The effect of different seed coating treatments, comprising polymer, fungicide, insecticide, polymer-fungicide and polymer-insecticide combinations was studied on the longevity and seed quality parameters of okra during a twelve month storage period (January 2018 to December 2018). The experimental material consisted of carry over okra seeds (variety P-8) from the Kharif season 2015. The seeds were coated during December 2016 and stored for 24 months, however, here only the findings from 13th to 24th month are presented. At the end of storage period (24 months), recorded data revealed that irrespective of seed coating, seed deteriorated due to decline in vigour probably because increased fungal infection and aging of seed. However, two treatments viz., T6 -polymer + vitavax 200 @ 2 g/kg of seed and T - polymer + flowable thiram @ 2.4 ml/kg of seed were found 4 significantly superior for all seed quality parameters viz., germination (%) - first count (%), final count (%), speed of germination, seedling length (cm), seedling dry weight (g), seedling vigour index-I, seedling vigour index -II, electrical conductivity (m mho/cm/g) and field emergence (%) over T1 - untreated control at the end of storage period. Hence, these treatments offer an effective alternative means to secure safe seed storage.Keywords

Characterization plays a significant role in plant science. It enables easy discrimination between varieties and helps in defining a variety. In this study, seven released and/in release pipeline soybean varieties of Himachal Pradesh were morphologically characterised using DUS descriptors. Each variety was tagged to the set of morphological characteristics. Further, the characterization revealed that 11 characters out of 21 namely seed shape, seed colour, seed cotyledon colour, seed hilum colour, seed size, plant growth habit, leaf shape, leaf colour, flower colour, pod pubescence colour and pod colour were very informative in providing a sound identification of seven soybean varieties of Himachal Pradesh. The information generated could be a ready reckoner for all the actors involved in undertaking activities related to maintenance breeding during seed multiplication and for genetic purity assessment using the Grow Out Test.Keywords
