase levels of polyamines for seed induction and have a direct benefit of improving fertilization and seed set in cotton. This benefit may enhance yield under extreme environmental conditions when endogenous polyamines content is reduced.

Impact of hybridization and irradiation in isolation of superior segregants in four crosses of desi cotton were studied and compared between F2 and F2M2 progenies. The F2M2 progenies of four crosses recorded higher per cent of superior segregants compared to F2 progenies for boll number, boll weight and halo length excepting in KS-16 x MB-3200 cross. Out of four F2M2 progenies, RDC-53 x 9747 cr...

The research work comprising genetic studies for oil, fatty acid profile, seed cotton yield and lint percentage in eight parental lines (SLH-284, CIM-446, CIM-473, CIM-496, CIM-499, CIM-506, CIM-554, CIM-707) and their F3 populations was carried out during 2011 and 2012 at The University of Agriculture, Peshawar and Nuclear Institute for Food and Agriculture, Peshawar Pakistan. The genetic pote...

This study was carried out to determine the effects of putrescine(Put) and humic acid (HA) foliar applications on growth, yield and chemical composition of Egyptian cotton (Gossypium barbadense L. cv. Giza 90)plants grown under saline soil condition. A soil mixture of, clay: sand (1:1), was used as a plant growing media. Three different doses of putrescine (0, 1 and 2 ppm) and humic acid (0, 1 ...

AIMS To investigate the aetiology of seed and boll rot of cotton grown in South Carolina (SC). METHODS AND RESULTS Bacteria were isolated from diseased locules of cotton bolls collected in a field in SC, USA and tested for the ability to cause comparable disease symptoms in greenhouse grown cotton fruit. Spontaneously generated rifampicin-resistant (Rif(r)) mutants of the isolates were used i...
