High efficiency macropropagation of potato (Solanum tuberosum L.) cv. Kufri Jyoti in Kumaun Hills
The present study demonstrated the use of various PGR combinations for efficient in vitro regeneration of cv. kufri jyoti in kumaun hills. Best callus induction and proliferation was observed in MS medium supplemented with 13.59 µM 2,4-D alone and 2,4-D + kinetin (9.06 + 1.16 µM) out of different concentrations of 2,4-D (4.53 to 18.12 µM) alone and 2,4-D (0 to 18.12 µM) with kinetin (1.16...

Identification of sorghum (Sorghum bicolor L. Moench) landraces tolerant to post flowering drought stress using drought tolerance indices
Drought stress occurring during the post-flowering growth stage of sorghum can cause considerable reduction in yield. In order to identify drought tolerant Eritrean sorghum landraces and assess efficiency of drought tolerance indices, twenty five sorghum (Sorghum bicolor L. Moench) accessions were evaluated in split plot design with three replications. Fully irrigated and drought stress treatments were assigned in main...

Assessment of genetic variability and yield stability in chickpea (Cicer arietinum L.) cultivars in River Nile State, Sudan
Eight chickpea cultivars (Shendi, Jabel Marra, Wad Hamid, Atmor, Hwata, Burgeig, Salwa and Matama) were evaluated for genetic variability, yield stability and contribution of yield attributes to seed yield. Field experiments were carried out for four seasons (2007/2008, 2009/2010, 2010/2011 and 2011/2012) at Hudeiba Research Farm in River Nile State, Sudan. Randomized complete block design with six replications was...

Differential morphological, physiological, and molecular responses to water deficit stress in sugarcane
This study was designed to characterize morphological, physiological and molecular responses of sugarcane genotypes to a simulated water deficit stress. Two genotypes (TSP05-4: Drought-tolerant; TCP02-4589: Drought-sensitive) were subjected to a 20-day water deficit treatment and an 8-day recovery period. Leaf photosynthesis (Pn), transpiration rate (E), stomatal conductance (Gs), leaf greenness index (SPAD) and...

Variability of root and physiological traits of different maturity groups of maize (Zea mays L.)
Maize (Zea mays L.) is a major commercial crop, with high potential for production due to high solar radiation and low night temperature in sub-Saharan Africa. It is also the second most susceptible to drought among cereals, although phenotypic traits can be altered to improve drought resistance. Pot and field experiments were conducted to study the variability in root and physiological traits in different maturity...
