Abstract:
The present investigation entitled “Studies on genotypes of shoot growth characters of Ber (
Zizyphus mauritiana Lamk.)” was conducted at H.R.C., Patharchatta, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand in the year 2010-11. The experiment was comprised of twenty four treatments of ber genotypes i.e., Banarasi Pewandi, Chhuhara, Chinese, Dandan, Illaichi, Kaithli, Kala Gola, Narikeli, Nazuk, Noki, Rohtaki Gola, Sanaur 1, Sanaur 2, Sanaur 3, Sanaur 4, Sanaur 5, Sanaur 6, Selected Safeda, Seo, Thornless, Umran, Wallaiti, ZG2 and ZG3. The investigation were carried out with the objective of evaluating shoot growth at fortnightly interval. The experiment was laid out in randomized block design. The results showed that maximum shoot length was observed with Noki which was at par with Kaithali, Kala Gola,Banarasi Pewandi and Nazuk. The maximum number of leaves per shoot was recorded with Sanaur 6 while minimum was observed with Umran. The maximum number of lateral branches per shoot recorded was observed with Sanaur 2 cultivar while minimum was observed with Sanaur 5. The mean data of the fortnightly interval showed that shoot length, number of leaves per shoot and number of lateral branches per shoot were followed the single sigmoid growth curve in all the genotypes.
