“…Many studies on rice heterosis breeding for superior combinations have been done for better selection in the breeding program [7][8][9][10][11]. Molecular markers application is widely used in breeding programs to confirm the hybridity of putative F1 progenies due to being highly polymorphic, not manipulated by the environmental factors, and representing the genetic constitution of the species [12]. The microsatellite (SSR) marker is the most popular molecular marker to confirm the F1 hybrid because it is highly polymorphic and informative [13].…”

A new high-yielding mutant rice cultivar, IS21, has been released by the Malaysian Nuclear Agency (MNA) in 2021. This cultivar matures in 105-108 days after transplanting. Since there is a need to reduce days to maturity (DTM) in most Malaysian rice mega-varieties to minimise the impacts of abiotic and biotic stresses, crossing IS21 with early maturing rice genotypes could be an efficient strategy to address these issues. Preliminary screening has successfully identified two early maturing and shorter plant statue rice genotypes, MR220CL2 and UKMRC16. Therefore, these rice genotypes were crossed to IS21 to generate two F1 populations. These F1 populations (IS21 × MR220CL2 and IS21 × UKMRC16) were planted in the MNA glasshouse with parental lines from December 2021 to March 2022. The agro-morphological data for F1 populations and parental lines were recorded and analysed using the RStudio software package. The putative F1 progenies were confirmed using two polymorphic simple sequence repeat (SSR) SSR markers, RM628 and RM140. About 75% of the putative F1 are F1 hybrids. IS21 × MR220CL2 F1 progenies showed better morpho-agronomical performances compared to IS21 × UKMRC16 F1 progenies. This crossing combination also had positive mid-parents and better parent heterosis values of all evaluated traits except for thousand-grain weight, days to flowering and DTM. This study suggested the potential use of IS21 x MR220CL2 F1 progenies for rice breeding programmes with high-yielding and early maturity traits.

“…We chose common bean (also known as dry bean or French bean) as a highly important staple crop and primary source of protein for humans in many developing countries [ 43 , 44 , 45 , 46 ] for which relatively few studies explored Trichoderma spp. as means of biological control [ 47 ], perhaps because a study that screened 101 strains of Trichoderma identified only seven strains with a growth promoting effect [ 48 ], or simply because bean generates limited economic gains. Besides the beforementioned screening, dosage-dependent effects of a T. harzianum inoculum on the nutrient uptake and seed yield of bean plants were reported from two studies under pathogen-free conditions [ 40 , 49 ].…”

Root colonizing Trichoderma fungi can stimulate plant immunity, but net effects are strain × cultivar-specific and changing ambient conditions further contribute to variable outcomes. Here, we used four Trichoderma spp. to inoculate seeds of four common bean (Phaseolus vulgaris) cultivars and explored in three different experimental setups the effects on fungal anthracnose after leaf inoculation with Colletotrichum lindemuthianum. Plants growing in pots with field soil under greenhouse conditions exhibited the highest and those in the open field the lowest overall levels of disease. Among 48 Trichoderma strain × bean cultivar × setup combinations, Trichoderma-inoculation enhanced disease in six and decreased disease in ten cases, but with the exception of T. asperellum B6-inoculated Negro San Luis beans, the strain × cultivar-specific effects on anthracnose severity differed among the setups, and anthracnose severity did not predict seed yield in the open field. In the case of Flor de Mayo beans, Trichoderma even reduced yield in anthracnose-free field plots, although this effect was counterbalanced in anthracnose-infected plots. We consider our work as a case study that calls for stronger emphasis on field experiments in the early phases of screenings of Trichoderma inoculants as plant biostimulants.
