“…For example, House (1985) and Bantilan et al (2004) showed that low temperatures reduce the growth rate in sorghum, increasing the crop growth cycle duration and, consequently, decreasing biomass yield. Moreover, Reddy and Patil (2015) reported an increase in tillering when sorghum genotypes are exposed to low temperatures, which is valued by breeders since these are directly linked to the increased biomass production (Murray et al, 2008). On the other hand, the maximum temperature presented low correlations with all factors, showing less influence on the genotypes performance across environments.…”

The present field experiment was conducted at Agricultural College Farm, Bapatla during kharif (June-November), 2019 to know the impact of botanicals against fall armyworm, S. frugiperda and their natural enemies (coccinellids, spiders and predatory bugs) in the sorghum ecosystem. Among the botanicals, the highest population reduction of FAW egg masses and larval population was recorded in NSKE @ 5% (71.43 and 60.87%, respectively), green chilli pod extract @ 5% (61.90 and 54.35%, respectively), neem leaf extract @ 5% (69.05 and 45.65%, respectively) and garlic bulb extract @ 5% (52.38 and 54.35%, respectively) treated plots. The botanicals that are used in the experiment were found safe from natural enemies. The maximum population of natural enemies i.e., coccinellids, spiders and predatory bugs was recorded in pongamia leaf extract @ 5% (0.16, 0.22 and 0.10 plant-1, respectively) whereas, the least was observed in emamectin benzoate 5 SG @ 11 g a.i. ha-1 (0.02, 0.02 and 0.01 plant-1 respectively) treated plots. The emamectin benzoate 5 SG @ 11 g a.i. ha-1 presented an adverse effect on natural enemies whereas no or few natural enemies were observed compared to botanical extracts. Therefore, it is recommended that spraying of botanicals has to be done four times at weekly intervals to keep FAW populations below economic injury level until crop maturity and these treatments were also found safe to natural enemies of FAW.

To improve the genetic-breeding characteristics of maternal forms, to increase their adaptive potential in breeding hybrids of agricultural crops (sorghum, African millet, corn, rice, sunflower, winter rye, etc.), various types of CMS are used. The article presents the results of studying the collection of CMS sorghum lines obtained on the basis of new sources of sterility (A1, A2, A3, A4, A5, A6, 9E and M-35-1A) by agronomic characteristics. On the experimental field of the Institute in 2014-2018. 21 lines were sown in a wide-row way with row spacing of 70 cm and a density of standing of 100 thousand plants per 1 ha. The allocation of plots of 7.7 m2 is randomized, in triplicate. The use of cluster analysis for the minimum of Euclidean distances allowed us to group CMS lines according to similar studied features: the 1st group includes 9; 2nd - 4; 3rd and 4th - 3 each; 5th and 6th - 1 line each. One-way analysis of variance confirms the validity of differences between groups by 18 selection criteria, with the exception of the extension of the panicle leg. A significant variation in vegetative (V = 11.0-21.6%) and generative traits (V = 13.2-28.4%) was found. The smallest coefficient of variation was revealed by the duration of the seedling-flowering interphase period — 4.8%, which indicates the maturity of most lines (in A2 KVV 181, A2 Suzern light, A2 AGS - 46.6 days). A five-year test of the source material made it possible to identify productive lines of the 5th and 6th groups (grain productivity 5.07-5.36, biomass - 18.30-20.70 t / ha); weakly growing lines of the 3rd group (total and productive bushiness 1.12-1.14), low-growing lines of the 1st group (plant height 81.0 cm). A1 Efremovskoye 2 is distinguished by tallness (143.3 cm), large sizes of flag and largest leaves (areas of 150.0 and 254.2 cm2, respectively). The selection of sterile lines with predetermined traits helps to optimize the selection process and their targeted use in crossbreeding programs.
