A range wide sample of Dalbergia sissoo Roxb. provenances scattered over almost the entire natural range in India was studied for pod seed and germination characteristics.

Significant genetic variation has been observed among the seed sources for germination characteristics such as germination value germination percent germination energy and germination rate. The variation observed for morphological characters of pod and seed is geographical. Seed width showed a significant positive trend with altitude and seed weight. The strong correlation between germination capacity germination value germination energy and germination rate indicated that the improvement in one character would improve the other and this kind of relationship is important for early selection of provenances. Six provenances i.e. Kanpur (U.P) Muzaffarnagar (U.P) Allahabad (U.P) Jabalpur (M.P) Lalitpur (U.P) and Khilalabad (U.P) were found to be most vigorous based upon germination parameters and can be initially used for large scale afforestation programmes.

Abstract

A range wide sample of Dalbergia sissoo Roxb. provenances scattered over almost the entire natural range in India was studied for pod seed and germination characteristics. For all the studied characters provenances were found to be a significant source of variation. Significant genetic variation has been observed among the seed sources for germination characteristics such as germination value germination percent germination energy and germination rate. The variation observed for morphological characters of pod and seed is geographical. Seed width showed a significant positive trend with altitude and seed weight. The strong correlation between germination capacity germination value germination energy and germination rate indicated that the improvement in one character would improve the other and this kind of relationship is important for early selection of provenances. Six provenances i.e. Kanpur (U.P) Muzaffarnagar (U.P) Allahabad (U.P) Jabalpur (M.P) Lalitpur (U.P) and Khilalabad (U.P) were found to be most vigorous based upon germination parameters and can be initially used for large scale afforestation programmes. Seed source variation appeared to be gregarious in the studied seed and pod characteristics and sporadic/discontinuous in the case of germination parameters. None of the germination traits was correlated with any of the geographical cordinates of the sources. Provenance of Jabalpur (M.P) was comparatively heterogenous. Results emphasize the importance of selecting suitable provenances before large scale tree planting commences.
