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.

Abstract


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.
