“…Hence, such daily stress factors as fluctuations in light intensity and temperature during growth conditions can be easily overcome in order to achieve better growth [11]. In addition, the radiation of the seed results in stem thickening and strengthening [12].…”

“…Number of mutants of different crop plants have been developed and released in different countries of the world with improvement in some characters (Ahloowalia et al, 2004). Such mutants are reported in cotton Muthusamy and Jayabalan, 2011), soybean (Hofmann et al, 2004), potato (Li et al, 2005), cassava (Joseph et al, 2004, Buttibwa et al, 2015, Chrysanthemum (Datta et al, 2005) and groundnut .…”

To cite this paper: Haidar, S. and M. AbstractThis paper describes about development of cotton mutant NIAB-2008, developed through pollen irradiation technique with improved yield and fibre quality. A local variety NIAB-78 was crossed with exotic line REBA-288 using irradiated pollen @10 Gray (Gy) of gamma rays before cross pollination. The purpose of the study was to create new genetic variability and select the desirable new cotton mutants. After irradiation and hybridization different generations were raised to evaluate the effect of irradiation treatment and induction of mutations. Significant variations from control/parents were observed in evaluated generations. From M1 seed, the M2 population was raised and different desirable mutants were selected. The selected mutants were evaluated in mutated generations (M3-M6) for different yield contributing traits and yield potential along with fibre quality and variations from parents were observed. From selected mutants, an elite mutant i.e., M-7/09, later named as NIAB-2008 was finally selected. It was evaluated for seed cotton yield, adaptability, resistance/tolerance to diseases, and fibre quality in different trials. It produced 32.9% higher seed cotton yield compared to standard CIM-496 at local NIAB trials. It produced 32.7% and 32.2% higher seed cotton yield compared to standard in provincial coordinated cotton trials (PCCT) and in national coordinated varietal trials (NCVT) respectively. The mutant NIAB-2008 has desirable fibre quality traits i.e., ginning out turn (GOT) 37.99%, fibre length 31.16 mm (long staple category), fibre fineness 4.74 µg/inch, uniformity index 83.5%, fibre maturity 80.5% and fibre strength 92.2 thousand pounds per square inch (TPPSI). Its distinguish characteristics are early maturity, high yielding, short stature, good boll bearing and better tolerance to cotton leaf curl virus-Burewala strain (CLCuV-B) disease. From these results it is concluded that low dose pollen irradiation technique has effectively stimulate/increase the different yield and yield contributing traits, fibre quality and tolerance to diseases in cotton and this technique is proved economical.

Ab stractIn vi tro microtuberization pro vides an ad e quate ex per i men tal model for the phys i o log i cal and met a bolic stud ies of tuberization and the pre lim i nary screen ings of po ten tial po tato geno types. The ef fects of sa line stress at 0-80 mmol con cen tration on in vi tro tuberization of two po tato cultivars were in vesti gated in this study. With an in crease in the salt con cen tra tion, the microtuberization of po tato was ei ther de layed by 5-10 days (20 and 40 mmol NaCl) or in hib ited com pletely (80 mmol NaCl) in ad di tion to the re duc tion in microtuber yields. The two po tato ge no types stud ied showed dif fer ent trends in to tal sol u ble sug ars, su crose and starch con tents of microtubers under NaCl stress, while glu cose and fruc tose lev els re mained un changed. The vi ta min C con tent in microtubers of two potato ge no types was re duced by salt stress. Sa lin ity ap plied from 20 to 60 mmol pro gres sively in creased proline and malondi aldehyde (MDA) lev els in microtubers of both the potato cultivars. In ge no type Zihuabai, NaCl at a low con cen tration (20 mmol) led to a sig nif i cant in crease in peroxidase (POD) and polyphenoloxiadase (PPO) ac tiv i ties, while in Jingshi-2, the PPO ac tiv ity de creased pro gres sively with an increase in NaCl con cen tra tions. Ge no type Zihuabai ex hib ited higher tol er ance to salt stress than Jingshi-2 un der in vi tro condi tions. These re sults could be used for pre lim i nary se lec tions of salt tol er ance in po tato breed ing programmes. In tro duc tionStud ies on soil sa lin ity or sa line wa ter are gain ing im por tance in ag ri cul ture be cause it af fects the growth and de vel op ment of crops by creating a stress and thereby re sults in yield loss. Salt stress in duced var i ous bio chem i cal and phys i o log i cal responses in plants and af fected al most all plant processes in clud ing pho to syn the sis, growth and de vel op ment (Nemoto and Sasakuma 2002). Sa linity tol er ance by plants de pends pri mar ily on the geno type that de ter mined al ter ations on pro cesses such as up take and trans port of salt by roots, together with met a bolic and phys i o log i cal events (Winicov 1993). Screen ing of dif fer ent cultivars for abiotic stress tol er ance was nec es sary not only for breed ing of po tato to abiotic stress, but also for pro vid ing better ma te rial for study ing the abiotic stress tol er ance mech a nism (Sergeeva et al. 2000).Po tato is clas si fied as one of mod er ately sen si tive crops of sa lin ity tol er ant group (Katerji et al. 2003).
