Polymorphic Identification of Simple Sequence Repeat (SSR) Marker for Developing Aluminum-Tolerance Upland Rice

Abstract

SSR marker is one of the genetic markers widely applied in plant breeding programs. The application of molecular markers in plant breeding is meant to accelerate the selection of cross-progeny. The research aimed to identify the SSR primers polymorphism between the parent and control that linked to Al tolerance and verify the cross-progeny of five crosses. The result gained from 37 SSR primers used in this study showed that only nine primers are polymorphic. These nine polymorphic primers are RM257, RM214, RM247, RM205, RM490, RM262, RM569, RM271, and RM19. The application of polymorphic markers on five cross-progeny which have shown the same band pattern as the parents and tolerant control on the use of 9 SSR primers recorded as follows: RM257 2 lines, RM214 5 lines, RM247 5 lines, RM205 lines, RM490 13 lines, RM262 5 lines, RM569 7 lines, RM271 4 lines, and RM19 6 lines. The selected SSR primers linked to Al tolerance in this research can be used as a reference for molecular breeding strategies to develop new Al tolerance rice varieties in dryland conditions.

Effects of different tea manure on growth and yield of selected chilli pepper (Capsicum annum) varieties under DEBESMSCAT Masbate Condition, Philippines

“…Utilizing an organic fertilizer like compost has an impact on the height, flowering, and harvesting ages of chilli plants. Additionally, organic fertilizer can restore a damaged field by enhancing the physical and chemical properties of the soil, enhancing soil biological activity, and expanding the soil's capacity to hold water [8].…”

Physicochemical Properties and Eating Quality of Promising Crossbred Upland Rice Lines Developed From Superior Parental Genotypes

“…The pertinent study aimed to determine the quality of 12 crossbred upland rice lines based on the milled rice's physicochemical properties and eating quality. The observed rice lines were derivatives of crossbreeding parental genotypes with either aluminum tolerance or high yield, with their genetic markers identified (Mulyaningsih et al, 2016;Anggraheni et al, 2020). The output expectation will be complementary data for future superior upland rice varieties that meet national standards and consumer preference.…”
