“…Till to date only HYVs have been used for generating potato plantlets in vitro. These HYVs have, however, shown to be salinity susceptible (Rahman et al 2013). But under present scenario of climate change, it is important to develop regeneration protocol for salt tolerant potato varieties.…”

In vitro response of four explants namely, leaf, shoot apex, nodal and internodal, in three stress tolerant Bangladeshi potato varieties, viz. Zaubilati, Shadaguti and Challisha were tested. Of all the varieties, Shadaguti responded best for all the explants. Among the explants nodal segment responded best, followed by shoot apex. For all these explants and varieties, shoot regeneration response was tested in response to two cytokines, BAP and Kn. When compared between BAP and Kn supplementation, Kn treatment performed better than that of BAP for nodal and shoot apex, while opposite was observed for remaining explants. Interestingly, hormone free basal PROP medium was found to be best for nodal explants of both Zaubilati and Challisha varieties. While nodal explants of Shadaguti showed the best result in 0.5 mg/l Kn. Shoot apex performed best in 0.5 mg/l Kn for all the varieties. As an explant both internode and leaf did not perform well. Direct regeneration from these explants was found best in PROP + 0.2 mg/l GA3 + 0.5 mg/l IAA; 1.0 mg/l BAP, 1.5 mg/l BAP and 2.0 mg/l BAP for Zaubilai, Challisha and Shadaguti, respectively. For rooting, of the in vitro grown shoots half strength of PROP medium supplemented with 0.5 mg/l IBA was found to be best. Cent percent survival of transplanted plantlets was recorded. The successful protocol for in vitro regeneration was developed which can be used for large scale production of these abiotic stress tolerant potato varieties.

“…The HYVs are under cultivation to meet the food demand. But recently, susceptibility of these HYVs toward salinity stress has resulted in tuber yield loss, thus, making them unsuitable for cultivation (Rahman et al 2013, Uddin et al 2010. To overcome these problems we need to cultivate stress tolerant varieties to ensure higher production.…”

“…Furthermore, the potato has a high export potential. However, due to low yield of local cultivars and saline susceptibility of available high yielding varieties (HYVs) are not economically suitable for their cultivation in saline soil (Rahman et al, 2013;Uddin et al, 2010). Therefore, high yielding salt tolerant exotic potato cultivars such as CIP 102, CIP 106, CIP 111, CIP 117, CIP 120, BARI Alu 72 (CIP 139), BARI Alu 73 (CIP 127) and CIP 136 can be cultivated in saline belt areas.…”

The aim of the experiment is to study in vitro regeneration efficiency of international potato center (CIP)-bred salt tolerant potato genotypes under salt stress condition and to identify effective potato genotype(s) for saline belt areas of Bangladesh. An in vitro shoot bioassay of eight CIP-bred potato genotypes viz. CIP 102, CIP 106, CIP 111, CIP 117, CIP 124, BARI Alu 72 (CIP 139), and BARI Alu 73 (CIP 127) and CIP 136 were used. In this study, single node of these genotypes was cultured in MS media supplemented with 0, 80, 100, 120, 140 and 160 mM NaCl. Among the eight genotypes, BARI Alu 72 (CIP 139) showed the highest tolerance against salinity up to 160 mM NaCl (14.61 dS/m) for all studied parameters (except shoot and root initiation) with the highest plant height (9.67 cm), leaves number (13.60), nodes number (9.50), root length (6.50 cm), roots number (7.80), fresh weight of shoot (536.1 mg) and root (205.60 mg). On the other hand, CIP 106 was found the most susceptible genotype against salinity showing its highest salinity tolerance up to 120 mM NaCl (10.96 dS/m) with maximum plant height (7.17 cm), leaves number (12.50), nodes number (6.50), root length (7.50 cm), roots number (9.7), fresh weight of shoot (572.3 mg) and root (250 mg). The experiment's findings corroborated CIP's findings that they were salt tolerant, as well as recommended for their cultivation suitability in saline-affected area in Bangladesh.
