Study on wheat quality of stored wheat (Triticum aestivum L.) in laboratory

Abstract

The study was conducted during 2018-19 at Seed Technology Research Unit, M. P. K. V. Rahuri for testing the effect of storage period on seed quality of wheat (Triticum spp. L.) for laboratory observations which were evaluated in Factorial Completely Randomized Design (FCRD) with three replications. The experiment consist of four varieties viz., Godavari (V1), Panchavati (V2), Tapovan (V3) and Trimbak (V4), and three seed ages viz., fresh seed (A0), Rvd Ist seed (A1) and Rvd IInd seed (A2). The observations on seed quality character such as germination percentage, moisture content, root shoot length, seedling dry weight, vigour index (I), vigour index (II), mycoflora percentage was recorded monthly interval up to seven months at laboratory condition. The study revealed that, among the varieties significant differences were observed. The seed quality parameters viz., germination percentage (90.00%), root shoot length (32.23 cm), seedling dry weight (0.285 g) vigour index (I) (2905.06), vigour index (II) (25.66) were better in variety Godavari followed by Panchavati, Tapovan and Trimbak. Among the seed ages, fresh seed produced higher seed yield than others, Rvd IInd seed recorded less but stable performance. Seed quality parameters viz., germination percentage (94.64%), root-shoot length (32.61 cm), seedling dry weight (0.290 gm), vigour index (I) (3080.47) and vigour index (II) (27.43) were better in the fresh seed. However, mycoflora percentage was higher in Rvd IInd and lower in fresh seed. The wheat seeds can maintain the 85.75% germination percentage at the age of 31st months which is above IMSCS (85%).
