Total seed protein variability in a sample of 163 entries of year-bean (Phaseolus polyanthus), including wild, feral and cultivated forms of the whole range of distribution in Latin America was studied using 1-dimensional SDS/PAGE and 2-dimensional IEF-SDS/PAGE. Ten different patterns were observ...

The effect of microwaves on the eradication of fungal and bacterial pathogens in cassava sexual seed was investigated. Healthy mature fruits were collected and dried under ambient conditions. Seeds were selected according to specific wt. by placing them in a glass of water and discarding those th...

Seed accounts for a significant proportion of potato production cost and its quality cannot be compromised for profitable potato production. Potato is conventionally vegetatively propagated, has a low multiplication rate and requires many generations to bulk the requisite seed quantity often in o...

A tomato variety known as ‘Srijana’ developed by Nepal Agricultural Research Council (NARC) has been substantially popular among Nepalese farmers and entrepreneurs. To understand the seed value chain of the Srijana hybrid tomato, a survey was conducted in 2014/15 with public research and extensio...

Segregating progenies from 19 crosses of potato (Solanum tuberosum L.) developed at the International Potato Center (CIP), Peru were tested during 2008-2013 for adaptation and yield attributes in the sub-tropical plains of India i.e. Modipuram, Uttar Pradesh. The progenitors of the crosses showed...

A morphobiometric analysis of seeds of Phaseolus L. from 50 populations belonging to 31 wild and cultivated taxa was carried out. Based on the outcome of the study an identifi cation key was developed comprising 25 morphotypes of which 23 related to individual taxa The different patterns of semi...
