Abstract
Vigour is one of the important characteristic of seed quality. No vigour test is likely to perform best to all crops. The vigour test should be crop specific and very little information is available about the vigour test for finger millet and barnyard millet.
The experiments on vigour tests viz., physical, physiological and biochemical tests were conducted in CRD (Complete Randomized Design) with four replication. There was six treatments consist of six varieties, three each of finger millet (PRM-1, PRM-2 and VL-352) and barnyard millet (PRB-903, VL-207 and PRJ-1). All vigour test experiments procedure was followed as per standard guidelines. The field experiment consist of six treatment (T1 PRM-1, T2 PRM-2, T3 VL-352, T4 PRB-903, T5 VL-207 and T6 PRJ-1) was laid out in the RBD (Randomized Block Design) with four replication. The field emergence, seedling establishment and field emergence index was recorded during the field experiment. The data were analyzed statistically to find out the result of the study in laboratory and field conditions.
Finger millet variety PRM-2 and PRB-903 of barnyard millet were recorded significantly higher test weight, seed density, first count, final count, standard germination, seedling shoot length, seedling root length, total seedling length, seedling fresh weight, seedling dry weight, seedling vigour index I, seedling vigour index II, speed of germination, relative growth index, paper piercing test, cool germination test, mean daily germination, radical emergence, accelerated ageing test and electrical conductivity than VL-352 of finger millet and VL-207 of barnyard millet. Similarly, in field study PRM-2 and PRB-903 were recorded significantly higher field emergence, seedling establishment and field emergence index.
The field emergence was correlated with different vigour test viz. test weight, final count, standard germination, seedling vigour index I and relative growth index in both finger millet and barnyard millet. The highly positive and significant correlation was found in test weight(r= 0.859** in finger millet and r= 0.807** in barnyard millet) and seedling vigour index I (r= 0.990** in finger millet and r= 0.999** in barnyard millet) with field emergence.
On the basis of the study it could be concluded that PRM-2 of finger millet and PRB-903 of barnyard millet were more vigorous. The seedling vigour index I and test weight could be considered to predicting the field emergence of finger millet and barnyard millet.
